Project Malmo was initiated by Microsoft Research as a platform to use Minecraft as an AI testing ground. It's not about playing the game, it's about using Minecraft as an experimental AI platform. In the talk, Lars is going to take a look into reinforcement learning and how to solve individual problems with (deep) reinforcement learning, Minecraft, and project Malmo.
