Enabling Adaptive Agent Training in Open-Ended Simulators by Targeting Diversity

NeurIPS 2024poster

The wider application of end-to-end learning methods to embodied decision-making domains remains bottlenecked by their reliance on a superabundance of training data representative of the target domain. Meta-reinforcement learning (meta-RL) approaches abandon the aim of zero-shot *generalization*—the…

Possibility Before Utility: Learning And Using Hierarchical Affordances

ICLR 2022spotlight

Reinforcement learning algorithms struggle on tasks with complex hierarchical dependency structures. Humans and other intelligent agents do not waste time assessing the utility of every high-level action in existence, but instead only consider ones they deem possible in the first place. By focusing…
