Nonlinear, distributed, and stochastic model predictive control with GRAMPC-(D/S)

GRAMPC-D provides a modular framework for distributed NMPC of networked systems integrating both optimization and communication, while GRAMPC-S facilitates stochastic NMPC for uncertain systems through different uncertainty propagation methods.

Inference-Time Attention Steering for Vision-Language-Action Driving Models

Vision-language-action (VLA) driving models couple a reasoning stage with a diffusion-based trajectory decoder, but do not give a direct way to redirect attention toward safety-critical actors at inference time without retraining. We studied a bounded additive pre-softmax attention bias on the visual tokens of detector...
