Decoupling Representation Learning from Reinforcement Learning

3 code implementations • 14 Sep 2020 • Adam Stooke, Kimin Lee, Pieter Abbeel, Michael Laskin

In an effort to overcome limitations of reward-driven feature learning in deep reinforcement learning (RL) from images, we propose decoupling representation learning from policy learning.

Responsive Safety in Reinforcement Learning by PID Lagrangian Methods

no code implementations • 8 Jul 2020 • Adam Stooke, Joshua Achiam, Pieter Abbeel

Lagrangian methods are widely used algorithms for constrained optimization problems, but their learning dynamics exhibit oscillations and overshoot which, when applied to safe reinforcement learning, leads to constraint-violating behavior during agent training.

Perception-Prediction-Reaction Agents for Deep Reinforcement Learning

no code implementations • 26 Jun 2020 • Adam Stooke, Valentin Dalibard, Siddhant M. Jayakumar, Wojciech M. Czarnecki, Max Jaderberg

We employ a temporal hierarchy, using a slow-ticking recurrent core to allow information to flow more easily over long time spans, and three fast-ticking recurrent cores with connections designed to create an information asymmetry.
