Agent Trajectory Analysis

Ask about this topic

Overview

Agent trajectory analysis examines sequences of actions or movements, from autonomous vehicles and pedestrians to language-model agents using tools. Methods include social and physics-guided motion prediction, trace and graph representations, step-level evaluation, and attribution of failures or reusable behaviors. Benchmarks and trajectory-level measures reveal inefficiency, unsafe steps, and procedural differences that final success scores can miss. A central challenge is reliably connecting events across long histories to outcomes, while balancing detailed diagnosis with scalable, efficient evaluation.
