Never die! 165,000 frames repaired, every frame is precious!

　　Two days ago, Observer Jun attended a special movie premiere.

　　It is special because this film is not a new film in the traditional sense.

　　It is an old classic that has been reborn with the help of new technology — —

　　The first black-and-white 4K restoration feature film "Never Gone Radio Wave" jointly produced by CCTV Video and China Film Archive.

Film premiere scene

　　At the premiere ceremony, a promotional film with restoration effect was played on the big screen, and the black-and-white picture changed from blurred black and white to clear color.

　　After watching it, Observer Jun suddenly understood why Tian Hua, a 93-year-old performance artist, was so excited at the opening ceremony of the Beijing International Film Festival:

　　"Too fresh! It’s so vivid ‘ Color ’ Teacher Sun Daolin is so handsome! This kind of shock can only be completely felt on the big screen. "

　　Knowing that the restored film will be released on October 6, I observed that Jun did one thing immediately after the premiere — — Find the small partners of the project repair team and "force" them to "confess". How did you repair the film so vividly?

　　How did you do it? Did you really use magic? Don’t worry, and listen to the observation gentleman to tell you in detail!

Repair the coloring process

　　4K power:

　　Repairing as old can rejuvenate you.

　　"Never Gone Radio Wave" was filmed in 1958. At that time, film was the original carrier of movies. Sixty-three years have passed, and after years of precipitation, this film has also left traces of time — —

　　Because of the age, there are many problems on the film, such as dust, dirt, mildew, fading, image jitter, scratches, flicker, noise, discoloration, blurring and so on. Therefore, it is necessary to adopt digital film restoration and processing technology to deal with them, so as to obtain higher image quality.

Damaged film specimen

　　The intention of restoration, on the one hand, is to "repair the old as the old". With the help of digital restoration technology, the lost image on the old film can be restored to the original "taste" of the film as much as possible.

　　On the other hand, it is to make old films "rejuvenate" and be able to enter the cinema again. The resolution of the original film is 5460*4250, but with the erosion of time, the quality of the film base will react chemically. Under the existing technical conditions, the resolution of 4K is an ideal state for film restoration.

　　Before 2017, the digital restoration of old movies in China mostly followed the 2K standard. The 4K resolution is based on the 2K resolution, which fully increases the picture information by 4 times.

　　Therefore, before the repair, each frame of the picture must be magnified by the repairman four times before the damage can be seen clearly.

The repairman checks the film.

　　For the more serious and complicated damage, it is even necessary to extract some materials, and after careful observation and analysis in the appraisal theater, further decide how to repair it and what software to use.

　　For some special damaged pictures, the repairman must transfer the single frame of the picture to the later special effects software, and use the special effects function to realize 4K repair, restore the original flavor of the film, and restore the new life if it is old.

　　Triple repair:

　　What is the experience of clicking the mouse 20 thousand times a day?

　　The restoration of classic movies is generally divided into three stages: physical restoration, digital restoration and artistic restoration. The first two can be classified as technical repair.

　　The so-called physical restoration, the main task is to remove impurities from the picture, restore the visual texture of the picture at the beginning of production, and bring more comfortable and clearer visual experience to the audience.

　　Friends can refer to the movie One Second, where the projectionist played by Fan Wei washes and repairs the film by hand.

Film One Second hand-washed film screen

　　The original wrinkled film can be clearly shown again after proper scrubbing and drying. However, in the film, the copy volume was repaired, and this time, "Never Gone Radio Wave" repaired the original film background.

　　Digital restoration is to digitize the film, which is the largest stage of the whole restoration process. As mentioned in the previous part, after the film is digitally scanned, 4K digital restoration technology is used to deal with various problems such as mildew, fading, image jitter, scratches, flicker, noise, discoloration and blur frame by frame.

Scanning film

　　Each restorer clicks the mouse at least 20 thousand times a day. From this point of view, film restoration needs patience and professionalism.

　　The repair time of a frame is as short as a few seconds, and as long as several hours or even days. The total duration of "Never Gone Radio Wave" is 116 minutes, and the whole film has 165,000 frames. With such a huge amount of work, people who can persist must have a heart that loves movies.

　　Film restoration is a technical activity, which also needs creative aesthetics. When the physical restoration and digital restoration are over, the film restoration will reach a higher level — — Art restoration.

　　That is, follow the principle of "repairing the old as before" and try to restore the film to the maximum extent.

　　Specifically: the granularity of the film picture, the tone of the film with a sense of time, the color of clothes, the shadow of tables and chairs, the color of people’s skin, the depth of field of the lens and so on.

　　Every place should be reproduced in combination with the original style of the old movie. The person who knows this film best is the creator of that year. To this end, the project restoration team invited the film’s creative staff to the scene as much as possible to guide, try to find the director and photographer at that time, follow their ideas, and determine the restoration standards.

Comparison before and after repair

　　Black and white to color:

　　In addition to AI, there is more ingenious "color archaeology"

　　"Never Gone Radio Wave" was originally a black-and-white film. To achieve complete restoration, it is necessary to convert the black-and-white image into a color image through AI and artificial coloring technology after completing the triple restoration.

Comparison before and after repair

　　This time, the restoration team combined the human-computer interactive AI coloring with independent intellectual property rights in China with traditional restoration techniques to restore and color the original black-and-white image of the film frame by frame.

　　AI has greatly improved the overall work efficiency, but the soul of repair still needs artificial ingenuity. Because there are so many complex elements in focus plane, the current AI technology has limited ability to identify complex objects, and it is often impossible to track the details of moving side face and hand shape changes. At this time, it is necessary to manually solve them frame by frame.

Comparison between AI and artificial coloring effect

　　In order to make the color of the film more accurate and appropriate, the project restoration team composed of Central Video and Film Archive also launched a large-scale "color archaeology".

　　In the film, Bai Lijun, the liaison officer of the underground party, was waiting for the elevator in the Peace Hotel. The lens hurriedly swept a decoration, and the material could not be seen in the black and white environment. The repair team specially contacted Shanghai Peace Hotel and finally determined that it should be the color of blue and white porcelain.

　　In order to determine the color of the cheongsam that appears many times in the film, the team specially visited the non-genetic inheritor of the traditional cheongsam in China, and judged the color through the material, lightness and technology, thus giving the cheongsam of the female role in the film a three-dimensional sense, gloss and texture again.

Refer to a large number of cheongsam materials

　　In order to verify the cover color of the thread-bound book A Dream of Red Mansions, which was used by the leading actor Li Xia to transmit information, the team specially invited experts from the Dream of Red Mansions Society, and finally decided that the cover should be the light blue cover of the lead-printed book at that time.

Experts analyze the cover color of A Dream of Red Mansions in the film

　　In order to color the lips of female characters in the film, the team studied in detail the brightness differences of reddish, vermilion and crimson in black and white pictures, comprehensively considered the role identity and character characteristics, and matched female characters in different camps and stages with bright or elegant colors.

Consider the characteristics of female roles

　　Rebuilding "hearing":

　　5.1 surround sound, to achieve real sound immersive.

　　When the picture is upgraded to 4K, the sound quality will naturally be repaired simultaneously to meet the current cinema screening standards.

　　Generally speaking, movies divide sounds into five categories: dialogue, environmental atmosphere, special effects, onomatopoeia and music. The project repair team must first separate all kinds of sounds, then remove the noise, and then re-complete the mixing recording according to the sound phase of the picture.

Sound restoration process

　　At the same time, according to the picture, the ambient sound is supplemented to enrich the indoor ambient sound, so that the hearing is more telepresence, and the sound is used to supplement the picture for the second time, adding some human voice environmental effects.

　　In the end, the black-and-white to color 4K restoration version of "Never Gone Radio Wave" was converted from the original stereo to 5.1 surround sound.

　　When watching in the cinema, we will feel a more realistic sound field, and we can appreciate the soul-stirring of the hidden front in the revolutionary era.

　　As the first film in New China about the hero of the Party’s hidden front, The Never-Gone Radio Wave is almost the "model" of all the domestic spy films.

　　Li Xia, played by Mr. Sun Daolin, has influenced generations of Chinese with his image of Communist party member, which is optimistic, resolute, fearless and courageous.

　　Good movies and true heroes should not and cannot be buried by time and space.

Sun Daolin plays Li Xia.

　　Although film restoration doesn’t need high-intensity and orderly cooperation like shooting on the set, it still needs a clear division of labor and seamless cooperation.

　　The project restoration team dispatched hundreds of people before and after, and it took seven months to finally complete the restoration of 165,000 black-and-white images of Never Died Radio.

　　Chunhua Qiushi, staying up late again and again, comparing frame by frame, and making a little adjustment, finally handed over this answer sheet with renewed vitality.

Repair the coloring process

　　Every frame, every second, is a tribute to the hero and a call for fine works of art.

　　On October 6th, in the golden autumn season, Observer Jun invited you to walk into the cinema together to see the brand-new scenery of this red classic!

Do you know about World Statistics Day？

　　　　　　　 In 2010, the 90th meeting of the 64th UN General Assembly adopted a formal resolution to designate October 20th, 2010 as "World Statistics Day". This is the first global statistics day in history, and global statisticians have ushered in their own common festival. Five years later, the 69th United Nations General Assembly officially designated October 20th as World Statistics Day, which is celebrated every five years. As a grand event that transcends national boundaries, World Statistics Day highlights the concept of "global statistics are one" and enhances the importance of official statistics and public recognition.

　　　　　　　 I. Origin of "World Statistics Day"

　　　　　　　 After the end of World War II, all countries are healing the wounds of war and restoring and developing their economies. In this process, official statistics began to play a role in social and government decision-making, especially in important areas of people’s livelihood such as economy, population and health. With the continuous development and progress of economy and society, the national statistical agency responsible for producing and disseminating official statistical data has become one of the important national institutions in every country, and statistical data has also become an important basis for government decision-making, academic research and public knowledge.

　　　　　　　 Worldwide, the United Nations established the Statistical Commission in 1947, which is responsible for formulating international statistical standards, methods and guidelines, and promoting the standardization and global comparability of statistics in all countries of the world, the improvement of methods and systems and the improvement of data quality. Nowadays, global statisticians cooperate sincerely, and official statistics have formed a closely linked world family. Every year, heads of statistical agencies of United Nations member countries and international organizations gather in new york to make decisions on various statistical issues at the annual meeting of the United Nations Statistical Commission. Official statistics have made unprecedented achievements on a global scale, which deserves to be celebrated by the statistical community.

　　　　　　　 In September 2008, the United Nations Statistics Division invited countries, regional institutions and international organizations to express their views on the proposal to celebrate World Statistics Day on October 20, 2010. Although many countries and regions have held statistics day, statistics week or statistics month celebrations in various forms, global statistics day celebrations can better show the great achievements made by official statistics in the world and the important contributions made to economic and social development. This initiative received a wide response during the fortieth session of the United Nations Statistical Commission in February 2009, and 75 countries and international organizations expressed their support. Based on these positive feedbacks, the forty-first session of the United Nations Statistical Commission in February 2010 considered the report on World Statistics Day, and at the 64th session of the United Nations General Assembly, a resolution was made to designate October 20, 2010 as World Statistics Day, inviting governments to support the celebration of World Statistics Day.

　　　　　　　 Second, the style of previous World Statistics Days

　　　　　　　 On October 20th, 2010, the United Nations Department of Economic and Social Affairs and the National Bureau of Statistics of China jointly held the first global celebration of "World Statistics Day" in the United Nations Pavilion of the Shanghai World Expo, with the theme of celebrating many achievements of official statistics and promoting the core values of "service, integrity and professionalism" of official statistics, aiming at enhancing public understanding and support for official statistics. Li Keqiang, Deputy Prime Minister of the State Council, China, and Ban Ki-moon, Secretary-General of the United Nations, sent written speeches; The Statistics Department of the United Nations Department of Economic and Social Affairs and the National Bureau of Statistics of China jointly held the launching ceremony of "World Women: 2010" and "Interpretation of Main Statistical Indicators in China", signed the Letter of Intent on International Statistical Training Cooperation between the National Bureau of Statistics of People’s Republic of China (PRC) and the United Nations Statistics Department, and held the opening ceremony of the China International Statistical Training Center-United Nations Statistical Cooperation Center. The celebration of the first World Statistics Day was supported and promoted by about 80 countries around the world, and more than 100 countries around the world held celebrations.

　　　　　　　 On October 20, 2015, the second World Statistics Day was celebrated in Xi ‘an, China. Nearly 100 statistical officials, experts and scholars from 55 countries and international organizations gathered together to show government statistical achievements, share statistical development experience and advocate statistics to better serve economic and social development and enhance people’s well-being. The theme of this Statistics Day is "Optimizing Data and Improving Life", which has been supported and promoted by national statistical agencies, statistical associations, universities and other partners in more than 110 countries and regions around the world. Promotion activities include holding a press conference, reporting the latest survey or census results, and releasing statistics of interest to the general public, which further expands the influence of official statistics.

　　　　　　　 The third World Statistics Day was held on October 20th, 2020, with the theme of "Connecting the world with data we can trust", emphasizing the importance of credibility, authoritative data, innovation and public products in the national statistical system. The celebration was organized under the guidance of the United Nations Statistical Commission, and the global statistical agencies made joint efforts to hold various activities to display and publicize statistics. In his invitation letter to all countries, UN Secretary-General Antonio Guterres pointed out: "On the occasion of the 75th anniversary of the founding of the United Nations, the whole world is deploying data to meet common challenges. Let us take the opportunity of World Statistics Day to highlight the important role of statistics in promoting sustainable development."

　　　　　　　 Third, China Statistics Open Day

　　　　　　　 The National Bureau of Statistics of China responded positively to the United Nations resolution on celebrating World Statistics Day, and designated September 20th, 2010 as "China Statistics Open Day", and carried out a series of activities with the themes of "Statistics with You" and "Towards Open and Transparent China Statistics". Since then, in mid-September every year, the National Bureau of Statistics will hold a series of activities of the China Statistics Open Day in combination with the major themes and key work of China’s official statistics in that year, and invite grassroots statistical investigators, users of statistical data, teachers and students of colleges and universities, netizens and media reporters and other representatives from all walks of life to the event site for discussion and exchange, so as to enhance the public’s understanding of statistical work and statistical data and promote China statistics to be more open, transparent and better serve the society.

　　So far, the National Bureau of Statistics has heldThe 11th China Statistics Open Day received great attention from all walks of life, the active participation of the public, and the strong support of statistical institutions at all levels and statisticians. It not only showed the new achievements of China’s statistical reform and development, but also spread statistical knowledge and promoted statistical culture.

　　"We are worried that the riders will not be willing to send the food to the college students because they earn less. We are also worried that if there is a problem with the food, the riders from both sides will pass the buck to each other. We don’t know who to complain to," one student told reporters.

Some students at Shanghai Jiaotong University told reporters that the response could be checked on the official forum of the school, and the source was "Security Department".

　　The school security office said that after seeing the questions raised by everyone, it immediately contacted the school teaching service group (Shanghai Jiaotong University Education Service Industry Investment Management (Group) Co., Ltd., which belongs to Zhenxing Education Service Industry Co., Ltd.) to feedback the students’ opinions and communicate to confirm relevant matters.

　　Its response said that the purpose of implementing the campus delivery team is to reduce the traffic accidents caused by the campus delivery electric vehicles under the premise of ensuring that the delivery quality assurance of teachers and students on campus is delivered to the buildings and teachers and students on campus, and to file and review the identity of riders entering the school in advance to ensure campus safety to a greater extent. "Before the delivery, there have always been problems such as uneven personnel quality, high mobility, mostly self-employed, and difficult supervision. If the delivery staff is self-employed, it is difficult to safeguard the rights and interests of teachers and students after a traffic accident. Therefore, the Security Department wants to urge the delivery platform to establish a campus delivery team, and the campus delivery team is uniformly managed by the delivery company."

　　Regarding the questioning of the compliance of Shanghai Jiaotong University Zhenxing Education Service Industry Co., Ltd. in charge of campus takeaway delivery services, it responded that in the early stage, the takeaway platform service providers were openly selected, and the campus delivery team was established according to the requirements through the selected platform. The takeaway platforms that participated in the selection and passed the selection were Ele.me, Meituan, Domino’s, and Jingle Zhiyao. In the later stage of the campus delivery team construction, the Ele.me and Meituan delivery platforms chose to connect with the school teaching service group and reach a cooperation agreement according to the actual operation situation. Shanghai Jiaotong University Zhenxing Education Service Industry Co., Ltd. affiliated to the teaching service group was responsible for the campus takeaway delivery service and established a campus takeaway delivery team.

　　Tianyancha shows that Shanghai Jiaotong University Zhenxing Education Service Industry Co., Ltd. was established in February 1993. The registered place is located in Xuhui District, Shanghai. The legal representative is Guo Xiaoqing. The registered capital and paid-in capital are 1 million RMB. On May 7, 2020, the company added express services to its business scope. The company is 100% controlled by Shanghai Jiaotong University Education Service Industry Investment Management (Group) Co., Ltd., and the actual controller is Shanghai Jiao Tong University.

　　"This is a cooperation agreement between the takeaway delivery platform and the relevant companies according to their own considerations and choices. There is no process that requires on-campus invite tenders. And Shanghai Jiaotong University Zhenxing Education Service Industry Co., Ltd. is also responsible for the on-campus express delivery business. They have both on-campus takeaway delivery teams and on-campus express delivery teams. These two teams can complement each other to ensure takeaway delivery during peak periods in the school." The Security Office replied.

　　Rider: If you pay the fee to the Jiaotong University transfer station again, or consider "transfer order"

　　The school security office also replied to the question of whether and why the 2.5 yuan that students are concerned about should be charged to the takeaway staff. It learned from Shanghai Jiaotong University Zhenxing Education Service Industry Co., Ltd. and the third-party distribution platform that the total delivery fee from merchants to dormitories in the Minhang campus of Jiaotong University is currently 4 to 5 yuan. The delivery platform promises not to increase the cost of teachers and students ordering takeout due to the adjustment of the delivery mechanism. During the practice run, the delivery platform extracts 2 yuan to 2.5 yuan per order for takeout delivery on campus according to factors such as distance, of which the delivery platform reserves about 1 yuan per order. According to the cooperation agreement reached between the delivery platform and Zhenxing Company, the remaining 1 yuan per order is the cost of Zhenxing Company responsible for on-campus takeout delivery. At present, in order to provide good service to the students, Zhenxing Company has almost given this part of the fee to the riders who are specifically distributed on campus.

　　What do riders and merchants think about this?

　　At noon on August 14, the surging news reporter saw at the Arc de Triomphe of Shanghai Jiaotong University that although it was summer vacation, there were still a lot of takeaways. Around 12:30 noon, there were seven or eight takeaway riders in ten minutes, most of whom were Ele.me.

　　On the same day, the reporter stopped the riders at the entrance of the Arc de Triomphe of Shanghai Jiaotong University and near the Longhu Tianjie shopping mall near the school, and learned that most of them had heard about the new measures for takeaway admission to the school from September 1. According to multiple riders, they received the news that each Ele.me rider needs to pay 2.5 yuan/order at the transfer station, and Meituan riders pay 3 yuan/order.

　　Xiao Deng, an Ele.me rider, told reporters that he heard the news as early as about half a month ago, "when he saw the relevant notice outside the North Gate of the school." Xiao Deng said that he has delivered takeout to Shanghai Jiaotong University for about two years. Usually, the main order comes from this university. After the start of school, an average of 20 to 30 takeout orders can be delivered a day. Xiao Deng said that he now earns about 4 to 5 yuan for each takeout order, and suddenly pays half of the fee, which is very reluctant.

　　When asked by reporters whether the implementation of the riders’ new measures would affect their willingness to take orders, many riders said that it would indeed have an impact. "If you encounter a list of students from Shanghai Jiaotong University, you will consider transferring it to others, but there is also a limit to the number of times we can transfer it in a day. After all, if the money is less, who will do it?" Two other riders told reporters that in the future, orders on the campus of Shanghai Jiaotong University may be considered more for crowdsourced riders.

　　The reporter then went to the merchants at the school gate as a student to understand the situation. Some business owners said "I don’t know, I don’t really believe this will happen", and some merchants said they had been notified, and their future expenses did not increase.

　　On the afternoon of the same day, the reporter saw at the east gate of Shanghai Jiaotong University Minhang Campus that the transfer station had been set up, and the QR code for the communication group chat during the transition period was hung outside the door.

　　The battle for takeout into the school: Some students have complained about safety hazards, and the measures have been adjusted several times

　　A rider told reporters that just across the street from the Minhang campus of Shanghai Jiaotong University, East China Normal University has been placing takeaway food at the school gate for many years, "but their school gate is relatively close to the accommodation area, Jiaotong University is indeed too big, and it is too far from the school gate to the dormitory." The reporter’s inquiry found that the issue of takeaway food entering the school has indeed caused controversy at Shanghai Jiaotong University. In May 2023, a student posted on the school’s internal forum that "the takeaway rider in the school almost killed me".

　　Over the years, the measures taken by the Security Department to bring food into Shanghai Jiaotong University have also undergone several adjustments.

"Ping An Jiaotong University" tweet on November 2, 2017 Source: Ping An Jiaotong University WeChat official account

　　The reporter inquired about the WeChat official account of the Shanghai Jiao Tong University Security Department "Ping An Jiaotong University" and found that on November 1, 2017, at the special meeting on takeaway distribution management jointly held by the Jiaotong University Security Department and the East China Division Security Department, Yang Lizhi, the captain of the campus guard of the Shanghai Jiaotong University Security Department, pointed out that the management of campus takeaway delivery speeding, illegal riding, and uncivilized driving will be more standardized and effective. The meeting invited the heads of the surrounding takeaway stores to participate, and reached an agreement with the merchants. The two sides will use the Mi U App software to sell cars externally for real-time management.

　　The meeting clarified that the secret service and security teams implement identity authentication management measures for food delivery personnel, and they can only enter the school if they meet the qualifications. The staff of the Security Department and the person in charge of the store can open the location of the food delivery personnel through the Mi U App software to keep abreast of the speed of cars sold inside and outside the school, including normal driving, faster driving, and speeding vehicles. The speed limit on campus is 20km/h. Combined with real-time monitoring data, measures such as warnings and deductions are taken for speeding vehicles, and the food delivery qualification will be cancelled after deducting 10 points.

　　During the epidemic, the admission regulations of Shanghai Jiaotong University have changed according to the epidemic situation. On February 10, 2023, the WeChat official account of "Ping An Jiaotong University" issued an article saying that students’ relatives and friends can enter the school, but takeout will not be allowed to enter the school for the time being; on March 3 of the same year, the above official account issued an article saying that from now on, regular takeout staff can enter the Minhang campus for food delivery, and all takeout staff entering the school must dress properly and drive at a limited speed. Unlicensed takeout staff are strictly prohibited from entering the school. "For reasons of safety and unified management, only professional campus delivery team takeout staff designated by Meituan and Ele.me are allowed to enter the school to deliver takeout. For other takeout staff, it is not open yet. This campus takeout access has not charged any deposit or other fees to any takeout staff or delivery team."

Brother Yang’s account has over 100 million fans, surpassing Simba to become the first brother of Internet celebrities

Finally! In November 2022, some time ago claimed that the number of fans is about to break 100 million of the well-known Internet celebrity crazy little brother Yang’s personal fans broke through 99.99 million +, surpassed the Internet celebrity Simba, became the first Internet celebrity circle fans broke 100 million Internet celebrity live streaming host.

As a rising star, Crazy Little Brother Yang can surpass Simba and break through 100 million first, which is still very surprising. Some netizens have questions about why he is so popular. However, it is reasonable for Crazy Little Brother Yang to break through 100 million fans. As one of the most down-to-earth Internet celebrity live streaming hosts, from obscurity to popularity to the current fan breakthrough 99.99 million +, Crazy Little Brother Yang and Big Brother Yang have not forgotten their original intentions, which is very admirable.

The Crazy Little Brother Yang account was mainly "operated" by twin brother Zhang Qingyang and Big Brother Zhang Kaiyang in 1995. The 27-year-old brothers were worth far more than their peers.

From a prank roommate to a prank girlfriend to a prank parent, Crazy Little Brother Yang spent six years figuring out a set of traffic passwords – that is, the plot reversal of funny first. After starting to bring goods, Little Brother Yang also brought this "characteristic" to the live stream. The plot display without creative bottlenecks made fans laugh, and the number of fans also rose.

Since the beginning of this year, the speed of crazy little brother Yang’s increase in fans has made him "afraid". Now the total number of fans of Douyin has exceeded Andy Lau by nearly 20 million, and the personal ranking is first. After the suspension of the broadcast for two months in June this year, the return "debut" is also very popular. Go LIVE only 10 minutes, and the number of likes has reached 170 million. Feeling the pressure, little brother Yang reduced the live broadcast time, turning the original live broadcast three times a week into two live broadcasts every Tuesday and Saturday.

According to the data of Mother Cicada, in the ranking of experts on the Douyin Moon List, Crazy Little Brother Yang ranks second, followed by Brother Yi and Make a Friend who have recently exploded.

Although Crazy Brother Yang was nearly half of the sales from the first-place Dongfang Selection, the number of live broadcasts was one-third of the number of Dongfang Selection. In other words, if Brother Yang did not reduce the number of live broadcasts, or the same frequency as Dongfang Selection’s live broadcast, his GMV would definitely rank first.

The continuous explosion has also made everyone’s supervision of Brother Yang more and more intense, so Brother Yang’s live stream is often reported by netizens. Some fans shouted that Brother Yang should pay his taxes on time during the live stream, and some netizens corrected his live stream that there should be less sexy and beautiful women suspected of rubbing the edge. Even Douyin officials are highly concerned about it. On April 8, Brother Yang was forced to go off the air by the official for saying sensitive words in the live stream.

In any case, or once again bless the crazy little Yang fans to break through 99.99 million +, become the first person in the Internet celebrity world, I hope that the little Yang brother can bring more joy to everyone in the future, and I hope that the little Yang brother has better development and results in the live streaming industry.

The spring of artificial intelligence creation has come, and the ＂hidden rules＂ of ancient poetry are taught by computer.

　　Xinhua News Agency, Beijing, March 12th Special feature: The spring of artificial intelligence creation is coming.

　　Xinhua News Agency reporter Peng Qian Liu Si

　　"Early spring rain Chu Qing, willow filar silk caught the shore warbler. The painting boat is full of smoke and waves, and the small bridge is light. "

　　Who would have thought that this is a poem created by artificial intelligence with "early spring" as the key word. The author "Nine Songs" was developed by a student team led by Professor Sun Maosong of Tsinghua University Computer Science and Technology Department for three years.

　　Xiao Bing, Microsoft’s chat robot, "narrowly beat" human opponents with a Chinese-style song "Peach Blossom Dream" in the variety show "Wit". When the singer sings such an archaic sentence as "In the boundless night rain, the past is like the wind, the peach blossoms in the ear laugh at the spring breeze, and you and I meet in the dream", many viewers think that this is made by human beings.

　　The spring of writing poetry, composing music, painting and artificial intelligence has come quietly … …

　　Technically, "familiar with 300 Tang poems"

　　Zhou Ming, vice president of Microsoft Asia Research Institute, is a literary lover. He and the research team taught Xiao Bing to write modern poetry, and composing music is a new skill.

　　Zhou Ming said that neural machine translation, chatting robot, reading comprehension and creation are the four main aspects of the application of natural language processing technology, and the difficulty is gradually increasing. Creation is at the top of the pyramid and it is the most difficult to break through.

　　"In the beginning, people couldn’t find how to model creation because it was emotional. Writing poems and writing lyrics are all things with flying literary talents and sudden inspiration, which are difficult to capture. " He said. Thanks to the progress of deep learning and neural network technology in recent years, artificial intelligence creation has won many brilliant achievements.

　　Zhou Ming introduced that writing songs by Xiao Bing is a process of "encoding and decoding". The researchers first trained artificial intelligence robots with popular songs. After sufficient training, you can start writing: after inputting the song theme in the form of keywords, it will be coded into a language that artificial intelligence can understand, and the robot will decode and output it in a way that people can understand, becoming a lyric; Then combine this word with the original keyword as a new input, and you can get the second sentence, and so on to get the whole song word. Similarly, you can also input lyrics and translate them into music scores, that is, you can regard music scores as natural languages, thus completing computer lyrics and music scores.

　　"Nine Songs" learning to write poetry is also "familiar with 300 Tang poems, and you can recite them even if you can’t write poetry".

　　Yi Xiaoyuan, the founder of "Nine Songs" and a graduate student in Tsinghua University, has input more than 300,000 ancient poems since the Tang Dynasty as a corpus, and used the deep learning model to make computer learning. In addition to the rules for leveling and rhyming poems, no artificial rules are given, but computers are allowed to learn the "hidden rules" in ancient poems themselves.

　　"We don’t know the rules of how computers make such poems," said Sun Maosong, which is a "black box" phenomenon of deep learning. In his view, each ancient poem is like a necklace, and the beads on the necklace are words. In the deep learning model, the necklace is completely broken up, and then the implicit association between each bead and other beads is given different weights through automatic learning. When writing a poem, put different beads back into a new necklace.

　　The ancients wrote poems mostly to express their feelings, and the style was sad, which also made the poems written by "Nine Songs" somewhat "sad for spring and autumn". The team hopes to make the "Nine Songs" more positive by strengthening the training of some relaxed emotional samples. In addition, how to write a longer poem on the basis of ensuring the consistency of the whole poem is also a new challenge.

　　In artistic conception, "Kung Fu is beyond poetry"

　　In addition to writing poems and composing music, artificial intelligence has evolved new skills such as writing novels and painting. The science fiction novel "The Day when a Computer Writes a Novel" created by artificial intelligence developed in Japan deceived all human judges and was successfully shortlisted for the Japanese Fiction Literature Award. Google artificial intelligence can also create paintings, and some paintings have been sold at a high price of $8,000.

　　Artificial intelligence has defeated human beings in the fields of chess and cards, video games, etc. Does the latest progress in the field of artistic creation mean that it is not far from surpassing human beings in this respect?

　　Zhou Ming believes that at present, artificial intelligence creation is only based on the imitation of big data, which is far from the creative intelligence of real human beings. "There is not enough data for training artificial intelligence creation, such as the data for composing lyrics; Secondly, the inspiration is not enough, because the data alone is just a follower, writing words and composing music are familiar, and there is no feeling of sudden inspiration in generate. "

　　In Sun Maosong’s view, at present, artificial intelligence creation is a limited creativity, which theoretically does not exceed the creative space unconsciously defined by predecessors in the practice of poetry creation for thousands of years. The ancients wrote poetry as "Kung Fu is beyond poetry", often based on experience, with content and artistic conception, but it is difficult for machines to "express their aspirations" or "express their feelings through scenery" for the time being.

　　Experts believe that the fear that artificial intelligence surpasses human beings in the field of creation is alarmist. "In areas that need deep connotation or inspiration, such as music creation, poetry and prose, I personally think that machines are basically unlikely to reach the state of people, but they will assist people’s creation." Zhou Ming said.

　　However, artificial intelligence can improve the efficiency of professional creators. "If you can’t think of using a word when writing, artificial intelligence will think of a word for you and let you find that you can write like this." For ordinary people, artificial intelligence creation systems such as "Nine Songs" can lower the threshold of creation and realize the dream that "everyone can be a poet, painter or musician".

　　Sun Maosong said that the team plans to upgrade the "Nine Songs" system in the future, so that it can judge the quality of people’s poems, such as whether there are mistakes in rhyme and level tone, whether words are unsatisfactory or sentences are incomplete, and help people improve their creative skills; You can also conduct "humanistic calculation" and quantitative analysis and research on ancient documents through big data.

　　In addition to the creation itself, the study of machine creation can also bring unexpected benefits to other fields of artificial intelligence, and open up innovation in many fields and interdisciplinary subjects.

　　"Before letting Xiao Bing learn music creation, we never thought that music can also be processed by natural language technology," Zhou Ming said. "So once the natural language breaks through, it can drive the breakthrough of cognitive intelligence and the whole artificial intelligence, and there will be many scenes that were unimaginable before."

Computer seal engraving is easy to counterfeit. Hand seal engraving is on the verge of extinction (Figure)

Computer engraving is popular, and the business of seal carvers is slow.

　　This newspaper (reporter Shi Shanwei photographed Qin Yang) only needs a carving knife to put the names, flowers, birds, insects and fish into the square inch. Xiang Songqiu, who lives in Laoxiguan, Guangzhou, has been in business for 50 years for three generations. Although he is famous far and near, he can’t get a single business in January. Computer engraving is all over the street, and a seal can be done in one minute, which is convenient and at the same time, it also makes the fake official seal flood and hard to prevent. Manual seal cutting is unrepeatable, but few people care about it, and this traditional craft is facing extinction.

　　Fifty years into the business, carving official seals to become famous.

　　In Heping West Road, Liwan District, I saw a sign of "Autumn Carving" on the roadside. Walking up the narrow staircase to the second floor is Xiang Songqiu’s living room, and a wooden table in the corner is his workbench.

　　Xiang Songqiu, 63, is the third generation descendant of Xiang Jia’s seal cutting, and Yin Chuang, the wooden table, was handed down by his ancestors. His uncle Xiang Xinnan was a famous stone engraver in Guangxu period of Qing Dynasty, and his father Xiang Shaonan was also a minor famous stone engraver. He worked as an artist for more than 80 years and carved seals for many celebrities and politicians. Xiang Songqiu entered the Red Seal Engraving Factory in Guangzhou on January 1, 1960, and has been in the business for 50 years.

　　"Horn, ivory, jade, pear wood, boxwood, pen wood … all can be used for engraving, but different materials need different carving knives." Talking about this craft, Xiang Songqiu gushed.

　　Not only is Xiang Songqiu well-known in the industry, but he has also been interviewed by many English media, and the British and German consuls in Guangzhou have also come to him to carve seals. Compared with his predecessors, he also carved the zodiac, flowers, birds, insects and fish into it when carving leisure chapters. Once a man asked all over Guangzhou to engrave his name in a painting, but his peers said that he could not engrave it. Finally, he found Master Xiang, and this seal became his masterpiece.

　　After 50 years in the business, Xiang Songqiu is best at carving official seals. Before the reform and opening up, many banks, police stations and other government departments in Guangzhou appointed him to engrave the seal. "The business of engraving can also reflect the ups and downs of the economy. The 1980 s was the golden age of engraving." Xiang Songqiu recalled that at most, he took over thousands of orders to engrave the company’s official seal in a month.

　　Computer engraving "encourages" fake official seal fraud

　　However, in the late 1990s, computer engraving began to rise because of its low price and high speed, which quickly occupied the market. Master Xiang’s business has plummeted, and now there are so many "autumn engravings" that he can’t get a single business for a month at the worst.

　　"Computer engraving is the same and easy to counterfeit." Xiang Songqiu said that the hand-carved chapter is unrepeatable, and the fake chapter can be known at a glance. Xiang Songqiu plans to cooperate with a computer engraving shop.
