Applying existing chess engines to this data, including an open-source implementation of AlphaZero, we find that they do not predict human moves well. The hundreds of millions of games played online by players at every skill level form a rich source of data in which these decisions, and their exact context, are recorded in minute detail.

The aggregate performance of a chess player unfolds as they make decisions over the course of a game. We pursue this goal in a model system with a long history in artificial intelligence: chess. A crucial step in bridging this gap between human and artificial intelligence is modeling the granular actions that constitute human behavior, rather than simply matching aggregate human performance. However, the ways in which AI systems approach problems are often different from the ways people do, and thus may be uninterpretable and hard to learn from. The code for training Maia can be found on our Github Repo.Īs artificial intelligence becomes increasingly intelligent-in some cases, achieving superhuman performance-there is growing potential for humans to learn from and collaborate with algorithms. If you want to see some more examples of Maia's predictions we have a tool here to see where the different models disagree. If you want to be the first to know, you can sign up for our email list here. We are going to be releasing beta versions of learning tools, teaching aids, and experiments based on Maia (analyses of your games, personalized puzzles, Turing tests, etc.). You can read a blog post about Maia from the Computational Social Science Lab or Microsoft Research. Read the full research paper on Maia, which was published in the 2020 ACM SIGKDD International Conference on Knowledge Discovery and Data Mining (KDD 2020).
