Learning interpretable generalizable models of sequential decision-making agents is essential for user-driven assessment as well as for continual agent-design processes in several AI applications. Discovering an agent's broad capabilities in terms of concepts a user understands and summarizing them for a user is a comparatively new solution approach for agent assessment. Prior work on this topic focuses on deterministic settings, or settings where the name of agent's capabilities are already known, or situations where the learning system has access to only passively collected data regarding the agent's behavior. These settings result in a limited scope and/or accuracy of the learned models. This paper presents an approach for discovering a black-box sequential decision making agent's capabilities and interactively learning an interpretable model of the agent in stochastic settings. Our approach uses an initial set of observations to discover the agent's capabilities and a hierarchical querying process to learn a probability distribution of the discovered stochastic capabilities. Our evaluation demonstrates that our method learns lifted SDM models with complex capabilities accurately.
