Counterfactual State Explanations for Reinforcement Learning Agents via Generative Deep Learning

2 code implementations29 Jan 2021 Matthew L. Olson, Roli Khanna, Lawrence Neal, Fuxin Li, Weng-Keen Wong

Our second user study investigates if counterfactual state explanations can help non-expert participants identify a flawed agent; we compare against a baseline approach based on a nearest neighbor explanation which uses images from the actual game.

Counterfactual States for Atari Agents via Generative Deep Learning

no code implementations27 Sep 2019 Matthew L. Olson, Lawrence Neal, Fuxin Li, Weng-Keen Wong

In this work, we introduce the concept of a counterfactual state to help humans gain a better understanding of what would need to change (minimally) in an Atari game image for the agent to choose a different action.

Counterfactual Regularization for Model-Based Reinforcement Learning

no code implementations25 Sep 2019 Lawrence Neal, Li Fuxin, Xiaoli Fern

In sequential tasks, planning-based agents have a number of advantages over model-free agents, including sample efficiency and interpretability.
