Publication number: 20250091618Abstract: In various examples, a trajectory prediction model provides interpretable trajectory predictions for autonomous and semi-autonomous systems and applications via counterfactual game-theoretic reasoning. Model-based latent variables can be formulated through responsibility evaluations. Responsibility can be broken into multiple components, such as safety and courtesy. Responsibility can be quantified, for example, by answering a counterfactual question: could an agent have executed differently to respect other agents' safety and be more courteous to others' plans? The framework can be used to abstract computed responsibility sequences into different responsibility levels and ground latent levels into a trajectory prediction model able to render interpretable and accurate inferences about trajectory.Type: ApplicationFiled: September 20, 2023Publication date: March 20, 2025Applicant: NVIDIA CorporationInventors: Yuxiao CHEN, Kai-Chieh HSU, Karen Yan Ming LEUNG, Marco PAVONE
