Shenzhen 20 million square meters "industrial upstairs" workshop space project started to attract investment.

  Cctv news On January 10th, Shenzhen held the investment invitation meeting for the "20+8" 20 million square meters "Industrial Upstairs" workshop space project, which pushed a large number of high-quality "Industrial Upstairs" projects to the stage. Huang Min, member of the Standing Committee of Shenzhen Municipal Committee and executive deputy mayor, Zheng Hongbo, member of the Standing Committee of Shenzhen Municipal Committee and Party Group of the Municipal Government, and Wang Youpeng, vice chairman of the CPPCC, attended the event.

  The so-called "industrial upstairs" refers to the new industrial space mode of industrial production in high-rise buildings, which can promote the transformation and upgrading of manufacturing industry and alleviate the shortage of land resources. It is reported that Shenzhen plans to build 20 million square meters of high-quality, economical and customized factory space every year for five consecutive years, which is about equal to building two "industrial upstairs" factories with the size of Shekou Industrial Zone in Shenzhen every year.

  Zheng Hongbo said in his speech that the Shenzhen Municipal Party Committee and the Municipal Government have always adhered to the foundation of the manufacturing industry, focused on the development of advanced manufacturing industry as the key task of building a modern industrial system, and guaranteed industrial space as urban infrastructure. In June 2022, Shenzhen issued the "Spatial Layout Planning of 20 Advanced Manufacturing Parks", with a total planned land area of about 300 square kilometers. In November 2022, Shenzhen launched the "Industrial Upstairs" plan, and built 20 million square meters of high-quality, economical and customized factory space every year for five consecutive years.

  The reason why "high quality" is emphasized is that the "Industrial Upstairs" project in Shenzhen has high quality and high quality guarantee, which can meet the demand of manufacturing enterprises for high-load and large-area production space. "Economy" means that "industry goes upstairs" is leased and sold to enterprises at a more affordable price, which is more cost-effective. It is reported that the current "industrial upstairs" high-quality factory rents average 35 yuan per square meter per month. "Customization" is because the project builder of "Industrial Upstairs" can tailor the production space according to the needs of enterprises.

  Shi Jisheng, chairman of Shenzhen Aikerui Electric Co., Ltd. said at the scene that the relocation of enterprises in the medical device industry will consume a lot of financial and material resources. Last year, Aikerui Electric chose "industry upstairs" and moved to Shenzhen Baolong Specialized Special New Industrial Park. It not only solves the problem of production space of large medical instruments with sufficient height and load-bearing. At the same time, the project also provides supporting resources such as canteens and hotels to help enterprises retain talents.

  It is reported that there are currently 72 "industrial upstairs" projects in Shenzhen, with a land area of 854.8 square meters and a factory area of 23.065 million square meters. More than a month after the launch of the plan, more than 300 enterprises put forward the demand for more than 5 million square meters of factories, which fully demonstrated the stamina of Shenzhen’s industrial development.

  At present, driven by the extraordinary strength and speed of the Shenzhen Municipal Party Committee and Municipal Government, a large number of high-quality "industrial upstairs" projects have been planned and built in all districts of the city.

  At the meeting, the relevant leaders of Longgang District introduced the basic situation of the "Industry Upstairs" project in detail, representatives of Xinqiao East and Honghualing Park introduced the relevant situation of the project, representatives of construction workers in the special zone introduced the relevant situation of high-quality industrial space, representatives of CDB introduced the financial products, representatives of demanding enterprises made speeches, and the project unit signed a lease intention agreement with representatives of demanding enterprises.

Depth Holography: The Encounter of Holography and Depth Neural Network

Written by | Zheng Shanshan and Zhang Xiangyu

Description | This article is submitted by the author (research group).

With the rapid development of mathematical optimization and computing hardware, deep neural network(Deep Neural Networks, DNN)(noun explanation >) has become a powerful tool to solve many challenging problems in various fields, including decision-making, computational imaging, holographic technology and so on.

Since its development in 1947, holography(holography)(noun explanation >) has become an important and extensive technology, and has applications in various fields of optical engineering, including optical imaging, microscopy, metrology, three-dimensional (3D) display and so on. Holography means containing all information of light waves, which is physically divided into two processes: recording and reconstruction of wavefront, both of which can be realized by optical or digital methods.

At present, the two different fields of holography and deep learning have merged with each other, forming a new interdisciplinary field-depth holography.

Recently, from Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of SciencesSitu guohaiResearcher with Deep holography For the topic of Light: Advanced Manufacturing In this paper, a review article was published, and the progress of depth holography was comprehensively reviewed.holographic(holography)andDeep neural network(DNN)The mutual promotion relationship between them.

Dnn has been proved in holographic reconstruction and computer generated holography.(computer-generated Holography, CGH)Almost all aspects of the application;

● Holography has the ability of interconnection and parallel processing of light speed, which is an optical realization of DNN, that is, optical neural network.(optical neural networks, ONN)(noun explanation >).

In this paper, the basic theory and architecture of DNN are briefly introduced, then some important progress and research trends of depth holography are discussed, and finally its future prospect is prospected. I hope this review can promote the further development of this field.

Deep Neural Networks: A Concise Introduction

The conceptual framework of DNN is shown in Figure 1. Feedforward neural network, or multilayer perceptron.(MLP)There is an input layer, an output layer, and one or more hidden layers. Each layer can have a different number of neurons, called perceptron; And each unit receives the weighted sum of its inputs from the upper layer.(Except for the first layer, its input is the original image to be processed by NN). The goal of feedforward neural network is to optimize an NN model to approximate a continuous function.trainAft learning that network parameter,The mapping from the input space x to the output space y can be realized.

Figure 1. Conceptual architecture of DNN (Source: Light: Advanced Manufacturing)

Compared with the traditional holographic technology based on physics, DNN method has been proved to have unique advantages. As long as there is enough data, DNN can learn features from the higher-level structure composed of lower-level features, but it can’t clearly express the exact physics of the system, which leads to great challenges to the generalization and interpretability of the method.

Therefore, we very much hope that we canGive full play to the advantages of DNN and physical model at the same time, develop DNN based on physical information.(Physics-informed DNN).

● Physical integration(physical fusion), or a single physical DNN.

It directly inputs the solution of physical model as DNN model.(part).

● Residual physics(residual  physics), or recursive physical information DNN

Add physical solutions to the output of DNN, so that DNN model only needs to learn the mismatch between model-based solutions and the real situation.

● Regularized physics(physical  regularization), or concatenated physical information DNN.

The regularization term in a set of physical constraints is used to punish the network solution. The regularization term can be used as part of the loss function or through the physical reconstruction process.  

● Embedded physics(embedded physics)DNN

As shown in Figure 2, the central idea is to bring the physical model into the network optimization cycle.

Figure 2. Typical architecture of DNN embedded in physics (Source: Light: Advanced Manufacturing)

● Network approximate physics

As the name implies, the physical model is approximated by using DNN.

Holographic reconstruction

Hologram can be regarded as the superposition of object light and reference beam. The intuitive method of holographic reconstruction is based on the physical model of diffraction, that is, the numerical calculation of wave diffraction process. Off-axis holography can be solved by spatial filtering, but spatial filtering will bring the loss of high-frequency components, which greatly hinders the quality of reconstructed images. For coaxial holography, the removal of zero order is relatively simple, so most of the research on coaxial holography reconstruction is to deal with twins.

Physically, twin images are actually out-of-focus copies of reconstructed object images, which can be eliminated by subtracting out-of-focus images. At present, the most widely used strategy is to adjust some physical parameters of the optical system and obtain the corresponding holograms, so as to establish a small linear equation set, and to link the recorded holograms with the tuning parameters, and then solve the object wavefront.

Mathematically, the twin image artifact is caused by the lack of phase when the hologram is recorded. This shows that if the missing phase of the hologram can be solved, the twin image artifacts can be solved.

Holography inspired by DNN

1) The most direct method: "end to end" DNN

EHoloNet developed by ResNet and U-Net: receiving the original digital hologram as input, and generating the phase object wavefront without artifacts;

Y-network architecture: simultaneously reconstruct intensity and phase from a single digital hologram;

It is also possible to generate a countermeasure network(GAN)Implementation, training data does not need to be paired.

2) Physical fusion, or DNN of single physics.

The traditional numerical free space is used to propagate back to the target plane, and then the amplitude and phase of the reconstructed wavefront are sent to DNN respectively, and all these artifacts are removed by training.

3) physically embedded DNN

As shown in Figure 3, this strategy has two obvious advantages by incorporating the physical imaging model into the traditional DNN:First of all, it does not need any data for pre-training; Secondly, the reconstructed image satisfies the constraints imposed by the physical model, which is interpretable.

DNN model in PhysenNet can be replaced by other neural networks, depending on the task at hand. For example, researchers have successfully incorporated the phase imaging model into the GAN network.

Figure 3. Schematic diagram of DNN incorporating physical model: phase imaging (Source: Light: Science & Applications, 9: 77 (2020).)

In addition, DNN method can also be used to solve various problems related to holography.Such as phase unwrapping, autofocus, phase distortion compensation, speckle suppression, computer generated holography (CGH).

DNN inspired by holographic technology

Holographic technology is to realize optical neural network.(ONN)One of the important ways.

The early research includes the optical realization of fully connected neural network and Hopfield model, which is a cyclic neural network.(RNN)The foundation of. Holographic neural network does not use logical neurons like digital neural network, but relies on the interconnection of hologram itself. In a fully connected holographic neural network, the weights are stored in the pixels of the hologram.(neuron)Medium. a layer or deck(hologram)Each neuron simply modulates the light shining on it from the upstream layer and then illuminates the downstream layer. Holographic neural network can be realized by photorefractive crystal, which is a three-dimensional device in itself and may store billions of weight data. Therefore, it is hopeful to solve large-scale reverse problems in principle.

Figure 4. Schematic diagram of diffraction depth neural network

(a) DNN contains a plurality of transmission (or reflection) layers, in which each point on the layers acts as a neuron with a complex transmission (or reflection) coefficient, and the transmission or reflection coefficient of each layer can be trained using deep learning, thereby performing a function between the input and output planes of the network. After the learning stage, the design of D2NN is fixed; Once it is manufactured or printed in 3D, it can perform the learned functions at the speed of light. Different types of diffraction depth neural networks: (b) classification and (c) imaging. (Source: Science,361(2018))

The modern realization of holographic neural network takes advantage of diffraction, so it is named diffraction depth neural network.(D2NN), as shown in Figure 4. In hardware implementation, the hologram in D2NN is actually a diffractive optical element.(DOE)It can be realized by 3D printing, nanotechnology, or electrically addressable digital micromirror devices.(DMD)Get. Like many other optical neural networks, the original D2NN was trained offline. In order to implement better training strategies, researchers have made a lot of efforts, such as back propagation technology to update unit weights through gradient transformation from Euclidean space to Riemannian space, and methods to realize optical grouping. People have also studied the applications of D2NN in logic operation, optical information processing, holographic reconstruction, pulse shaping, single pixel machine vision of spectral coding and so on.

Summary and prospect

The integration of holography and neurocomputing has greatly promoted each other’s development, and also provided us with a wonderful field to explore.

For holography inspired by DNN, this paper discusses five different ways to incorporate physical information, and shows their applications in solving various problems related to holography.

● In addition to trying different DNN architectures,An important trend is to incorporate physical models into DNN models.. This idea has been paid close attention by researchers in different fields.

● PhysenNet embedded in physical model has obvious advantages, but its optimization speed is slow.For lightweight network structure and more effective training algorithmMade a request.

● Comprehensive utilization of the advantages of physical prior and traditional data-driven methodsIt can make the training more effective, improve generalization and increase interpretability.

For DNN inspired by holographic technology, most of the research published so far focuses on optical reasoning. The parallel processing ability of the holographic neural network at the speed of light does guarantee powerful reasoning ability, even surpassing the performance of Tesla V100 tensor core GPU, the top product of Nvidia, in some tasks.

In order to give full play to the advantages of optics, it is necessary toOn-line training of network by optical means.There are many possibilities to effectively implement most basic functions in DNN. 

● Relying on the development of new optical materials and equipmentThe wave can be modulated at high speed at sub-wavelength scale to improve the performance of D2NN.

● The rapid development of neural computing provides us with more powerful algorithms., such as spike neural synaptic network (SNN), can simulate the behavior and learning potential of the brain. The applicability and potential of these new algorithms in holographic technology need to be tapped.

China’s Internet Literature: From "Cool Literature" to "One of the Four Cultural Wonders in the World"

Text/Yangcheng Evening News reporter Sun Lei

site of activity

"I eat tomatoes"

"Squid who loves diving"

On October 12th, China Online Literature Influence List (2022) was released and Guangdong-Hong Kong-Macao Greater Bay Area Online Literature High-quality Development Seminar was held in Guangzhou. Online literature writers, critics, platform leaders and industry representatives from all over the country gathered together to discuss the present situation and future of online literature.

The event was hosted by the Chinese Writers Association, the Propaganda Department of the Guangdong Provincial Committee of the Communist Party of China, and co-organized by the Network Literature Center of the Chinese Writers Association, the Guangdong Writers Association and Huacheng College of Literature.

I eat tomatoes, love diving squid, drinkers, bandits, I think about saving and other well-known online writers appeared at the venue, as well as online literary critics, platform leaders, cultural industry representatives from all over the country to participate in the activities.

After 20 or 30 years’ development, the online literature born on the Internet platform has gradually bid farewell to the early state of "barbaric growth and mud and sand", constantly breaking through the typed writing of cool articles and gradually moving towards the mainstream, high-quality and even classic development path. The content ecology of online literature has been further optimized, the trend of high-quality products has become stronger, and the trend of "going out to sea" of online literature has gradually become a scale.

The Realistic Trend of Web Theme: Hi? Worry?

On the evening of October 12th, the China Online Literature Influence List (2022) was officially released. After strict initial evaluation, re-evaluation, final evaluation and online voting by readers, the Network Literature Center of China Writers Association launched four lists: online novel list, IP influence list, overseas communication list and newcomer list, with 29 online literary works and 8 newcomer writers on the list.

The reporter found that in this list of works, the theme structure of online literature is more optimized, and the realistic theme has become the "new favorite" of online texts, and excellent works are frequent. Among the works on the list of online novels, works such as Critical Path and Biography of Shanghai Mortal closely follow the pulse of the times and write about real life.

On April 10th this year, the "Research Report on the Development of Network Literature in China in 2022" issued by the Institute of Literature of China Academy of Social Sciences also pointed out this trend: realistic works entered the "golden age" with a high compound growth rate of 37.2%.

According to Huang Fayou, chairman of Shandong Writers Association and professor of Shandong University College of Literature, the prosperity of online literature’s realistic theme creation is, in a sense, an important manifestation of online literature’s mainstream and high-quality practice. "In recent years, the creation of realistic themes of online literature has made remarkable progress and development, which has injected new vitality into online literature and pushed online literature to break through the bottleneck of development, with a broader vision and a more diverse pattern."

The same theme of reform and opening up, online literature works are not only more vivid, but also more interesting, and there is no lack of depth and temperature. The application of network literature techniques and visual narrative means also brings new aesthetics to the creation of realistic themes. Huang Fayou said that, like "Daguo Heavy Industry", it has a deep understanding of the machinery industry, and is full of respect for the exploration spirit of technicians and the fighting spirit of workers who are not afraid of difficulties. The works have a kind of affectionate power.

Wu Lanqi Muge, an associate professor at the School of Humanities, Wenzhou University, emphasized that the greatest feature of online literature is its freedom, popularity and tradition of telling stories, which allows us to have leisure, entertainment and games, which is a very important reason for its existence. "If all online literature develops to realistic literature or high-quality literature, it will certainly fail to learn from the strengths of traditional literature. Network literature has some reasons for its existence. Among some fantasy, fantasy and story-telling theme types, we can see some innovations in ideological artistry and literature and art that are no less than traditional literature and fine literature. In fact, it already has the advantages and disadvantages of traditional literature. "

In addition to realistic themes, sci-fi works, as one of the most important online categories, are still growing at a high speed. In 2022, "science" appeared nearly 250,000 times in the book review area. In this list of works, "We Live in Nanjing" and "Nomenclature of the Night" have developed gorgeous imagination, written fantastic fables in the vast universe, and explored the boundaries of sci-fi theme creation.

With the development of science and technology and the popularity of sci-fi film and television dramas, the post-90s and post-00s are rapidly pouring into the production and dissemination of sci-fi online literature in the activity field of the Internet, which is naturally labeled as "younger". The "Z generation" writers have gradually become the main creative force, and the newcomers of online writers combine the latest cutting-edge technology to create, bringing a new look and atmosphere to the development of the industry.

"Going out", China traditional culture is sought after.

According to the data released by the Network Literature Center of the Chinese Writers Association, by the end of 2022, the overseas market scale of China’s online literature exceeded 3 billion yuan, with more than 16,000 online works exported overseas, and overseas users exceeded 150 million, covering more than 200 countries and regions in the world.

From 2004, qidian began to sell the copyright of online novels to the whole world, to 2006, the translated works of Ghost Blowing Lights and Zhu Xian opened the Southeast Asian market, and then overseas originality and AI translation were launched, and IP adaptation was popular overseas. China’s online literature has spread all over the world, and some people even listed China’s online literature as "the four cultural wonders of the world" along with Hollywood blockbusters, Japanese anime and Korean TV dramas.

On the overseas communication list published this time, "The Return of the Warrior" triggered readers in more than 170 countries and regions around the world to "catch up" with a compact plot and suspense story lines, with more than 500 million hits; Cosmic Pro combines various elements such as reiki revival, live martial arts broadcast and life evolution, and shows the powerful imagination and narrative power of China’s online literature overseas …

It is worth mentioning that, in the tide of "net writing goes to sea", the works that inherit Chinese excellent traditional culture have made outstanding achievements, attracting many overseas readers, and the international communication effect is outstanding.

According to Tian Zhiguo, deputy editor-in-chief of Reading Group, through investigation, they found that overseas readers like China traditional culture and modern China style. In 2022, China-related words appeared 150,000 times in readers’ comments. In readers’ related discussions, the most mentioned China elements include food, martial arts, tea art and panda.

Tian Zhiguo said that with the continuous going out to sea of online articles, the literary style relying on the Internet has become an important entertainment content in Southeast Asia and North America, which is loved by local young people. "We have opened up localized originality in the local area. The main types of works are 15 categories and more than 100 subcategories, mainly focusing on five major themes: city, game competition, science fiction, oriental fantasy and western fantasy. Many of the oriental fantasy themes are influenced by China’s traditional culture and have a strong Chinese style in theme setting and character setting. "

In recent years, many platforms have made efforts in the direction of audio and short video to promote the spread of China’s online literature overseas. According to Xie Guangcai, director and executive vice president of Chinese Online Group, as far as overseas communication is concerned, the current "ReelShort" short play can be described as a shining star in the European and American markets, and its user scale has developed very rapidly, making it a sample for short plays to go to sea. "The short drama of network development is a good outlet in the current two or three years, but its quality is the top priority of commercial operation."

Tong Ye, CEO of Twitter Technology, said that going out to sea is not just a text going out, but more importantly, letting Chinese culture go out. Xie Sipeng, editor-in-chief of tomato novels, also stressed that both the content and the mode of going out to sea are all China’s online articles going out to sea, and they all bear the mission and heavy responsibility of spreading China culture.

The degree of mainstreaming has increased, and excellent originality is still less.

While the iron is hot, you need to be hard. Whether the theme turns or the online text goes out to sea, high-quality online literature works are needed. This is also the core value of this list release and seminar: focusing on the mainstream and quality creation of online literature.

China’s online literature has been in a state of natural growth for quite a long time since it came into being spontaneously. Internet literature, which was born on the Internet platform, pays too much attention to market efficiency and pursues "fast", "long" and "cool" blindly, resulting in the problems of rough quality, vulgar content and deviation from mainstream values, which can be described as "barbaric growth and mud and sand".

In recent years, with the continuous promotion of the trend of quality content, the mainstream degree of online literature at home and abroad has been significantly improved in 2022: in China, 144 online works have been permanently collected by the National Library, and 10 digital versions of online works have been collected in the China National Edition Museum; Overseas, 16 China websites have been collected by the British Library, and they have spread to more than 200 countries and regions around the world, with 901 million users visiting overseas websites.

"It is necessary to promote the mainstream and quality of online literature innovation." Hu Bangsheng, member of the party group and secretary of the Secretariat of the Chinese Writers Association, observed that there are a large number of online literary works and rich types, but there are still few excellent original contents. He believes that holding an online literary and cultural heritage forum and publishing a list of online novels is to inherit the Chinese context, explore the development path, guide online writers to adhere to the correct creative orientation, and launch more online literary masterpieces.

"Mainstreaming, quality and classicalization are a plan for the whole online literature industry, which requires that online literature must serve this era. This requirement also invisibly constrains the creation of each of our online writers, regardless of personal will." According to Ouyang Youquan, a professor at Central South University, the current development of online literature is facing many changes. With the rise of audio and video industrialization, as the source of content, online literature must produce high-quality texts so that our creation can stand, spread and stay.

Guangdong is one of the cradles of online literature in China, and it is also the province with the largest number of online writers, and many "great god" writers who are famous all over the network have been born. According to Zhang Peizhong, Party Secretary and Full-time Vice Chairman of Guangdong Writers Association, by the end of 2022, there were more than 200,000 online literature writers in Guangdong, including nearly 40,000 people who signed contracts with websites and wrote, and 150 head writers. The number of authors, works and readers ranked among the top in China, with strong development momentum and broad prospects. "We should further strengthen the creation of high-quality products, speed up the IP transformation, increase the online literature’s going to sea, and truly realize the two-way development and two-way empowerment of Guangdong-Hong Kong-Macao Greater Bay Area’s online literature and cultural industries", and make Guangdong-Hong Kong-Macao Greater Bay Area an important pole in the development of China’s online literature.

"I eat tomatoes":

Focus on creation, not following the market trend.

Network writer "I eat tomatoes", whose real name is Zhu Hongzhi, is called "tomato". In 2005, he began to serialize The Legend of the Star Peak in qidian, and since then, he has started the journey of online literature creation, and has successively published works such as The Star Change, Panlong, Swallowing the Starry Sky, The Age of the Wild, and The Professional Player of the Universe, breaking many online records.

Among them, Panlong, Swallowing the Starry Sky, Cosmic Professional Player and many other works are also representative works of online writing, which have been translated into English, Korean, Thai, Indonesian and other languages.

Yangcheng Evening News: For you personally, what is the biggest change in online literature over the years?

I eat tomatoes: the external environment has been changing, and we need to adhere to the initial intention of creation while adapting to the environment. Online novels developed vigorously in 2002, and it has been about 20 years now. Its future still has great potential and possibility. All we have to do is write a good story, and your story may spread explosively at the right time. You can’t follow the trend just because of what the market is, like the short video of the fire now, not that you have to do it. Writers still have to concentrate on creation, write a good work, and then wait for the opportunity.

Yangcheng Evening News: Now discussing online literature, many critics have put forward the expectation of "mainstreaming" and "quality". As an online writer, do you want your works to enter the mainstream vision?

I eat tomatoes: the ancients said, "If you take it, you will get it." You can set a high goal and then work hard in this direction. As for the result, I think it will be left to future generations to evaluate.

Yangcheng Evening News: Apart from online literature, have you tried to create more profound and serious literature?

I eat tomatoes: the boundaries of serious literature are actually rather vague. The essence of literature is to convey ideas. If the ideas you convey can still have a good influence on people after a hundred years, then I think your works are excellent literary works, and you are creating with a very serious attitude, which is exactly what I have been pursuing.

Yangcheng Evening News: Where does your creative source come from? What is the creative motivation?

I eat tomatoes: the source of my creation is the bits and pieces in my life, like sometimes looking at the blue sky and white clouds outside, I will conceive a very illusory world in my mind, or watching a news, which will also trigger some associations. These are the sources of creative materials.

If you are motivated to create, I feel that people still have to pursue something, and they can’t live in a daze all the time. I started writing in 2005, and it’s been 18 years now, which is equivalent to doing it all the time during the most creative period. Since this is the most important career in your life, I still hope to create some excellent works. If there are still works that are widely welcomed by readers many years later, it is still a very fulfilling thing for me.

Yangcheng Evening News: In your opinion, how does online literature creation relate to the times?

I eat tomatoes: as a member of society, the author will of course be influenced by various social news when he creates. However, for me personally, there is a certain time difference. Because when I write a novel, it is often long, up to several million words, so before I start writing, I will first determine the outline of the novel, and once it is decided, it will not be easily changed. Just like Jin Yong’s novels, there are many foreshadowing in the early stage, and these foreshadowing have already decided the direction of the later article. So the touch of news events may generally be integrated into the creation of my next work.

Yangcheng Evening News: Do you analyze readers’ preferences when creating?

I eat tomatoes: I may listen to readers’ opinions in the process of preparation, but once I start writing, I will stick to telling the story in my heart. I have written many creative themes, such as Xian Xia, science fiction, magic, city and so on. I like to challenge some unwritten themes, and different attempts are more fresh.

Yangcheng Evening News: What do you think or suggest about China’s online literature going out to sea?

I eat tomatoes: the first step of online literature is translation, so the translator is very important. A good translator should first like the work itself, and then be able to translate it into other languages smoothly. Besides the translator, the original work itself is fundamental. Another is the platform, which needs a suitable platform to spread excellent online literary works and reach overseas readers.

"Squid who loves diving":

Net articles with deep expression will have more audiences.

The online writer "Squid Who Loves Diving", whose real name is vilen, is a signing writer at the starting point and a platinum writer of Reading Group. He has written many online novels, such as "The Record of Death" (formerly known as "The Way to Immortality"), "The Divine Immortal", "The Master of Mysticity" and so on. Among them, the number of hits on the Internet of "The Divine Works of Olympiad Mathematics" exceeded 12 million, ranking first in the list of online novels in China in 2015 by Chinese Writers Association, and winning the first Biennial Award for Excellence in Chinese Online Literature.

He has also won the second "Mao Dun Literature Newcomer Award of Chinese Literature Foundation" and the third "Orange Melon Network Literature Award" and other honors. In 2016, he was elected as the vice chairman of the 8th Sichuan Writers Association. In 2019, he was elected as the chairman of Sichuan Network Writers Association.

Yangcheng Evening News: What do you think of the proposition of "classicalization" of online literature?

Squid who loves diving: I think there may be a long way to go to talk about the "classicalization" of online literature. What we should do first is to make it fine. As a creator, classicalization is definitely an unavoidable desire. But at this stage, as far as I am concerned, I can only say that I am constantly exploring in my own creative field and writing more timeless works, which can be passed down as much as possible.

Yangcheng Evening News: Will deep thoughts conflict with the pursuit of story in online literature?

Squid who loves diving: Not really, because online literature is aimed at hundreds of millions of readers. Some readers prefer relaxed and cool articles, while others want to see some works that can touch people’s hearts and arouse resonance. Network literature can’t please everyone, and it can only attract favorite readers as much as possible in its own field. On this basis, online literature with deep expression will have more audiences in the future.

Yangcheng Evening News: In your opinion, how has online literature changed in the past 20 or 20 years?

Squid who loves diving: the progress of technology has brought many changes to online literature. The earliest online literature was only serialized on the internet, and it was still a literary expression in essence. Later, with the development of technology, the era of mobile internet was ushered in, and many readers used their mobile phones to read books. At this time, as the author of online literature, in order to optimize the mobile phone reading experience, he will try to split long sentences into short sentences and remove large inner monologues. Now, with the assistance of AI, it can help to name the supporting role of the work, and even provide some story outlines, giving some ideas and inspiration. Of course, technology is always only an aid, which cannot replace the uniqueness of human creation, nor can it simulate the inner mental journey of each individual.

Yangcheng Evening News: What changes have you brought by engaging in online literature creation?

Squid who loves diving: I am very grateful to the industry of online literature, which makes me jump out of the established box.

China’s first near-space solar unmanned aerial vehicle was successfully tested.

  Xinhua News Agency, Beijing, June 13th Title: "Climb" the China "Rainbow" in the 20,000-meter sky — — China’s first near-space solar unmanned aerial vehicle was successfully tested.

  Xinhua News Agency reporters Li Song and Bai Guolong

  The wingspan is 45 meters, the surface is covered with solar panels, and the shape is "science fiction"; The next flight can last for months or even years, and it has the characteristics of "quasi-satellite"; It can be used as an "air mobile WIFI" base station, real-time monitoring and positioning at high altitude, and has a broad application prospect … … Recently, China’s Rainbow Solar UAV successfully completed the high-altitude flight test of more than 20,000 meters, which made China the third country to master the technology of solar UAV in near space after the United States and Britain.

  Solar unmanned aerial vehicle (UAV) with completely independent intellectual property rights is expected to become another classic of China’s "intellectual creation".

  Ultra-high altitude, long endurance and easy support — — China "Rainbow" climbed high into the sky.

  Recently, in an airport in northwest China, the weather was fine, and the rainbow solar drone with a wingspan of 45 meters slowly slipped out along the runway and flew off the runway smoothly, gradually climbing to the adjacent space of 20,000 meters. During the flight of more than 15 hours, the UAV’s flight state was stable and its attitude was controllable, and it flew in an orderly manner according to the designed track, and finally achieved a smooth landing, and the test flight was a complete success.

  The load capacity exceeds that of foreign UAVs of the same type, the key technologies are localized, and it has a wide application prospect in the military and civilian fields … … As the latest achievement of China’s "intelligent creation", Rainbow Solar UAV has reached the advanced level in the world with its three magic weapons of super high altitude, long endurance and easy support.

  20— from the ground; The airspace of 100 kilometers is called the adjacent space. For the traditional fuel-consuming aircraft, too thin air makes the engine power drop significantly and loses its "place of use". However, this is a space where drones covered with solar panels show their advantages. "Relying on sunlight to provide the whole machine with energy and electric propeller propulsion, it is expected to fly for several months or even longer in the future, so that solar drones can show their talents at high altitude and long voyage." Li Guangjia, head of the Rainbow Solar UAV Project, introduced.

  Talking about the technical characteristics of the Rainbow Solar UAV, Shi Wen, the chief engineer of the Rainbow Series UAV, is also gushing, like a few treasures. "Another technical advantage of the Rainbow Solar UAV lies in its high operating cost-effectiveness ratio. Its airborne system is simple, and there is no need for refueling and other support equipment. Due to the long flight time, there is no need to frequently change rotations to complete persistent tasks. "

  Solar drones use solar energy as energy and store excess energy in batteries during the day. At night, fly continuously through the battery. "Compared with aircraft powered by chemical fuels, solar-powered aircraft does not pollute the atmosphere, and it is a truly green aircraft and an important direction for the development of drones in the future." Shi Wen said.

  China, the solar flight "club", finally occupies a place.

  In 1917, the British successfully developed the world’s first unmanned aerial vehicle (UAV), which opened the prelude to the development and innovation of UAV in the world. Today, solar-powered aircraft has become the forefront of the development of aviation science in the world, and it is an important field of technology and industry competition in all countries of the world. The development is in the ascendant, the results are one after another, and the competition is fierce.

  The development of solar aircraft in the United States started earlier. In 1980, the solar aircraft project was included in the national plan, and solar aircraft such as Pathfinder and Sun God were successively developed. As a leading country in the development of solar-powered aircraft, in 2007, the British Breeze UAV flew in the air for 54 hours with a flying height of over 15,000 meters.

  Without adding any fuel and emitting any pollutants, the Swiss "Sunshine Power 2" solar plane, which achieved the feat of flying around the world, has attracted much attention. "Sunshine Power 2" is mainly made of carbon fiber and weighs only 2,300 kilograms, which is equivalent to a small car. During the round-the-world flight in 2015-2016, it reached a maximum of 118 hours of uninterrupted flight, which is one of the important achievements in the development of solar aircraft in the world.

  As an aircraft developed all over the world, the reason why countries are willing to invest huge sums of money and human resources is that as a cutting-edge technology product, its technology and integrated industry’s driving ability are quite strong, besides its broad application prospects.

  "The solar drone project involves many technical fields such as aerodynamics, structure and energy storage battery. At present, its key technology is still a difficult problem in the development of the world aviation industry, and there are many technical gaps." Li Guangjia told reporters that in the field of solar-powered aircraft development, China started late, but it is unique. The aircraft represented by Rainbow Solar UAV entered the adjacent space, demonstrating China’s ambition to occupy a place in this field.

  Rainbow has a high starting point and stood at the forefront of aviation as soon as it was born.

  "Rainbow starts high, one ‘ Born ’ I stood at the forefront of aviation. " Through the innovative product Rainbow Solar UAV, the technical team of China has solved key technical problems such as overall, aerodynamics, flight control and efficient application of energy and power.

  Jia Yongqing, deputy chief engineer of Rainbow UAV Technology Co., Ltd., a research institute of China Aerospace Science and Technology Corporation, which is the research unit of Rainbow Solar UAV, said that the development of aviation technology should not be "born behind". Although the Rainbow Solar UAV started from "a blank sheet of paper", it was in line with the most advanced level in the world from the beginning.

  Any scientific research progress is not smooth sailing. In 2013-2014, the development of Rainbow Solar UAV also encountered great challenges: the aircraft often "jumped up and down, swayed left and right" when flying in low altitude and strong turbulence. In order to solve this problem, the research team tackled the problem hard. In theory and engineering, it took more than a year to solve the problem of precise control of the UAV under complex meteorological conditions, which not only made the aircraft fly, but also flew steadily and high.

  "At the same time, relevant researchers have gradually established and improved the design and test scheme of solar-powered aircraft by implementing the concept research of UAV platform and the development of small-scale verification machine, key technology research and scheme demonstration, and low-altitude and high-altitude flight tests of large-scale technical verification machine with a wingspan of more than 40 meters." Jia Yongqing said.

  "Relying on the Rainbow solar drone and other projects, and supporting the development of high-strength lightweight graphene new materials, new solar cells, new energy storage methods and other technologies and products will help to further promote the development of China’s aviation industry." Shi Wen said that in the future, China’s solar drones will also develop in the direction of ultra-high altitude, ultra-long endurance, large-scale and practicality, and the prospects are worth looking forward to.

  Data Relay, Aerial Surveillance, Emergency Communication … … Rainbow has a bright future.

  The ultimate goal of scientific and technological progress is to serve mankind. Only by finding the right application market can we have the foundation and potential for sustainable development. Innovative products like Rainbow Solar UAV "aim" at the application needs of economic and social development and can provide multifunctional technical services and products.

  According to the development plan, Rainbow Solar UAV will have the characteristics of "quasi-satellite" in the future. As an aerial platform, it will provide lasting data relay and 4G/5G communication, partially replace the communication satellite function, and realize uninterrupted situational awareness and relay communication service with full coverage of the region.

  For example, a great application prospect of Rainbow Solar UAV is to build an "airborne mobile WIFI" base station, which can provide more convenient, cheap and responsive mobile communication and Internet access services for remote areas or islands, avoid the huge construction, use and maintenance costs of traditional optical fiber or microwave transmission, and lower the information threshold.

  "From the perspective of extensive economic and social development, the field of solar drone service can also be extended to forest resources survey, agricultural survey, monitoring and forecasting of flood control, real-time assessment and rescue of major geological disasters." Shi Wen said that in the event of an earthquake, flood or forest fire, it can also replace the interrupted communication and maintain contact between the affected areas and the outside world.

Baidu World 2023 is a spoiler, and Baidu will release the first generative business intelligence product in China.

  Where is the biggest development opportunity in the era of big model? Basic service or industry service? Li Yanhong, founder, chairman and CEO of Baidu, believes that it is not, but in application. Among the 18 "catch-up rules for starting a business" published recently, Li Yanhong said that for entrepreneurs, the big model is meaningless and the application opportunities of the volume are greater. Baidu should be the first company to "reconstruct" all its products.

  On October 12th, Baidu held the "Baidu World 2023 Media Pre-communication Meeting", which revealed the latest development of network disk, intelligent work platform such as Streaming and Apollo Intelligent Cabin based on large model reconstruction. In addition, it is understood that at the "Baidu World 2023" held on October 17, Baidu will also release the first generative business intelligence product in China-Baidu GBI.

  The first generative business intelligence product in China

  In the business world, shopping malls are like battlefields, and enterprises compete, not the big fish eat small fish, but the fast fish eat the slow fish. If an enterprise wants to win, the most inseparable thing is business analysis. However, traditional BI tools are difficult to find data, use tools and have limited index coverage. Both Excel and data analysis platforms are designed for high-frequency (preset) scenes, so they can’t flexibly deal with various problems at any time. The analysis and insight of a complex problem often takes hours or days to complete. In the fierce and rapidly changing market competition, such a long decision-making cycle may lose important business opportunities.

  Sun Ke, Chairman of Baidu AI Cloud Technical Committee and Chief Architect of Baidu AI Cloud Application Products Center, said that Baidu GBI, which will be released on October 17th, can shorten the data analysis from days to minutes.

Baidu GBI

  First of all, traditional BI can only be operated by professionals, while GBI can directly understand the president’s question, implement it in real time, and draw conclusions quickly. Secondly, GBI provides a convenient access mode, so that enterprises can access data, ask questions and analyze any data, and there is no need to manually analyze across databases and tables. Third, GBI also has the ability to learn, and enterprises can inject professional knowledge into the industry and make it an industry expert.

  Baidu’s network disk will be upgraded again, and everything in the video will be refined.

  "In the AI era, the network disk no longer focuses on file transfer or storage," said Wu Tianhao, general manager of Baidu AI Cloud Network Disk Products Department. "Instead, it further moves towards knowledge management of individuals and enterprises, and realizes the transformation of information from data to knowledge."

  In the past 11 years, Baidu’s network disk has served 800 million users, and users will upload more than 1 billion pictures every day. Therefore, in the direction of AI reconstruction, Baidu’s network disk focuses on the intelligent service of personal files.

  "One Cloud" is Baidu’s first domestic network disk intelligent assistant based on Wenxin model. It not only realizes the transformation from graphical interface interaction to natural language interaction, but also enhances multimodal information understanding. Users can operate files, pictures and videos in the network disk with only one sentence, which is convenient for users to "find things" in the network disk and video. It is worth mentioning that Baidu’s network disk "Cloud One" can also help users quickly understand the video content, refine the content focus from the video, add subtitles to the video, export all the subtitles to the manuscript, and even add the title of the manuscript, greatly improving the information understanding and communication efficiency.

  Recently, Baidu’s network disk also launched the "Cloud One File Assistant" which can be used on WeChat. By forwarding any WeChat official account article to Cloud One, it can "read" directly, and summarize and refine the main points within 10 seconds, so that users can get the "essence dry goods" in a short time.

  "A powerful video processing and understanding ability of Baidu Netdisk Cloud will also be shown to you at Baidu World Congress, so stay tuned," Wu Tianhao said.

  The gospel of migrant workers is to have a "super assistant" who understands you and is professional.

  At present, there are still many pain points in the online office of enterprises. How will the big model reshape intelligent work?

  "The big model is a great opportunity in the field of corporate office." He Wei, director of Baidu’s intelligent office platform department, said, "With ERNIE Bot’s blessing, Baidu’s intelligent work platform has reconstructed intelligent work based on AI’s original thinking, stimulating enterprise innovation and improving efficiency."

  He introduced the "super assistant" created by Ruliu, which has three characteristics: knowing you, professionalism and real-time companionship. It has been aroused at any time and anywhere, and has been applied in a wealth of office application scenarios.

Baidu ruliu super assistant

  During the execution of intelligent tasks, the super assistant evokes through natural language voice, and realizes one-step direct access to complex systems for scenes such as meeting reservation, vacation and poor travel. In the intelligent document processing scene, the super assistant can quickly find out the relevant documents according to the instructions, which doubles the efficiency of knowledge acquisition, and can also quickly consult, summarize and translate the documents on the Web side of the browser; In the high-frequency communication scenario, "IM intelligent summary" and "AI meeting insight" and "AI meeting minutes" can quickly refine the main points and generate structured minutes. The data shows that through the use of the AI conference insight function, the current reading volume of conference content has increased by 3.5 times.

  He Wei believes that "unlike the stronger tool attribute under the concept of assistant, super assistant can be competent for more complicated tasks, and at the same time will help you finish your work more actively, so that intelligent work can replace hard work." At the scene of the 2023 Baidu World Congress, the reconstructed new features such as streaming will be unveiled.

  Large-scale model reconstructed intelligent cockpit, which will be carried in the mass production of Extreme Yue 01.

  The big model not only reshapes thousands of industries, but also profoundly affects the automobile industry. When the large model is combined with the car cockpit, the car will become an automobile robot with EQ and IQ.

  Su Tan, general manager of the intelligent car business department of Baidu Intelligent Driving Group (IDG), said: In the era of big model, based on the idea of reconstruction, we have the opportunity to change the relationship between man and machine in the car cockpit into the relationship between man and virtual person. Based on the Wenxin model as the basic model, and the massive data accumulation of Baidu Apollo in millions of smart cars and different scenarios, the Apollo intelligent cabin model and intelligent cabin development tool chain are further enhanced.

Large model landing intelligent cockpit

  The intelligent emergence of large-scale models brings core abilities such as understanding, generation, reasoning and memory, so that the format of intelligent cockpit will be reconstructed, including interaction, development mode, architecture and user operation mode. The first thing to be reconstructed is the interaction between people and vehicles. From "imperative" to "conversational", the naturalness of interaction will be greatly improved. The improvement of interactive experience will also greatly improve the user experience of just-needed scenes such as in-car navigation and car use. At the same time, the demand for in-car entertainment and services will be further released, and the user’s usage scenarios will also be reconstructed. Baidu Apollo has built an exclusive large-scale model technology base for the car cockpit. Based on the Wenxin large model, it has enhanced the effect of the large model in the car cockpit and provided more anthropomorphic intelligent interaction, including improving the understanding in the cabin, adding multi-modal understanding, active interaction ability, dynamic recovery ability, response time optimization and other capacity building to meet the intelligent needs of users for the cockpit.

  In order to make the smart cockpit empowered by the big model land more quickly, Baidu Apollo has also reconstructed the technical route of the smart cockpit of the car, and the development mode of the native application of the car AI based on the big model is deeply integrated with the localization. Apollo streamlines and implements the intelligent cabin AI native application development paradigm, reduces costs and improves efficiency in the whole link, and helps the industry to explore. Automobile host manufacturers can independently develop their own brand models and application scenarios, and Apollo will also provide a reference for boutique in-vehicle native applications, and build a large number of commonly used plug-in scheduling capabilities for the cockpit ecological environment, greatly reducing the input costs of automobile host manufacturers.

  At present, the car voice products blessed by Baidu Apollo Intelligent Cabin Model have been mass-produced in models such as Extreme Yue 01, Cadillac Ruige, Buick E5, Geely Yinhe L7 and Geely Yinhe L6, and brands such as Geely Yinhe and Haval will soon be launched. Among them, Extreme Yue 01 is at the leading level among the mass-produced vehicles in the industry in terms of its core capabilities such as millisecond response, full-time wakeup-free interaction, multi-channel simultaneous interaction, and full-page seeing and speaking.

  The scale of users of Qian Fan’s large model platform has grown rapidly, covering more than 400 scenes.

  Baidu is reshaping its products with big models, so the next question for entrepreneurs and enterprises is, how to build AI native applications?

  Li Jingqiu, deputy general manager of Baidu AI Cloud AI platform, said at the communication meeting that Baidu has summarized these successful practical experiences into tools and methodologies, and deposited them on the world’s first one-stop large-scale model service platform "Qian Fan" to help entrepreneurs and enterprises build their own AI native applications with low cost and high efficiency.

Baidu AI Cloud Qian Fan large model platform

  Baidu AI Cloud continues to improve and upgrade the tool chain on the Qian Fan platform. At present, 41 data sets and 226 sets of high-quality Prompt templates are preset on the Qian Fan platform, so enterprises can quickly optimize the model effect according to their own business scenarios. The platform also manages 42 mainstream large models at home and abroad, providing Chinese enhancement, performance enhancement, context enhancement and other capabilities. Qian Fan platform provides an extremely stable training environment for the performance guarantee issues that corporate customers are concerned about. Under the conventional method, engineers spend 30%-40% of their time on fault tolerance and fault recovery. Now, the fault management mechanism of Baidu AI Cloud’s self-developed cluster networking makes the effective training time of the model reach more than 95%.

  Li Jingqiu, deputy general manager of Baidu AI Cloud AI platform, revealed at the communication meeting that the user scale of Qian Fan platform has increased rapidly since March. By the beginning of September, there were nearly tens of thousands of monthly enterprises on the platform of Baidu AI Cloud Qian Fan, covering more than 400 scenes in manufacturing, energy, transportation and other industries.

  "Around the accelerated landing of AI native applications, Qian Fan platform will release more new products at Baidu World 2023 on October 17." Li Jingqiu, deputy general manager of Baidu AI Cloud AI platform, said.
