Tic-Tac-Toe the Hard Way

Yannick and David’s systems play against each other in 500 games. Who’s going to win? And what can we learn about how the ML may be working by thinking about the results?See the agents play each other in Tic-Tac-Two!For more information about the show, check out pair.withgoogle.com/thehardway/.You can reach out to the hosts on Twitter: @dweinberger and @tafsiri. 

David’s variant of tic-tac-toe that we’re calling tic-tac-two is only slightly different but turns out to be far more complex. This requires rethinking what the ML system will need in order to learn how to play, and  how to represent that data.For more information about the show, check out pair.withgoogle.com/thehardway/.You can reach out to the hosts on Twitter: @dweinberger and @tafsiri.

Switching gears, we focus on how Yannick’s been training his model using reinforcement learning.  He explains the differences from David’s supervised learning approach. We find out how his system performs against a player that makes random tic-tac-toe moves.Resources: Deep Learning for JavaScript bookPlaying Atari with Deep Reinforcement LearningTwo Minute Papers episode on Atari DQNFor more information about the show, check out pair.withgoogle.com/thehardway/.You can reach out to the hosts on Twitter: @dweinberger and @tafsiri.
