IxDRL: A Novel Explainable Deep Reinforcement Learning Toolkit based on Analyses of Interestingness

1 code implementation18 Jul 2023 Pedro Sequeira, Melinda Gervasio

However, existing systems lack the necessary mechanisms to provide humans with a holistic view of their competence, presenting an impediment to their adoption, particularly in critical applications where the decisions an agent makes can have significant consequences.

A Framework for Understanding and Visualizing Strategies of RL Agents

1 code implementation17 Aug 2022 Pedro Sequeira, Daniel Elenius, Jesse Hostetler, Melinda Gervasio

We present a framework for learning comprehensible models of sequential decision tasks in which agent strategies are characterized using temporal logic formulas.

Outcome-Guided Counterfactuals for Reinforcement Learning Agents from a Jointly Trained Generative Latent Space

no code implementations15 Jul 2022 Eric Yeh, Pedro Sequeira, Jesse Hostetler, Melinda Gervasio

We present a novel generative method for producing unseen and plausible counterfactual examples for reinforcement learning (RL) agents based upon outcome variables that characterize agent behavior.

Interestingness Elements for Explainable Reinforcement Learning: Understanding Agents' Capabilities and Limitations

2 code implementations19 Dec 2019 Pedro Sequeira, Melinda Gervasio

We propose an explainable reinforcement learning (XRL) framework that analyzes an agent's history of interaction with the environment to extract interestingness elements that help explain its behavior.
