Kernel-Based Metrics Learning for Uncertain Opponent Vehicle Trajectory Prediction in Autonomous Racing

Read the original on arXiv AI →

The paper introduces heterogeneous kernel metrics for Deep Kernel Learning to predict uncertain opponent vehicle trajectories in autonomous racing. By aligning similar driving policies and separating dissimilar ones in an unsupervised way, the method improves prediction accuracy and enables safer overtaking. Experiments on a 1/10th scale racecar platform confirm the approach’s effectiveness and computational efficiency for onboard units.

Reinforcing End-to-End Autonomous Driving Safety via Negative-Aware Planning in a Unified World-Action Model

The paper introduces NegWAM, a safety post‑training framework for unified world‑action models (WAMs) used in end‑to‑end autonomous driving. NegWAM generates negative trajectories that are close to expert paths but contain safety risks, using them as repulsive anchors to steer predictions away from dangerous behavior while encoding scene‑trajectory compatibility via rider tokens. The method achieves a 4.1% relative improvement on the NAVSIM v2 navhard benchmark and 93.3 EPDMS on navtest, demonstrating strong safety performance without sacrificing routine driving, and shows cross‑benchmark generalization in zero‑shot closed‑loop tests on HUGSIM.
