Competition for 'AI vs AI' ... Compete for how much more human.

"Which of the two of you wrote glasses?" "Where is the child sitting?"


The '2018 Computer Vision Pattern Recognition Society (CVPR)' held in Salt Lake City, Utah, USA, last June. Whenever the two pictures and the question to distinguish them appeared, there was tension. It was the scene where the AI ​​was judged by the AI ​​and won the final winner of the AI ​​Visual Question and Answer Competition, which selects the pictures that match the question. The winner of the day was a team with 72.41 points. The research team of professor Jeong Byeong-tuck of Seoul National University received 71.69 points and came in second place.


◆ Now, the 'competition period between AI'


The evolution of AI is closely related to the contest. Deep learning, the mainstream technology, was first noticed in the image recognition contest 'ILSVRC' in 2012. The 'Super Vision' team led by Professor Jeffrey Hinton of Canada at the time won the championship with an overwhelming difference using deep learning technology. When other teams went up and down the error rate by 26%, the error rate was reduced to 15.3%. In 2012, ILSVRC became a milestone in AI history. Major global information technology (IT) companies have invested heavily in AI.


Since then, AI technology has become even stronger through the contest. In the early days, events where people and AI stood out were popular. In March 2016, the pro-goalkeeper Lee Sedol 9th ​​stage and the AI ​​program Alpha Go-go Bad confrontation are representative cases.


Recently, there are a lot of contests which are more 'AI vs AI' than 'people vs AI'. It is said that the competence of AI is so many that it has overtaken people. First and foremost, Chess was a baduk with a throne in AI. The first factor in these three areas is Alpha Zero, an upgraded version of AlphaGo. Alpha Zero defeated all the strongest AIs in less than a day in December last year. At the time, the AIs were confronted with Algo at Elmo, which won the World Computer Championships, Stockfish, which was at the top of the chess AI World Championship, and Alpha Gozo, the previous version of the goalkeeper.




In recent years, there has been a tendency to narrow down the types of events that AI races against each other. On the 22nd, KAIST held the 'AI World Cup', the world's first to host soccer games in the form of tournaments between AIs. Five icons with numbers from 0 to 4 were used to automatically play soccer games. There was a game rule that if the icon of the ball stopped for 2.5 seconds, it was temporarily withdrawn, and all the icons did not move for 5 seconds.


It is not just football games that attracted attention at AI World Cup. There was also interest in the 'AI reporter' competition, which automatically writes articles about the game. The AI ​​who participated in this division recognized the game contents and automatically placed the "optimal sentence" with the information based on the existing sports articles. A simple sentence structure proves that no more people are needed.


On the 21st, GIST (Gwangju Institute of Science and Technology) held 'StarCraft 2 AI Global War'. Five teams from five countries came to the finals and played StarCraft 2 in an automated fashion. GIST's "G-SCAI Bot" won the final game in the match.


◆ 'AI gamer' is evolving


There are still areas where AI does not cross human. Online games such as StarCraft and DotA 2 are representative.


On the 23rd, the Dota 2 global tournament, Dota 2 International, hosted two matches between AI and a team of Brazilian team Tim Payne. It was the open AI of the non-profit artificial intelligence research institute invested by Ilron Musk, which developed 'Open AI Five' in the game.


The Open AI Five had a skilled performance, including winning a one-on-one match with a man before. Because of this, experts have seen the possibility of winning AI more than humans. But the result was the opposite. When the game started, AI made a rudimentary mistake, such as not being able to form a team for attacking properly. The second half of the game was also inexperienced. Open AI said, "AI played in anticipation of the result after 14 minutes, but there was not enough action after that."


AI was defeated in the StarCraft showdown with pro-gamer Song Byung-koo in last year's Seoul Sejong University. Song Byung-gu won all four AIs, including the MJ bot developed by Sejong University research team and ZZZK of Australia. These AIs won the game against amateur players, but did not seem to be able to beat the top professional gamers. It is a proof that AI technology is not complete yet.
