Adaptive Safety Filtering for Frozen ACC Policies via Conformal Residual Calibration

Zhiruo Zhou, Rigaudiere Z. Li, Chen Xiwen وآخرون · 2026

Frozen adaptive cruise control (ACC) policies can violate constraints when deployment dynamics differ from their training conditions. We propose residual-aware conformal action filtering (RACF), which calibrates residuals of a fixed nominal predictor and converts their quantile into an operating margin for finite-model …

Frozen Flows Forget: Diagnosing and Restoring Lost Motion in a Latent-flow World Model

Xiwen Chen, Rigaudiere Z. Li, Zhiruo Zhou وآخرون · 2026

Latent world models that integrate a flow in a frozen self supervised latent space train stably and cheaply, yet silently lose the property manipulation depends on most: motion. The pretrained flow never moves the manipulated object; retraining it with latent-only losses only trades stillness for teleport-like motion. …
