STRIDE: Automated Evaluation of Text-to-Trajectory Alignment across Diverse Contexts

The field of language-conditioned trajectory generation is currently hindered by the lack of scalable and reliable evaluation methods. Existing metrics for pedestrian trajectory comparison are limited by their reliance on costly real-world human data collection for each scenario, and they struggle with the heterogeneous and context-dependent nature of pedestrian behavior. A new framework, STRIDE, is introduced to address these challenges by providing the first automated method for evaluating the alignment between scenario descriptions and pedestrian trajectories across diverse contexts.

The development of robust and scalable evaluation methodologies is critical for advancing generative AI capabilities, particularly in domains involving human-like behavior. This innovation could unlock significant progress in areas requiring realistic simulation and predictive modeling of actions based on contextual language, reducing development costs and accelerating innovation cycles.

Current evaluation metrics for language-conditioned trajectory generation are not scalable due to the high cost and infeasibility of collecting human trajectory data for every possible scenario.

Forward consideration, not a verified fact.
