Title: A glimpse at reinforcement learning through the eyes of a theoretician
Abstract: Reinforcement learning (RL) is at the heart of a number of exciting recent developments in artificial intelligence. In 2013, RL was used to create a computer program that was shown to be able to play about 60 computer video games developed for a game console from the 1980s, achieving better scores than an average human does, while using the same inputs and controls than humans use. Shortly after, RL was also used to create a computer program that decisively defeated the best human player at the game of Go. In both cases, experts thought that creating these programs will take much more time and were especially skeptical of the value of an RL based approach to tackle these problems. After these successes, similar successes have been achieved in numerous other domains. Yet, RL has been around since for a long time. The basic ideas behind RL go back to the work of Richard Bellman and his coworkers, who worked on the fundamental problem that RL algorithms tackle in the 1960s. Of course, over the decades since then, computers got many orders of magnitudes faster, while recent years have also witnessed an even faster increase of investments into using computers (and in particular RL) to solve various problems. In this talk, I will explain the basic problem that RL tackles, the basic ideas that power today's RL algorithms, while I will also explain the foundational theoretical challenges behind all this. I will then connect the dots by speculating a little on how the foundational barriers were overcome in the previously mentioned examples and then close with a few open questions that would be important to address.

We hope to see you all on the 23rd!
