Proposing a Policy Characteristic Space for discrete agent strategies while maintaining continuous control.
Abstract
The paper introduces a novel approach to address the challenge of generating competitive strategies and performing continuous motion planning in adversarial settings. By mapping agent policies to a low-dimensional space called Policy Characteristic Space, the method enables discretization of agent policy switchings while preserving continuity in control. This approach enhances interpretability of agent actions and intentions, leading to improved performance in adversarial environments, as demonstrated through experiments in an autonomous racing scenario. The study also highlights the significance of game-theoretic approaches for continuous motion planning.
