Evolution Strategies at the Hyperscale

Bidipta Sarkar, Mattie Fellows, Juan Agustin Duque +17

Evolution Strategies (ES) is a class of powerful black-box optimisation methods that are highly parallelisable and can handle non-differentiable and noisy objectives. However, naïv…

Imagined Autocurricula

Ahmet H. Güzel, Matthew Thomas Jackson, Jarek Luca Liesen +4

Training agents to act in embodied environments typically requires vast training data or access to accurate simulation, neither of which exists for many cases in the real world. In…

A Clean Slate for Offline Reinforcement Learning

Matthew Thomas Jackson, Uljad Berdica, Jarek Liesen +2

Progress in offline reinforcement learning (RL) has been impeded by ambiguous problem definitions and entangled algorithmic designs, resulting in inconsistent implementations, insu…

Behaviour Distillation

Andrei Lupu, Chris Lu, Jarek Liesen +2

Dataset distillation aims to condense large datasets into a small number of synthetic examples that can be used as drop-in replacements when training new models. It has application…

Discovering Minimal Reinforcement Learning Environments

Jarek Liesen, Chris Lu, Andrei Lupu +3

Reinforcement learning (RL) agents are commonly trained and evaluated in the same environment. In contrast, humans often train in a specialized environment before being evaluated,…
