ERCI: An Explainable Experience Replay Approach with Causal Inference for Deep Reinforcement Learning

AAAI 2025technical

Deep reinforcement learning (DRL) has gained significant attention in autonomous systems, yet its black-box nature and lack of explainability hinder user trust in safety-critical domains such as autonomous driving. Existing experience replay approaches enhance sample efficiency but often fail to cap…

Exogenous Matching: Learning Good Proposals for Tractable Counterfactual Estimation

NeurIPS 2024poster

We propose an importance sampling method for tractable and efficient estimation of counterfactual expressions in general settings, named Exogenous Matching. By minimizing a common upper bound of counterfactual estimators, we transform the variance minimization problem into a conditional distribution…
