AI Technical Summary

Technical Problem

Existing deep learning trajectory prediction models have uninterpretability and safety risks in unmanned systems, especially when perturbations are added to the trajectory prediction, causing the predicted trajectory to deviate significantly, making it difficult to assess the reliability of the model.

Method used

A multi-source data fusion-based approach is adopted. The model is trained by constructing a trajectory prediction dataset to generate an adversarial example set. An improved gradient attack algorithm and an attention-guided loss function are used to screen out the consistent adversarial examples with the largest average displacement error for credibility assessment.

Benefits of technology

Effective detection and evaluation of the reliability of trajectory prediction models for unmanned systems ensures that they make reasonable decisions in complex environments, thereby improving the robustness of the models and the relevance of the evaluation.
