1905 movie network news　Directed and produced by a rookie director, Peng plays Wang Xueming, whose otherwise uneventful life is transformed by a steamy summer night when the entire city loses power. Wang Xueming’s erratic choices embroil himself in a complex case that alters the fates of everyone in the story. In the exposed trailer, Peng Yuyan was ruthless without a word. The thinner image, dim eyes, and collapsed eye sockets all made the audience question "Is this Peng Yuyan?", and the raised vertebrae were completely eye-catching, which also made the audience suspicious. For this reason, Peng Yuyan said, "This scene took off a layer of skin."

Acting in a dehydrated state, Peng Yuyan can’t sleep at night due to self-depression　　

Peng Yuyan plays Wang Xueming in the film, who is depressed, gloomy, and inarticulate. He always keeps his hat down and hides in the crowd, like a hidden person who has no sense of existence. Director Wen Shipei compares him to a black fish, while Peng Yuyan himself is an extremely positive optimist. Whether in life or on the screen, he is familiar with the image of positive energy, and his reason for taking the role is always related to this – "I hope it can infect or inspire people who watch movies." This time, to play a role that is very different from his own personality, Peng Yuyan needs to maintain a depressed state during the two-month shooting period. He has cut off many ways to make himself happy and immersed himself in the character’s state through physical training, dietary restrictions, and emotional control.

"Wang Xueming is not a happy person. I want to be ready when I shoot every day, so I often jog in advance, consume myself to a certain extent, and act in a dehydrated state, which is more like." Peng Yuyan revealed that during the two months of filming, he often suffered from insomnia, which coincided with the character. "Wang Xueming often suffered from insomnia, so his state was not very good, and I myself could not sleep during that time. I think this is a signal of my self-control in physical, diet and psychological, which in turn helps me to get closer to the character."

Revealing the original intention of the play: I hope to find the courage to face myself squarely

Peng Yuyan said that his original intention for taking on the role of "Once Upon a Time in the Tropics" was that he wanted to seek a kind of courage to face setbacks, and this is exactly what Wang Xueming’s role can give him. "The first time I saw the script, the most intuitive feeling was that it was very powerful. I hope this role can give everyone and myself a kind of strength. When encountering difficulties or mistakes that I dare not face, I can have the courage to look directly and bear it, and then I can grow. This is my original intention for taking this role."　　

"The attraction of Wang Xueming’s character to me is that he is looking for redemption through this event. Everyone will live in the past, and some people dare not face it. Xueming wants to forget the past, but he has to face it." Peng Yuyan said that making the movie "Once Upon a Time in the Tropics" has made him grow a lot. "When you look directly at your fears and the past, you can face the sun. This is a story of character growth."

　　Introduction:As an evolved version, what is the difference between Xiaodu Home 1S and the previous generation product Xiaodu Home? You may wish to find out through the following table.

　　With the rise of the concept of smart home, smart speakers, known as the entrance to smart homes, have gradually emerged and become a hot product in the market. Recently, as a latecomer in the field of smart speakers, Baidu has once again made efforts to bring a new product to the majority of consumers – Xiaodu Home 1S.

　　According to the China Industry News, competitiveness and international cooperation are compulsory courses before a large aircraft "takes off."

　　On December 29, 2007, Premier Wen Jiabao made a special trip to Xi’an Aircraft Industry (Group) Co., Ltd. to inspect and welcome the 2008 New Year with Xifei people. Premier Wen pointed out that the independent development of large aircraft is a major strategic decision made by the Central Committee of the Communist Party of China and the State Council, which means that the Chinese people will use their own hands and wisdom to create a competitive large aircraft in the world.

　　What is competitiveness? It is to achieve mass production and achieve the three important goals of safety, economy and comfort, so as to be competitive in the domestic and international markets. The large aircraft that Premier Wen refers to as competitive in the world refers to the civilian passenger aircraft (hereinafter referred to as the large aircraft) in China’s large aircraft.

　　What kind of big aircraft does our country want to build? Industry insiders pointed out that we must first start with the nature, market, model, range and non-large regional passenger aircraft of the big aircraft. The general policy of manufacturing a competitive big aircraft in the world, of course, must follow Premier Wen’s instructions, concentrate on integrating the development and production resources of large aircraft, rely on national economic strength, scientific and technological innovation, rely on talents, and rely on the wisdom and creativity of every design and manufacturing personnel.

　　Safety factor, the first issue to be faced in large aircraft projects

　　Experts point out that the key to a large aircraft’s large fuel volume and long voyage is to consider safety factors, in addition to the following aspects:

　　At present, many airport facilities in Asia, Africa, Latin America and Oceania are very rudimentary, and the communication and navigation equipment is backward, or even there is no backup, which puts forward high requirements for the aircraft itself. Under special circumstances, the pilot must be prepared to land independently without relying on ground navigation, and the large aircraft to be manufactured in our country must have a clear understanding of this.

　　Second, it must be easy to operate. In view of the conditions of airports in Asia, Africa, Latin America and Oceania, large aircraft cannot pursue full electric operation, and must adhere to the combination of electromechanical and two sets of mechanical backup, and at the same time be easy to operate. Simply put, it is the optimization of Western avionics systems and Russian manual control systems. Therefore, such a large aircraft does not need Western avionics equipment as "foreign", nor can it be as "soil" as Russian manual control systems.

　　Third, the design of large aircraft should take into account harsh and extreme environments. The geographical environment of Asia, Africa, Latin America and Oceania is different, and the temperature difference between day and night in tropical desert areas is very large, which also puts forward high requirements for the fatigue strength, corrosion resistance and lightning protection of aircraft.

　　And four.Large aircraft should use the domestic Beidou navigation system.At present, although the GPS Global Position System is free, it is impossible to predict whether the situation will change in 2020. Therefore, even if it is not out of national pride of independent research and development, it should be adopted for economic and security reasons only. According to the conservative estimates of relevant people, by 2018, the Beidou navigation system technology will be very mature and has already been industrialized.

　　Improving the economy is an important foundation for participating in international competition

　　Industry experts believe that for the economy of large aircraft, in addition to engine fuel economy, the following aspects are also very important:

　　The first is that the self-weight cannot be too large. Due to the fact that the basic processes such as casting, forging and stamping in the Soviet Union are not up to standard, and the processing technology is not as good as those in the West, the main components of the aircraft cannot meet the design requirements, so they have to adopt reinforcement methods, resulting in problems such as low structural efficiency, high fuel consumption, and low transportation efficiency of the aircraft. Although the technology of European and American aircraft is good, it pays too much attention to economy, leaving little room for design indicators, so that users think that European and American aircraft are not as strong and solid as Soviet-style aircraft. Therefore, in addition to relying on advanced technology to reduce the inefficiency caused by the large weight of the aircraft, large aircraft in our country also need to use a large number of composite materials to reduce the weight Since the main markets for China’s large aircraft positioning are Asia, Africa, Latin America, and Oceania, as long as large aircraft are cheaper than European and American aircraft and more fuel-efficient than Russian aircraft, they will definitely find their own blue ocean.

　　The second is that it is easy to maintain and repair, and the maintenance and repair costs are cheap. The reason why Soviet aircraft are still widely used in third world countries is that they are easy to maintain and cheap. Therefore, large aircraft can take advantage of the advantages of Soviet Russian aircraft, otherwise they may lose the market if they are not high enough to be low enough.

　　The third is good versatility. There are many low-cost airlines in Asia, Africa, Latin America and Oceania, and most of them only purchase one type of aircraft or even one type of aircraft to reduce costs. Due to poor airport facilities, inconvenient transportation, and limited backup of aviation materials, this requires that the same model of large aircraft should be easy to disassemble and replace, and if necessary, the parts of one or two aircraft can be disassembled to ensure that one aircraft takes off.

　　Fourth, the continuity should be strong. China’s large aircraft must have its own characteristics, and the subsequent models must be inherited and continuous. Otherwise, the subsequent models of the aircraft cannot be accepted by airlines, because it is equivalent to two types of aircraft, and the maintenance cost will be greatly increased.

　　Reference News Network reported on April 4 that foreign media said that the famous Top 500 ranking shows which countries have the most powerful supercomputers in the world. The United States has kept its position as a powerful computer superpower, with China occupying the forefront, while Europeans without their own technical foundation can only be vassals of the United States.

　　According to the website of Austrian Anti-Party Magazine reported on March 30th, German Konrad Zuse invented the computer in 1937 — — Z1。 He later completed the Z3 in 1941, which was the first programmable computer in the world. The transistor was first invented and patented by Europeans.

　　People may think that the computer industry must be owned by Germany — — At least it is dominated by Europe. After all, the inventor was German — — Europeans. No, that’s not the case. In terms of computer hardware, Europe can be said to be unqualified.

　　According to the report, the performance of supercomputers is expressed in units of floating-point operation speed per second (TFlop/s). The most powerful supercomputer in Europe is Piz Daint of Switzerland, which ranks eighth, with a speed of 7788.9 tflops/s. This computer, which belongs to Swiss National Supercomputing Center, is produced by American Cray Company.

　　The United States is strong

　　According to the report, American computers frequently appear in the top 100, occupying the 3rd, 7th, 12th, 15th, 16th, 19th-21st and many other positions. Since the x86 division of IBM responsible for supercomputers was sold to Lenovo in China in 2014, the current ranking of IBM computers (4th, 6th, 14th, 54th and 68th) is shared by China and the United States.

　　The United States occupies 31 places in the top 100. Because the rankings of other countries that use American processors are not counted, this figure does not reflect the real strength of the American computer industry (specifically, the chip giant Intel).

　　According to reports, most supercomputers in Japan use Fujitsu processors. So is Japan very independent? Not exactly. Fujitsu is an R&D and production partner of Intel. Therefore, Intel’s genes also promoted the development of Fujitsu processors.

　　According to the report, Europeans have no ability to succeed on their own in supercomputer technology. The most powerful supercomputer in Europe must be purchased — — Buy from America. Apart from Switzerland, Finland, Sweden, Britain and Germany are all customers of Cray. American computer companies do well in Europe. HP’s customers include Poland, France and Czech Republic.

　　According to the report, there are also many computers in China in Europe. Lenovo and Huawei are famous Chinese brands in Europe. Italy and Germany are Lenovo’s customers. Lenovo has bought part of IBM’s computer business little by little in recent years. Therefore, in the past, the customers of "Blue Giant" became Lenovo’s customers. With the help of China — In the framework of cooperation between Central and Eastern Europe, Poland has become a close partner of China people, especially in the computer field. Poland’s supercomputers occupy the 48th, 90th and 92nd places in the top 100. The computer ranked 48th was purchased from Hewlett-Packard in the United States, but now it attaches great importance to cooperation with the United States and China.

　　China processor is far ahead.

　　The report said that in terms of supercomputers, China has not caught up with the United States — — But surpassed the United States. China occupies the 1st, 2nd, 42nd, 67th, 74th, 77th, 78th, 86th, 91st and 96th positions in the top 100 respectively. Tianhe-2, ranked second, still uses Xeon processors from the United States. Now this is a thing of the past.

　　During this period, China people developed their own processors — — The Shenwei processor makes Intel’s Xeon look old. Top 500 ranked first in China Shenwei Taihu Lake Light, and its peak speed reached 125,435.9 tflops/s. The third-ranked American Cray Company’s supercomputer using AMD Opteron processor has a peak speed of "only" 27,112.5 tflops/s. This is roughly only 22% of the light of Taihu Lake in China.

　　According to the report, the best supercomputer in the European Union is the Mistal in Hamburg (using American processors), which ranks 33rd, with a speed of 3,147.8 tflops/s, only 2.5% of the light of Taihu Lake. The most powerful computers in the European Union can only achieve 2.5% of the performance of China supercomputers by using American components.

　　Now can you understand why Trump wants to make America great again? He is right to say so. In the field of computers, the technology of the United States is many light years ahead of that of Europe, but it is only ahead of Europeans, not China.

　　Specifically, a giant battle, a battle between the United States and China, and a processor war between American chip giants AMD and Intel and Shenwei of China Jiangnan Computing Technology Research Institute have begun.

　　According to the report, with the launch of processors such as Huawei Kunlun and FusionServer, another China company is also shaking the position of AMD and Intel. It should not be forgotten that Huawei and Intel have a technical cooperation relationship. With Intel’s genes, Huawei is now preparing to step out of Intel’s shadow and bathe in the sunshine of the computer industry independently.

　　Europe’s achievements in the computer field are few and far between. Think about it, only such achievements can be achieved with American processors. In the field of computers, European technology is virtually the same as non-existence. This is a shame for Germany and Europe: they waste the advantages and great legacy created by people like Chuze.

"Listen to the Wind" was created by many masters.

Siu Fai Mak and Zhuang Wenqiang.

Tony Leung Chiu Wai denied that the film was a copy of Lust, Caution when he played the old corner of Wang Baoqiang.

　 　 Listening to the Wind is adapted from Mai Jia’s classic spy novel, which tells the story that agent Zhou Xun finds Tony Leung Chiu Wai, a street blind gangster, and with the help of Tony Leung Chiu Wai’s superior hearing, finds the enemy radio station that has disappeared for many years and obtains military information to defend the country. Zhuang Wenqiang said, "There are many spy wars in The Listener, but some adaptations will be made to the original."

　 　 In fact, Mai Jia’s work has long been made into a TV series "Assassination", which was a smash hit, and the role played by Tony Leung Chiu Wai was played by Wang Baoqiang in that year. Referring to the difference in temperament between them, Zhuang Wenqiang said with a smile, "In fact, when I first read this book, I thought that this role should be played by Xiaogang Feng, but it is impossible. Of course, it is impossible for Tony Leung Chiu Wai to play Xiaogang Feng or Wang Baoqiang."

　 　 On the same day, The Listener also exposed the trailer for the first time. Many scenes and characters in it will make people think of The Wind and Lust, Caution, but Siu Fai Mak doesn’t think so. "Some people say it is like it. In fact, you will know that it is not like it after watching the whole film, and it is different from our previous shooting style."

Next page:Zhou Xun turned into an emotional liar. Tony Leung Chiu Wai gave up the electric eye and played the blind PK Andy Lau.

　　　　"Writers are entertaining, scholars are entertaining, and now even the mayor is entertaining." Yesterday (6th), a video of Zhao Xiaoming, the mayor of Zhangjiajie, showing people with exaggerated cartoon image spread on the Internet, which caused a thousand waves, causing widespread controversy among netizens at home and abroad.

　　"Cartoon mayor" triggered online controversy

　　　　The opening of "2009 Zhangjiajie International Country Music Festival in China" is just around the corner, and Mayor Zhao Xiaoming can be described as a pioneer. As the "image ambassador" of this music festival, Zhao Xiaoming did not hesitate to "vilify himself" and showed people with the cartoon image of "grinning" in the image propaganda film of the music festival. The mayor personally endorsed a large-scale music festival and "sacrificed his life to get an electric shock" to appear on the screen with his exaggerated cartoon image, which may be the first time in China.

　　Netizens called him "the most handsome mayor in history"

　　　　Mayor Zhao’s "self-destructive image" and "giving his life to get an electric shock" caused a strong controversy on the Internet. A netizen in Hainan commented that "what does this make the mayor’s authority and dignity?" This netizen’s statement was immediately refuted by other netizens. Most netizens believe that the mayor is a "public servant" and does not have to be "high above" to reflect the authority of officials. Mayor Zhao’s act of being close to the people makes people feel very cordial; A netizen in Shandong said that "the creativity is very good, but the painting is too rough", which means that the exaggerated cartoon image of Mayor Zhao is "not flattering", while a netizen in Guangxi said that "the sexiest organ of a man is his mind, so he should be given a’ most handsome mayor in history’!"

　　With some comments from netizens:

　　　　Beijing netizen: like one! Such a move can increase the intimacy of officials!

　　　　Jiangsu netizen: I hope all officials can be closer to the people in reality!

　　　　Shanghai netizen: What’s the fuss? Foreign presidents personally design their own cartoon images!

　　　　Shandong netizen: Creativity is good, but can’t it be painted better? ? This is not difficult, is it? ?

　　　　Guangdong netizen: mayors all over the country should learn from this man. Don’t put on an official airs all day!

　　　　Hunan netizen: Zhangjiajie has made great progress in urban construction and city appearance in the past two years. As a native of Zhangjiajie, I sincerely thank Mayor Zhao.

　　　　American netizen: This is a kind of progress and closeness to the people. Officials in China often look arrogant. Do more similar things, which is beneficial!

　　　　Shanxi netizen: very good, emancipate the mind and set an example of innovation! More approachable image.

　　　　Fujian netizen: It is more important than cartoons to manage Zhangjiajie’s tourism environment better!

　　　　Zhejiang netizen: it’s quite good, but it’s a little rough!

　　　　Netizen in Chongqing: I hope more officials can be as popular as Mayor Zhao.

　　　　Korean netizen: Look at those objections, and China’s official standard thought can be seen.

　　　　Sichuan netizen: Hunan is the central region, but the dancer on the right in this picture is dressed like a western ethnic girl, not a local Miao and Tujia costume, which is a failure.

　　　　Netizen in Liaoning: Very good, approachable and innovative. Most people should like it.

　　　　Macau netizen: Controversy is also beneficial, at least raising the popularity of the music festival.

　　　　Netizen in Xinjiang: The mayor is so handsome. I like him, and the music is very nice, which gives people a shocking feeling.

　　　　Shaanxi netizen: My wife clamored to go to Zhangjiajie several years ago, but she never made it. This time, you can see that tickets for many performances have not increased in price, so let’s go together on annual leave!

　　　　Jiangxi Netizen: Since it is the China International Country Music Festival, why should we use American country music songs? Why not use China folk music? Are you holding a music festival in China or an American country music festival in China? How dare you say that? While all over the world are building up the confidence of local culture, the mayor of China still uses American music as a propaganda sign of China folk music. Is this a manifestation of its contemporary "national inferiority complex"? Why do music festivals in China promote American music?

　　　　Hunan netizen: this is the perfect combination of advanced management concept and Zhangjiajie’s original natural scenery. I believe that music energy saving can be as successful as promotional film, and we look forward to it!

　　　　Netizen in Hebei: Hunan people just dare to think, dare to be the first, and live up to the eternal famous couplet at the entrance of Yuelu Academy.

　　　　Guangxi netizen: I don’t think the cartoon image of Mayor Zhao is ugly at all. On the contrary, I can give him a "most handsome mayor in history" or something. The most handsome, coolest and sexiest organ of a man is not eyebrows, eyes, nose, face, muscles, but-thoughts! (Reporter Wang Xiaoyang)

A few days ago, the film "Hot Search" appeared at the Golden Rooster Film Festival and held a screening event. Director Xin Yukun, producer Wang Hongwei, starring Zhou Dongyu, Song Yang and Justin attended the post-screening interaction to share the behind-the-scenes story of film creation with the audience. In this film festival, Hot Search won the 36th China Golden Rooster Award, and the domestic new film exhibition was the most anticipated feature film by the audience.

The film "Hot Search" tells the story that Chen Miao (Zhou Dongyu), the editor-in-chief of the media, penetrated the traffic password, created an explosive article and rushed to the hot search, but indirectly boosted the female student of the bully to jump off the building. At this time, Chen Miao accidentally discovered the help information sent by a female student and involved a sexual assault case. Chen Miao’s partner He Yan (Song Yang) and investor Peng Yue (Justin) are involved in it. Public opinion has turned many times, what kind of interest chain is hidden behind the incident, and a public opinion war for the weak has started … The film will be officially released on December 1.

Xin Yukun, the director of Heart Labyrinth and Silent Burst, didn’t choose to make a fuss about suspense structure this time, but focused on the network theme closely related to the present, and explored the complex humanity behind the "network public opinion war". Xin Yukun said that in such a story, the suspense skills full of design will weaken the sense of reality. "I am willing to sacrifice suspense and impress the audience with authenticity.".

At the scene, producer Wang Hongwei said that movies have the responsibility to show social phenomena. Xin Yukun also said, "What happened in the network in recent years is the power of awakening, and it is necessary to be recorded and transmitted.". "The film can’t tell all the complicated causes behind the network, but I hope it can help you sort out the whole story and improve your ability to identify the truth."

This time, Zhou Dongyu plays Chen Miao, the editor-in-chief of the media. At the scene, Zhou Dongyu also shared his love for the role. "Chen Miao believes that one thing will die to the end, and this tenacity in her body particularly attracts me.".

Song Yang plays He Yan as a "middle-aged social animal" trapped by interests. Song Yang said frankly that the middle-aged crisis dominated the choice of what to say, and the reality and pressure made him constantly compromise, and he was powerless to the truth. Yuan Hong played a "perverted and bad" villain. Peng Yue held power and did whatever he wanted. Justin couldn’t help but say "I want to beat him!"

　　On March 15th, 2016, Google’s artificial intelligence "AlphaGo" defeated Go world champion Li Shishi with a disparity score of 4-1. On May 27th, 2017, China’s Ke Jie, who is recognized as the world’s No.1 Weiqi player, lost 0-3 in a three-piece chess contest with Afa Dog.

　　It is reported that in the research team of "Afa Dog", only Huang Shijie can play Go for four amateur paragraphs. The level of amateur four-stage Go may only be to understand the basic rules and some simple skills of Go. And once he is combined with the artificial intelligence "Alpha Dog", he can actually play a super-class chess player without winning. This fact reminds us that a commander who understands basic operational rules and tactical principles, if combined with the corresponding operational command-aided decision-making artificial intelligence, will defeat the first-class military commander without artificial intelligence?

　　Where does artificial intelligence come from?

　　Electronic computers and the Internet are born in response to military needs, and so is artificial intelligence, a branch of computer science. In 1939, World War II broke out and Britain declared war on Germany. Alan mathison turing, a mathematician and logician engaged in research work in Cambridge, enlisted in the army and joined the code-breaking station ordered by Churchill. The deciphering machine named "Turing Bombe" developed by them successfully cracked the communication code of the German Supreme Command Center, code-named "Enigma". Later generations commented that the "Turing Bomb" advanced the end of World War II by at least two years. After the war, Turing mainly engaged in the pioneering research of computer programming theory, neural network and artificial intelligence. He was called "the father of artificial intelligence" because of a series of outstanding achievements.

　　According to the Chinese definition, "intelligence" includes people’s "wisdom" and "ability", that is, intelligence and ability. The English expression of artificial intelligence is: artificial intelligence; Artificial means "artificial" and "imitation", which is strictly translated. Only Artificial Intelligence can be translated into "artificial intelligence" or "artificial intelligence". In fact, the current "Alpha Dog" is really just a "Go Brain", which decides how to play chess, and the chess movement is done manually.

　　The superb Go level of "Alpha Dog" benefits from the deep learning method provided by new technology with big data science and technology as the core. It can be described visually as follows: the program only describes the learning and thinking methods of "Alpha Dog", and the improvement of its intelligence level depends on the accumulated data. For "Alpha Dog", the data include the chess score of Go masters, the chess score of real opponents and the chess score of "Alpha Dog" playing by itself. These chess scores are the source of "intelligence" for "Alpha Dog" to improve its chess skills. In terms of digesting the chess score and learning progress, the ability of "Alpha Dog" is beyond anyone’s reach. Ke Jie, the world champion, can play up to 1,000 chess games a year, while Alpha Dog can play 1 million chess games a day.

　　This makes the improvement of "Alpha Dog" chess power open, and there is almost no "ceiling". On the premise of not modifying the "Alpha Dog" program, the "Alpha Dog" can achieve the progress and improvement of "new day by day" or even "new from time to time" as long as the chess score of high-quality chess is continuously increased. It is objectively proved that the research team of "Alpha Dog" has basically mastered the winning mechanism of Go and described it in programming language.

　　This remarkable ability includes two aspects: one is to judge the advantages and disadvantages of the existing disk; Second, based on this judgment, the possible position of the next move is decided, and a decision is made after the value judgment of several possibilities. Whether it is to judge the value of a certain move or the quality of the whole disk, it is necessary to construct a certain mathematical model and accurate algorithm.

　　The success of "Alpha Dog" shows that its R&D team’s efforts in this regard are very close to human cognition, and machine learning has stood on the threshold of human brain learning. Super-first-class chess players found that "Alpha Dog" can even discover the laws and knowledge that human beings have not discovered for thousands of years from big data, which means that human beings have opened up new channels for expanding their knowledge system.

　　What is the use of artificial intelligence

　　Because of the realistic ability and potential ability displayed by artificial intelligence, all countries in the world are trying to use artificial intelligence for national defense and army building. As far as reality is concerned, the application of artificial intelligence in military field is mainly reflected in three aspects.

　　The first is an unmanned combat platform. The existing unmanned combat platforms, whether unmanned aerial vehicles, robots on land or unmanned submarines at sea, have low intelligence. Generally, it only replaces people for some specialized operation. On the battlefield in Iraq, the US military used more than 4,000 robots to detect mines, roadside bombs and operate in some dangerous areas. The US military has more than 8,000 aerial unmanned systems and more than 12,000 ground unmanned systems, which have become an indispensable part of the US military’s operations. The development of artificial intelligence technology can make unmanned platforms more "smart" and improve the combat effectiveness of weapons and equipment, but it is not possible for unmanned platforms to make independent decisions so far.

　　The second is intelligent precision ammunition. The US military used advanced laser or TV guidance in missile technology, which began in the Vietnam War in the 1970s. Its "Gemstone Road" missile hit more than 60% on the battlefield in Vietnam. The JDAM "Joint Direct Attack Ammunition" equipped by the US military adopts a more advanced guidance mode: inertial guidance +GPS satellite guidance. The "Joint Direct Attack Ammunition" during the Gulf War can only add target data before taking off. In the Iraq war, its receiver can receive the target data from navigation satellites, and can change the target at any time to destroy it, and its "intelligence" is obviously improved.

　　The third is command-assisted decision-making. Think of "Alpha Dog" as a command and decision system of black-and-white confrontation, and its excellent performance in cognitive decision-making of black-and-white confrontation, and its ideas and methods should be used for reference for operational command and decision-making.

　　Situation awareness on the battlefield is very complex, and multi-source intelligence gathers to form massive data, which cannot be completed by relying on the commander’s manual analysis. Artificial intelligence has great advantages over human beings in searching, storing, calculating and mining massive data. Introducing a deep learning algorithm similar to "Alpha Dog" to intelligently analyze satellite images and radar data will greatly improve the efficiency of intelligence analysis.

　　In addition, at present, the cognitive understanding of the comprehensive battlefield situation depends largely on the commander’s experience and intuition. Using the "value" algorithm similar to "Alpha Dog" to judge the situation of Go and the probability of winning or losing, and learning from the "strategy" algorithm similar to "Alpha Dog" to determine the position of the player, it can provide auxiliary support for the commander’s operational decision.

　　However, the application of artificial intelligence in the military field is far from reaching the level of independent decision-making like "Alpha Dog" Go. In November 2001, Predator UAV launched an attack on Al Qaeda military commander Mohammed Latif in Afghanistan, which became the first anti-terrorism actual combat of UAV. But it is the drone operator who controls from the rear who presses the "fire" command. Even so, it will inevitably bring collateral damage to innocent civilians. In 2013, Pakistani officials announced that since 2008, the US military has launched more than 300 drone air strikes in Pakistan, killing more than 2,000 innocent civilians.

　　What is the future of artificial intelligence?

　　From the situation that the world’s first-class Go players, Li Shishi and Ke Jie, have little chance to win the game against "Afa Dog" and the result of complete defeat, it is not exaggerated to draw the conclusion that artificial intelligence has surpassed human beings in the field of Go. In the game of Go, the obvious advantages of artificial intelligence are as follows: without fatigue curve, intelligence will not decay with time; There are basically no mistakes, and no opportunities will be given to opponents where they can; Free from emotional interference, not angry and impulsive because of the provocation of opponents; Learned and memorized, learning and playing chess more than ten million times before the game, which is beyond the reach of human beings; Powerful computing power is beyond the reach of human beings.

　　But the victory of "Alpha Dog" is, in the final analysis, a human victory. The research on the mystery of human thinking and brain science is still superficial, and the development of human brain is far from exhausted, but the mechanism and composition of computers and artificial intelligence, no matter how powerful, are well known, because they were originally designed, manufactured and developed by people.

　　At least so far, any artificial intelligence has the ability given by human beings. It is not surprising that it surpasses human beings in some ways. Humans make up for their own shortcomings by making various tools, a process that began in the Stone Age. Today, the major means of transportation far exceed human’s walking ability, and various machine manufacturing systems far exceed human’s unarmed manufacturing ability. Digitalization, networking and intelligence are the basic tracks of the development of the information society. It is expected that artificial intelligence will show its great power in the mature stage of the information society.

　　Then, will there be a first-class military commander completely defeated by an artificial intelligence command system with strong deep learning ability in the battlefield in the future? To fully answer this question requires a masterpiece, but there are many essential differences between chess game and battlefield confrontation. For the following reasons, the author thinks the answer is no.

　　One is the one-way transparency of the battlefield and the two-way transparency of the chess game. In the game of Go, both sides of the game are equal and transparent, regardless of the chessboard structure or the disk situation. However, the modern battlefield spans the virtual and physical space of land, sea, air, sky, electricity and internet, and the weather, weather, rain and shine, flood and tide are unpredictable. Clausewitz’s "battlefield fog" covers the battlefield. Even if it is a close confrontation, the battlefield space can never be transparent in both directions. The party with strong perspective observation can realize that the battlefield is more transparent to itself. Two-way reciprocal transparency in battlefield space has never existed and will never exist.

　　The second is the certainty of the value of chess and the uncertainty of the effect of combat action. In the game of Go, the value of one player’s move is almost certain on the disk. An opponent can weaken the value of his next move, but he also has the same chance to fight back.

　　However, the effect of combat operations on the battlefield is uncertain. In October 2001, the United States Joint Forces Command published "Effect-based Operations", and the US military formally accepted the theory of "Effect-based Operations". In 2008, General james mathis, the current U.S. Secretary of Defense and then commander of the United States Joint Forces Command, issued the Guide to Effect-based Operations, which officially abolished the theory of Effect-based Operations. Matisse’s reason is: "All combat environments are full of countless changing factors, so it is logically impossible to accurately predict the outcome of an action."

　　The third is the authenticity and deception of the situation. On the board of Go, the situation of the board seen by both players is clear and true. But as Lenin said: "There is no war in the world without strategy." Strategic and tactical deception is a common tactic in war.

　　The fourth is the strict game between the two sides and the potential multi-party participation. On the chess board, the two sides of the game are strictly limited between the two sides. Although there is a team behind the "Alpha Dog", it cannot change the nature that they are one of the two sides. In the history of human wars, especially since World War II, many local wars are actually "proxy war", where two sides or three parties join in the battle. Behind them, the situation is complicated and the behind-the-scenes promoters are hidden. For example, in the battlefield in Afghanistan, al-Qaeda is the target of the US military; On the Syrian battlefield, however, they may get some support from the US military because they are anti-Syrian forces.

　　The fifth is the symmetry and asymmetry of space, time and weapons and equipment. In the game of Go, the time and space of both sides are symmetrical, and the weapons and equipment are black and white chess pieces. Although they are black first, they must pay back. In the real battlefield, preemptive strike is asymmetric in time, and air-to-ground attack is asymmetric in space. The wars of the United States against Iraq and Afghanistan are the wars of information-based weapons and equipment against mechanized weapons and equipment in the agricultural era, respectively, and there is intergenerational asymmetry in weapons and equipment between the opposing sides.

　　Sixth, the certainty of chess rules and the flexibility of operational principles. In the game of Go, "Jinjiao’s silver-edged grass belly" is the basic value judgment criterion, and it is the basic chess rule … … The connection is broken, the dragon is encircled, and the eye position is broken, which is to avoid passivity with all one’s strength. These rules are basically certain and must be observed. Militarily, victory is no longer an important tactical principle. However, in the Anti-Japanese War, Liu Bocheng made a second ambush in Qigen Village, which became a classic of military command and a stroke of genius.

　　Clausewitz said: War is a kingdom of uncertainty. The most essential difference between Go and military confrontation is the difference between certainty and uncertainty. The success of artificial intelligence is an amazing scientific achievement; But military command is not only science, but also art. The superb command art is more derived from the commander’s imagination and inspiration, generate, who said, "The wonderful operation is single-minded".

　　Generally speaking, the application of artificial intelligence in the military field will enter an unprecedented active era with the development of technology, but the leader of war or battlefield will always be people.
