Causal reasoning in RL faces challenges with corrupted data, article finds

A new article explores the challenges of integrating causal reasoning into reinforcement learning (RL) agents. While causal models promise enhanced generalization and intervention capabilities for RL, they can also lead to worse performance than standard correlation-based methods if the learned causal graph is incorrect. The article highlights that data collected by an RL agent's policy can corrupt the causal discovery process, making certain causal relationships statistically invisible. This work aims to clarify when causal models benefit RL practitioners and researchers, particularly in non-stationary environments. AI
