Why reinforcement learning breaks at scale, and how a new method fixes it

From autonomous cars to video games, reinforcement learning (machine learning through interaction with environments) can have an important impact. That may feel especially true, for example, when you're a passenger late for dinner in an autonomous car that has learned the efficient way home. Work in Jr-Shin Li's lab develops mathematically rigorous and computationally efficient techniques to transform extremely complex reinforcement learning problems into a manageable domain.
