Cold Fight Master Inventor: Big Challenge Compared to AlphaGo


[Netease Smart News November 9 news] Yesterday, AI World 2017 hosted by Xinzhiyuan held in Beijing. At the meeting, Tuomas Sandholm, professor of Carnegie Mellon University and inventor of the Cold Fighting Master gave a speech explaining the cold. The master's R & D process and future applications.

Tuomas Sandholm stated that the Cold Fight Master is a strategy selection (game theory) program developed using artificial intelligence, and the strategy of the Cold Fight Master is result-oriented.

According to Tuomas Sandholm, there are two major challenges in developing an AI program to play Texas Hold'em, which is the two biggest unknowns. First, it depends on the opportunity for each player in the Texas Hold'em game. “Another unknown is that we don’t know Information about other players, but the opponent does not know our information.” Tuomas Sandholm said that when the Cold Fighter has his own cards, he needs to consider what kind of hints his opponent’s behavior brings, and vice versa. At this time, Cold Fighters will consider balanced real-time calculations.

Tuomas Sandholm has been working on the study of the Cold Fight Master algorithm for the past 13 years and hopes to develop a program to defeat humans. At the beginning of this year, the Cold Fighting Master raced in the Rivers Casino in Pittsburgh and competed with the world's best four no-limit human professional players. He eventually took down four human professional players and took a total of 1.76 million U.S. dollars. The chip's bonus.

So how does the Master of Cold Fight work? Tuomas Sandholm said that first of all, enter the game rules for the Cold Fighter, but unlike AlphaGo, the Cold Fight Master will not learn the history of the past Texas Hold'em because the game is not complete. After inputting the game rules, an abstraction algorithm is used to make an abstract game. Game theory is used, and supercomputers and a large number of GPUs are used for operations. In addition, we must set up a safe subgame, and once it is found to be wrong, it must be amended in time so that the Master of the Cold Fight has greater security. However, Tuomas Sandholm also admits that game theory cannot include all of them. “Including small bets, big bets, and all in. We will also make patches for the follow-up and we will continue to improve the masters of cold blows.” Tuomas Sandholm.

For the future application of the Cold Fighting Master, Tuomas Sandholm said that for deep learning exploration, we will maintain an open degree. In the future, the Cold Fighting Master will also perform more human-computer interactions in addition to the German flutter. In the future, Cold Fighting Masters can be used in many strategic reasonings, such as strategic asset portfolios in the financial sector; they also have their own methods of play in corporate strategies; as well as in auctions, virtual safety, campaigns, autonomous driving strategies, military, and disease prevention. There are great application prospects in infection, training, entertainment and so on. (Small 羿)
