Abstract
Recorded 16 February 2022. Lisa Lee of Google Brain presents "Learning to Explore with Scalable Supervision" at IPAM's Mathematics of Collective Intelligence Workshop. Abstract: Reinforcement learning (RL) agents learn to perform a task through trial-and-error interactions with an initially unknown environment. Despite the recent progress in deep RL, several unsolved challenges limit the applicability of RL to real-world tasks, including efficient exploration in high-dimensional spaces, learning efficiency, safety, and the high cost of human supervision. Towards solving these challenges, this talk focuses on how we can balance self-supervised and human-supervised RL to efficiently train an agent for solving various robotic continuous control tasks. We address the following questions: 1. How can we amortize the cost of learning to explore? 2. How can we learn a semantically meaningful representation for faster exploration and learning? 3. Can we distill exploration into a reusable reward function?
