The Hanabi Challenge: A New Frontier for AI Research Machine Learning

From the early days of computing, games have been important testbeds for studying how well machines can do sophisticated decision making. In recent years, machine learning has made dramatic advances with artificial agents reaching superhuman performance in challenge domains like Go, Atari, and some variants of poker. As with their predecessors of chess, checkers, and backgammon, these game domains have driven research by providing sophisticated yet well-defined challenges for artificial intelligence practitioners. We continue this tradition by proposing the game of Hanabi as a new challenge domain with novel problems that arise from its combination of purely cooperative gameplay and imperfect information in a two to five player setting. In particular, we argue that Hanabi elevates reasoning about the beliefs and intentions of other agents to the foreground. We believe developing novel techniques capable of imbuing artificial agents with such theory of mind will not only be crucial for their success in Hanabi, but also in broader collaborative efforts, and especially those with human partners. To facilitate future research, we introduce the open-source Hanabi Learning Environment, propose an experimental framework for the research community to evaluate algorithmic advances, and assess the performance of current state-of-the-art techniques.

Bested by AI: What Happens When AI Wins?


A few months ago, I sent my dad the article 20 Top Lawyers Were Beaten by Legal AI in a Controlled Study, which (as the title suggests) discusses a study on how AI can be applied to the field of law, and how it performs against professional lawers. An implication of this article is the potential to replace lawyers with AI for many common legal needs, such as contract review or writing wills. It's an interesting article and application of AI, which I spend a lot of time thinking about. It might seem pretty innocent that I shared it with my dad, and it would be, except that my dad is a lawyer. Yes, I was kind of trying to get a rise out of him (it's all affectionate, I promise).

A Gamut of Games

In Shannon's time, it would have seemed Around this time, Arthur Samuel began work the capabilities of computational intelligence. By 1958, Alan Newell and Herb Simon the game world with the real world--the game had begun their investigations into chess, of life--where the rules often change, the which eventually led to fundamental results scope of the problem is almost limitless, and for AI and cognitive science (Newell, Shaw, and the participants interact in an infinite number Simon 1958). An impressive lineup to say the of ways. Games can be a microcosm of the real least! Indeed, one of the early goals of AI was to and chess programs could play at a build a program capable of defeating the level comparable to the human world champion. This These remarkable accomplishments are the challenge proved to be more difficult than was result of a better understanding of the anticipated; the AI literature is replete with problems being solved, major algorithmic optimistic predictions. It eventually took insights, and tremendous advances in hardware almost 50 years to complete the task--a technology. The work on computer remarkably short time when one considers the games has been one of the most successful and software and hardware advances needed to visible results of AI research. The results are truly of the progress in building a world-class amazing. Even though there is an exponential program for the game is given, along with a difference between the best case and the brief description of the strongest program. The histories are necessarily case (Plaat et al. 1996). Games reports the past successes where computers realizing the lineage of the ideas.
