  Fukuhara Ai


    Men’s singles three tigers will advance to eight generals


    According to Xinhua News Agency, Beijing, 21st, in the men’s singles table tennis competition of the Beijing Olympic Games, with the typical "China speed" and "three tigers in table tennis", they easily beat their opponents and advanced to the quarterfinals.


    Before the game, China’s main rivals, South Korean star Ryu Seung-min, German "golden boy" Bohr and Belarusian samsonov, were eliminated by other opponents, and they missed the opportunity to compete with China players.


    Wang Liqin, the former king, eliminated Shi Lage, a famous European player, 4-0. Earlier, Wang Hao eliminated Han Yang of Japanese team 4-1. Ma Lin, who started at the same time as Wang Liqin, also beat Greek glinka by the same score at another table.


    Three China players advanced to the quarter-finals, reflecting the amazing "China speed": Wang Hao took 29 minutes, Wang Liqin took 25 minutes and Ma Lin took 26 minutes.


    The first two rounds were bye-bye. As the seed player, the "Three Tigers of Guoping" didn’t show up until the third round. On the same day, she played two sets in a row, first reaching the top 16 at noon and then entering the top 8 at night.


    On the next match day, Wang Hao will meet Gao Lize, Wang Liqin will fight Tan Ruiwu and Ma Lin will fight Sang Eun Oh. Only two European players, Croatian primorac and Swedish persson, will also compete in the semi-finals. The prospect of China’s men’s singles gold medal is becoming clearer.


    Women’s singles three will break into the semi-finals


    China’s Zhang Yining, Guo Yue and Wang Nan all made it to the semi-finals of women’s table tennis singles at the Beijing Olympic Games on the evening of 21st.


    Last night, the women’s singles quarter-finals started. Zhang Yining first played against Feng Tianwei of the Singaporean team, fighting for four sets, and Zhang Yining beat her opponent 4-1.


    Wang Nan met Tieyana of Hongkong team in China in the quarter-finals. The two sides have played against each other many times in history and know each other well. However, Tieyana was in a very poor state yesterday. She lost the first two games with a disparity score of 5: 11 and 4: 11. Although she pulled back one game with 13: 11 in the third game, the fourth and fifth games reappeared in a depressed state, losing two games with 2: 11 and 4: 11. In this way, Wang Nan defeated his opponent by a total score of 4: 1 and entered the semi-finals.


    Young Guo Yue’s opponent in the quarterfinals is Wu Xue of Dominica. There was no suspense in the game, and Guo Yue easily won 4-0 in straight sets.


    In the other quarter-final, Li Jiawei of Singapore defeated Wang Chen of the United States, becoming the only non-China player in the women’s singles semi-finals.


    Shi Zhihao, head coach of China women’s table tennis team, believes that all three players of China team have played their normal level so far, and China team will continue to strive for winning the women’s singles gold medal tomorrow.


    The semifinals and finals of women’s table tennis singles will be held on the 22nd. The two semifinals will be played against Zhang Yining against Li Jiawei and Guo Yue against Wang Nan. (Meng Xin)


    Fukuhara Ai smiled and left.


    Xinhua News Agency, Beijing, August 21st-Japanese player Fukuhara Ai used to cry when she lost, but after losing to China’s Zhang Yining in the women’s singles eighth final of the Beijing Olympic Games on August 21st, Fukuhara Ai left the field with a smile.


    "I’m quite satisfied with my performance in this competition, and I’m also very satisfied with my performance in the whole Beijing Olympic Games. If I get out of 100 points, I can get 90 points," Fukuhara Ai said.


    After the match with Zhang Yining on the 21st, Fukuhara Ai’s journey to the Beijing Olympic Games stopped: "I am in a good state of mind, and it is an honor to play against a world champion like Zhang Yining at the Olympic Games." On the 20th, Fukuhara Ai also told reporters that Zhang Yining might not play well due to the pressure at home. On the 21st, Fukuhara Ai told reporters, "I miscalculated yesterday, and Zhang Yining was not nervous at all in today’s game, and played very well."


    However, Fukuhara Ai also has regrets in this Olympic Games, that is, she failed to win a medal. She said: "It is a pity that the Japanese team failed to win a medal in both the team and the singles, but we have brought everything we usually train into full play, and there is nothing to regret if we tried our best."


    Put on a spare racket.


    Zhang Yining’s heart is half cold.


    "When the referee asked me to play with a spare racket, my heart went cold at once." Zhang Yining said after the game on the evening of 21st.


    According to Zhang Yining, when the match with Singaporean player Feng Tianwei was about to start, the referee suddenly informed her that her racket was unqualified and asked her to play with a spare racket. "I don’t know what’s wrong with my racket now, maybe it’s because the glue is too thick. The sponge on the spare racket is still three years ago, and the quality is much worse. I’m a little lacking in confidence before the game starts. "


    Before the game, Zhang Yining was generally thought to beat Feng Tianwei easily, but the game was full of tension. Zhang Yining struggled to win the first game with 13: 11, and lost the second game with 12: 14. Zhang Yining won the next three games, but the scores were very close, with 14: 12, 12: 10 and 13: 11 respectively.


    "After changing the spare racket, the temperature and radian of the power are somewhat different from those of the normal racket, and it is very awkward to fight. It’s not easy to beat your opponent. " Zhang Yining said.


    After the game, the referee took away Zhang Yining’s spare racket, and it is said that it will be tested again. Zhang Yining reluctantly told reporters that she had temporarily lost a racket. According to Xinhua News Agency


    Jiao Zhimin:


    National ball dominance does not depend on sea tactics.


    China table tennis team is getting closer and closer to achieving the goal of "Grand Slam" in this Olympic Games. Jiao Zhimin, a famous former China table tennis player and world champion, who now lives in South Korea, wrote an article revealing the secret.


    Jiao Zhimin revealed: "The founder of’ straight double-sided play’ is Liu Guoliang, the coach of China table tennis national team. He is a typical backhand player. Liu Guoliang realized that it was hard to hit the backhand straight, so he tried to stick rubber on the back of the racket to hit the ball. I didn’t expect this to become an opportunity for China table tennis to make a milestone development. Then Marin and Wang Hao became familiar with this style of play. Among them, Wang Hao can master the double-faced play more skillfully, making it reach the peak. "


    In the eyes of most people, China table tennis dominates the world, relying only on a huge basic training system and a steady stream of talents. However, as a world champion who used to be the standard-bearer of table tennis in China, Jiao Zhimin has a different view. "China table tennis coaches are always faced with the problem of how to dominate the world. They have been racking their brains to study new technologies. As a result, there are even players who play table tennis alternately with their left and right hands in China, who can hit the ball forehand in any direction, although this technology is not mature enough to appear on the international stage. "


    "Foreigners think that table tennis in China relies on the sea of people tactics because they don’t see the efforts made by coach China to develop new technologies." Jiao Zhimin said.

The wall fell and everyone pushed! Buden holzer was bombarded by his former disciples, and he lacked more than just coaching adaptability.

Recently, Ibaka, a former Bucks insider, accepted an exclusive interview with Chalana, a famous player of The Athletic. In the interview, he bombarded Buden holzer, a former Bucks coach, and questioned Buden holzer’s communication ability. It seems that Buden holzer’s dismissal is not only due to the lack of adaptability in coaching, but also due to the lack of communication skills.

Ibaka said that when he signed with Bucks, he knew that his playing time would not meet his expectations, and he had communicated with Buden holzer about playing time. Ibaka revealed: "At the beginning, Buden holzer said in front of me,’ Listen, I can’t promise you anything if you come to the Bucks. However, you never know what will happen. The season is long and players will be injured. You must always be prepared. " "

Ibaka can understand that Buden holzer has his own habits of employing people. After all, the Bucks have big Lopez and Portis inside. What Ibaka couldn’t understand was that when a player was injured, he still didn’t get playing time. When the wounded returned, he got playing time instead.

Ibaka believes that the lack of communication is the main problem. "When I communicated with the management, they told me differently. They appreciated me and wanted me to stay in the team. When I returned to the stadium, everything was different again, and things developed to the point where I couldn’t stand it. I love this sport, but if these things take away my inner peace and fun, it is not worth it. I won respect in the league. You have to communicate at least. I didn’t ask to play. What I want is communication. "

I can hear that Ibaka is full of complaints about Buden holzer. He also compares with Clippers coach Tyrone Lu. He said, "I played for Clippers, and I have great respect for Lu’s guidance. He will call me in the morning and say,’ I will let young players play more this week.’ My answer is yes, no problem. Whether you like the coach’s decision or not, I just have to keep my career in the end. At least I know I have to keep working hard for the next two weeks, and then when things change, he will call me and say,’ Listen, I’ll let you go tonight and get ready.’ Even if he’s not sure whether to let me go, he’ll tell me, that’s all. "

Ibaka played 16 games for the Bucks last season, averaging 11.6 minutes, scoring 4.1 points and 2.8 rebounds. Before the trading deadline, Ibaka was sent to the Pacers and was subsequently laid off. At present, the 33-year-old Ibaka is still a free agent. He said that he can still contribute to a team and he can bring experience.

Manchester City has won the Premier League three times in a row, only two finals away from the triple crown, and the best team in history is about to be born.

With Arsenal losing 1-0 to Nottingham Forest, Manchester City locked in the Premier League title three rounds ahead of schedule. Manchester City has won the Premier League three times in a row. In the past six years, it has only fallen behind the champion once and won the Premier League five times. Manchester city can be said to be one of the most successful teams in football today, and one of them can even be removed.

?

Behind the success of Manchester City, we have to mention their coach Guardiola. Since Guardiola took over Manchester City in 2016, he has made a major transformation of the team. He rebuilt the team and led them to get the best Premier League results in history in an unprecedented way, with more than 100 points in a single season and the highest number of goals in a single season. Guardiola extended his success from Barcelona to Bayern Munich and reached another peak in Manchester City.

?

Guardiola’s success mainly lies in his mastery of football tactics and strategies. He can always adapt to the game and make the players play their best in the most effective way. In other words, he is a very good tactician. His lineup rotation strategy is also excellent. In some important games, he will choose to send different starting lineups, which leads to the opponent’s inability to cope. At the same time, he is also a very good psychologist. Guardiola can give players confidence and strength, and inspire their fighting spirit and greatest potential. This is very important for the success of Manchester City.

?

In addition, the success of Manchester City is also attributed to every player in the team. From Harland to De Braune, from Gundogan to Aker and Akanji, everyone in the Manchester City squad has made important contributions to the team. Their efforts and talents are a major factor in Manchester City’s reversal of Arsenal’s winning the Premier League title this season. Whether you are a loyal supporter of Manchester City or an amateur of football, you can’t deny that there is a real team spirit behind Manchester City’s success. As a player and opponent of Manchester City, everyone knows that this team is built on extraordinary skills and excellent management. More importantly, they have a firm determination, which is a necessary condition for winning the competition.

?

Not only winning the game, Manchester City is also spreading the beauty of football to the whole world. Their players and coaches have become one of the most important benchmarks in football, and at the same time, they are also helping the sport become a more popular cultural phenomenon. Finally, just like football is a team sport, the success of Manchester City is the result of teamwork. This team has demonstrated persistent and consistent efforts and dedication, as well as a true love for football and team spirit. This is a historic achievement that deserves the respect and reverence of all football fans and players all over the world.

Now Manchester City has successfully won the Premier League title, only two finals away from the treble. The FA Cup final will face Manchester United, the same city rival, and the Champions League final will face Inter Milan. Manchester City aims to win the treble! We will wait and see!

Reversed by 3-1, super cold! Bayern set a shameful record in the history of the team and forced the suspense of the Bundesliga title.

At 0:30 on May 21st, Beijing time, in the 33rd round of Bundesliga, Gnabry failed to save the goal, and Bayern was reversed by Leipzig 3-1 at home.

This is the first time Bayern lost to Leipzig at home, and it also ended the unbeaten record of 11 games against Leipzig in various competitions.

After losing this crucial game, Bayern was only one point ahead of Dortmund in the case of one more game, and it is very likely that it will miss the Bundesliga’s 11 consecutive championships. After getting the key 3 points from Bayern, Leipzig has opened a gap of 4 points with Freiburg, the fifth in the league, with only one round left, and locked a seat in the Champions League ahead of schedule.

Game review-

In the 33rd minute, Szoboszlai volleyed in the middle of the restricted area and was saved by Sommer.

In the 39th minute, Cancelo made a cross from the left, and Koeman headed the ball from close range and missed the right post.

In the 41st minute, after Szoboszlai buckled the defender, his left foot shot slightly higher than the crossbar.

In the 64th minute, Leipzig made a quick counter-attack. After Nkunku’s right cross in the restricted area was blocked, Lemmo Middle Road followed up and pushed the goal, and Leipzig equalized the score 1-1.

In the 74th minute, pawar was awarded a penalty for kicking Nkunku. Nkunku personally took the penalty and Leipzig overtook the score 2-1.

In the 84th minute, hand ball in Mazravi’s penalty area was awarded a penalty again, and Szoboszlai scored a penalty kick, and Leipzig extended the score to 3-1.

Since then, neither side can rewrite the score again, and finally Bayern lost to Leipzig 1-3 at home.

Leeds United manager picked up a 5-pound note and handed it to the fourth official. After being rejected, he put it in his pocket for heated discussion.

In the 37th round of Premier League, West Ham played against Leeds United at home. In this crucial battle of relegation, there was an interesting scene: Leeds United coach Al Daisy  found a note worth 5 pounds on the sidelines, and he did not hesitate to give it to the fourth official beside him with a smile. Unfortunately, the other party refused to accept this gift. Seeing this scene, Al Daisy  was still smiling, and like a wild crane, he put the 5-pound note into his pocket. This move seems to be a reappearance of the old tradition, which makes people laugh.

In the 37th round of the Premier League, Leeds United team was challenged by two powerful teams, West Ham and Tottenham, which means a life-and-death relegation battle for Leeds United. Victory or failure will have a far-reaching impact on the team’s fate. It is at this critical moment that Leeds United coach Al Daisy  has become a key figure with high hopes from fans. His rich coaching experience and deep understanding of the Premier League have given the team more opportunities and advantages in this life-and-death battle. As a seasoned football coach, Al-Daisy  plays a particularly important role in the team. He plays a leader who guides and leads the team forward. Through his accurate analysis of the game and tactical deployment, Leeds United will give full play to its own strength and proud team spirit in this key battle, and inject a shot in the arm for the team’s relegation road.

In the 37th round of the Premier League, Leeds United faced double challenges from West Ham and Tottenham. For Leeds United, this means that they must seize every opportunity to score goals and strive to stay ahead in the life-and-death relegation battle. In the 17th minute, Leeds United finally got their chance. Mckenney’s foul ball went into the penalty area, and Rodrigo seized the opportunity to blast his opponent’s goal with a volley, winning an important goal for Leeds United, giving them a 1-0 lead. This goal not only shows Rodrigo’s excellent shooting, but also highlights the team’s spirit of cooperation and tactical cooperation, which makes Leeds United fans feel relieved and injects a booster into the team’s relegation road.

Al-Daisy  paced back and forth on the sidelines, and suddenly he found a golden piece of paper shining near the sidelines. He quickly took a step and bent down to pick it up. The paper money has a peculiar smell of ink, which makes people can’t help smelling it again and again. When Al Daisy  found that it was a banknote with a high denomination, he began to search for ways to spend this wealth around him and put it in his pocket with a little pride.

Al Daisy  is over 70 years old. He smiled and handed a 5-pound note to the substitute referee who was in charge of placarding on the sidelines, as a thank you for their hard work, as well as encouragement and support. The front and back of the paper money are clearly visible, with exquisite patterns and profound meanings printed on it, which reflects the British culture and historical background. However, the grim-faced 4th official unceremoniously pushed Al Daisy  away, as if everything he did was regarded as nothing. Al Daisy  was embarrassed and helpless. He didn’t expect such a reaction, but he firmly believed that kindness and honesty would be rewarded and recognized.

Al Daisy  returned to the sidelines, with an embarrassed smile on his face and turned to leave. He held a 5-pound note in his hand and handed it to the teaching assistant beside him with emotion. He never thought that the teaching assistant didn’t accept it. Ale Daisy ‘s heart sank slightly, the smile on his face solidified, and he looked puzzled. But he didn’t give up. He turned and walked over to another substitute referee who was in charge of the sideline, trying to hand him this note as a thank-you and support for their hard work. But it was rejected, making Al Daisy  even more helpless. He can’t help but wonder whether these officials really understand and recognize his enthusiasm and sincerity. However, Al Daisy  still firmly believes in his kindness and integrity, and believes that those excellent qualities will always be rewarded and recognized. Therefore, he walked into the field silently, full of love and trust in his heart, and full of confidence and courage even when he was coldly and misunderstood.

Al-Daisy  returned to the sidelines, smiled awkwardly, and handed the 5-pound bill to the teaching assistant beside him with emotion, but was unexpectedly rejected. He didn’t give up, and when he tried to ask another substitute referee who was in charge of the sidelines, he was also rejected. Al Daisy ‘s heart sank slightly, and his face was puzzled. He began to wonder whether officials really understood his enthusiasm and sincerity. In any case, this paper money represents his gratitude and support for his hard work in this competition, so he put it in his wallet, expecting to get due reward and recognition in the future. Al-Daisy  turned away with a little depressed expression, just like the fleeting attack, which made the coach who came to comfort him in a hurry feel a little distressed. He raised his head, reached for the 5-pound note and handed it to the teaching assistant beside him, silently expecting the other person’s approval, but it was rejected. He tried to pass the money to another substitute referee on the sidelines to express his gratitude to the referees for their hard work, but it was also in vain. Al Daisy ‘s brow wrinkled, and he began to wonder whether those officials really understood his enthusiasm and sincerity. However, this 5-pound note still represents his devotion and efforts to the game, so he gently put it into his pocket.

When Al Daisy  left the stadium, he smiled and leaned over to pick up a 5-pound note scattered on the grass. At this time, there are no spectators and players on the field, and this scene seems a bit funny. He held the money in his hand and was deeply moved. This banknote represents his deep love for this Premier League game, and it is also his firm belief and investment in football. He seems to be deeply moved by this seemingly insignificant bill, which is a precious wealth for him. He stroked the bill gently, his eyes soft and focused. At this moment, he seems to have projected his soul on this banknote. In his eyes, this paper money represents a value beyond money. The weight of coins has long been surpassed and changed in his heart, and it has become a deep gratitude and support. This game, he has passed the young and impulsive age, but his inner love for football and passion for the game are still so strong. He put the bill in his pocket, as if it were a precious stone. This banknote will accompany him and witness his unremitting pursuit and investment in football.

Some media made fun of the fact that Al Daisy  picked up the 5-pound note during the competition. ESPN, for example, joked that Al Daisy  was trying to buy off the referee with money, but was firmly rejected. SPORTbible, the account for playing stalk, used a pun. They said that Al Daisy  picked up the money, but it was rejected by the fourth official, so he quickly put it in his pocket. This is an old tradition. In fact, this ironic statement implies a meaning that in the past case of English coach Sam, he was dismissed after just 67 days because of his behavior of allegedly trading power and money with a third party. In this way, these media seem to imply that Al-Daisy ‘s behavior may be inappropriate and needs to be sufficiently vigilant.

In this relegation battle between West Ham and Leeds United, Leeds United coach Al Daisy  found a 5-pound note and became the focus. Al Daisy  handed the money to the fourth official, but the other party refused to accept it, so he put his wallet in his pocket again. Some media hinted at the impropriety of Al-Daisy ‘s behavior by teasing, so there was a lot of discussion in the football circle for a while.

Defeated away, lost two games in a row! If Brother Alphabet doesn’t come back, the Heat will eliminate the Bucks.

The letter brother was injured for two games, which was a great opportunity for Middleton to prove himself. He was scolded in the regular season and had to look for face in the playoffs.

Why Wen is far from disappointing? You said he played well. The team is currently in a disadvantage position. You said he played poorly. The data also has a score of early 20. In the final analysis, it is not a matter of good or bad, but a matter of value or not.

A month ago, Middleton rejected the two-year 80 million renewal contract offered by the Bucks, and then asked for 150 million for three years. The negotiation was not very smooth, and this time it was even more hopeless.

The stag’s basic dish is on the letter brother. If he can play, the stag will flourish. On the contrary, it is mediocre. What matters is not the shooting, but the star. If Middleton insists on getting an annual salary of 50 million, it is very likely to leave the team in the offseason.

Regarding the Heat, we still insist on the previous speculation that losing to the Hawks in the play-off is not a lack of strength, but is deliberately picking the bucks to play, which is also in line with the temperament of this Heat.

Butler is cruel and cruel. You succeeded in revenge in the playoffs. This time, it’s my turn to perform.

Compared with the Celtics, the Heat is really better at fighting bucks. After all, the talent is not so bad, and it will not be too difficult to match.

Everyone in the green army can hold the ball, lock the double flowers and the rest of his teammates come forward. If you play bucks, you just need to focus on taking care of Brother Alphabet, even though Holliday is fierce in the regular season, in fact, the playoffs are also unpredictable.

As for Middleton, as I said at the beginning, it’s ok to be a deputy, but it’s hard to see him lead the team to reverse the direction of the whole series.

The Heat broke Hiro at the start, but there was also good news.

Binbin, who has been put on the trading shelf for many times due to state problems, has come back to life like a dead tree in the playoffs. At present, he made 10 of 13 three-pointers and hit an exaggerated 76.9%. Today, he scored 20 points in 24 minutes on his birthday night.

The lack of scoring points in attack is a long-standing problem for the Heat. It is really crucial that Binbin can stand up and play a role at this time. If he shoots accurately, Butler will feel great and the Heat will be able to return to the park.

If Brother Alphabet still can’t play in the next game, and holds the lead, but also continues to play at home and take down the match point, then the hope of this round of series black eight is very great.

If Black Eight succeeds, it will be another legendary chapter in Butler’s career, and then this matter is really hot.

How can Messi stay in Greater Paris?

In 2023, the Greater Paris Champions League once again became 16 Lang, which is quite sad!

Special size World Cup golden balls and golden boots, is that the level?

No!

Messi’s vision, passing and dribbling are still the top in the world!

Mbappé’s shot, in that year, was still heavy, and he also improved his dribbling skills …

Neymar was in its prime, and Ramos was still domineering. Such a powerful Paris has repeatedly suffered setbacks, which puzzled many readers!

In fact, although Greater Paris is rich, its layman leads the expert, which is the root of the team’s failure!

If they don’t change, Messi and Mbappé will leave!

Brief introduction of Artificial Intelligence (AI)

The development history of Artificial Intelligence (AI) can be traced back to 1950s. The following are the main stages of the development history of AI:

  1. Logical reasoning and problem solving (1950s-early 1960s): The early AI system was based on symbolic logic, and solved problems through logical reasoning of facts and rules. However, this method has limitations, and it is difficult to deal with a large number of uncertain and fuzzy information.
  2. Machine learning and pattern recognition (1960s-1980s): The research of AI began to turn to machine learning and pattern recognition. Machine learning is a method to learn and optimize algorithms by training data, while pattern recognition is a method to realize intelligence by identifying and classifying patterns. These methods have been widely used in image recognition, speech recognition and natural language processing.
  3. Expert system and knowledge representation (1980s-1990s): AI research began to pay attention to expert system and knowledge representation. Expert system is an intelligent system based on expert knowledge and inference rules, which can simulate the decision-making process of human experts. Knowledge representation is a method to organize knowledge and information into a form that can be processed by computer, and it is an important foundation to realize AI.
  4. Statistical learning and deep learning (1990s-2010s): With the continuous development of computer hardware and algorithms, AI research began to pay attention to statistical learning and deep learning. Statistical learning is a machine learning method based on statistical model and data analysis, which can handle a large number of data and complex nonlinear relationships. Deep learning is a machine learning method based on neural network, which can handle more complex and high-dimensional data.
  5. Self-learning and multi-modal AI(2010 to present): AI system is gradually realizing the ability of self-learning and self-optimization, and can continuously improve its own model and algorithm according to feedback and data. Multi-modal AI is an AI technology that can handle a variety of data types and perceptual information, including images, voices, texts, etc., and can realize more comprehensive and intelligent human-computer interaction.

Important events:

  • In 1956, the concept of artificial intelligence was put forward at Dartmouth Conference, which marked the birth of AI.
  • In 1962, Arthur Samuel developed a self-learning program, which was an early application of machine learning.
  • In 1969, Marvin Minsky and Seymour Papert published Perceptrons, which revealed the limitations of single-layer neural networks and promoted the development of neural networks.
  • In 1975, John Holland developed genetic algorithm, which is an optimization algorithm that imitates the process of biological evolution.
  • In 1981, Japan launched the first commercial robot WABOT-1.
  • In 1997, IBM’s deep blue supercomputer defeated Kasparov, the world champion of chess, indicating that computers can surpass human intelligence in some fields.
  • In 2011, IBM’s Watson artificial intelligence system defeated human players in the program "Dangerous Edge".
  • In 2016, AlphaGo defeated Li Shishi, the world champion in the Go competition, marking an important step in the application of artificial intelligence in complex games.
  • In 2018, the GPT-2 model developed by OpenAI made a major breakthrough in the field of natural language processing, which can generate high-quality natural language texts.

The latest development trend:

  1. Self-learning: AI system is gradually realizing the ability of self-learning and self-optimization, and can continuously improve its own model and algorithm according to feedback and data.
