Policy-Guided Diffusion

1 code implementation9 Apr 2024 Matthew Thomas Jackson, Michael Tryfan Matthews, Cong Lu, Benjamin Ellis, Shimon Whiteson, Jakob Foerster

Our approach provides an effective alternative to autoregressive offline world models, opening the door to the controllable generation of synthetic training data.

Discovering Temporally-Aware Reinforcement Learning Algorithms

1 code implementation8 Feb 2024 Matthew Thomas Jackson, Chris Lu, Louis Kirsch, Robert Tjarko Lange, Shimon Whiteson, Jakob Nicolaus Foerster

We propose a simple augmentation to two existing objective discovery approaches that allows the discovered algorithm to dynamically update its objective function throughout the agent's training procedure, resulting in expressive schedules and increased generalization across different training horizons.

Hypernetworks in Meta-Reinforcement Learning

1 code implementation20 Oct 2022 Jacob Beck, Matthew Thomas Jackson, Risto Vuorio, Shimon Whiteson

In this paper, we 1) show that hypernetwork initialization is also a critical factor in meta-RL, and that naive initializations yield poor performance; 2) propose a novel hypernetwork initialization scheme that matches or exceeds the performance of a state-of-the-art approach proposed for supervised settings, as well as being simpler and more general; and 3) use this method to show that hypernetworks can improve performance in meta-RL by evaluating on multiple simulated robotics benchmarks.
