Environment Descriptions for Usability and Generalisation in Reinforcement Learning
Dennis J. N. J. Soemers, Spyridon Samothrakis, Kurt Driessens, Mark H. M. Winands·December 22, 2024
Summary
The paper advocates for a shift in Reinforcement Learning (RL) focus towards user-friendly, domain-specific languages for environment descriptions to enhance usability and generalization. Current practices, involving engineers using general-purpose languages, limit RL's widespread adoption. Language-based descriptions could improve usability and enable agents to generalize better to unseen environments, broadening RL's applicability. The text discusses the need for user-friendly environment descriptions in RL, focusing on domain-specific languages (DSLs) and natural language. It suggests that using DSLs or natural language for environment descriptions could aid in exploring new forms of generalization and transfer in RL, potentially enabling zero-shot transfer to unseen environments. The paper highlights the importance of benchmarks where environments are described in these user-friendly formats to advance RL research and application.
