SaFeR: Safety-Critical Scenario Generation for Autonomous Driving Test via Feasibility-Constrained Token Resampling

SaFeR is a novel framework for generating safety-critical autonomous driving test scenarios that balances adversarial criticality, physical feasibility, and behavioral realism by employing a Transformer-based realism prior with a differential attention mechanism and a feasibility-constrained token resampling strategy derived from offline reinforcement learning.

Learning Hip Exoskeleton Control Policy via Predictive Neuromusculoskeletal Simulation

This paper presents a physics-based neuromusculoskeletal learning framework that trains a hip-exoskeleton control policy entirely in simulation using reinforcement learning and muscle-synergy priors, successfully transferring the policy to hardware without motion-capture data or additional tuning while achieving significant reductions in muscle activation and joint power across diverse walking conditions.
