On the Steering Dimensionality of Refusal in Language Models

Han Wang, Erik Miehling, Dennis Wei وآخرون · 2026

Existing activation steering methods often assume that a high-level concept can be mediated by a single steering direction. To support this, two complementary interventions should be achieved: additive steering should induce the target behavior, while directional ablation should suppress it. Yet behaviors may occupy ri …

MotorMind: Scaffolding General Vision Language Models for Zero-Shot Robot Manipulation

Bingxuan Li, Siqi Song, Yizhuo Wu وآخرون · 2026

Vision-language-action (VLA) models have advanced robotic manipulation, but their zero-shot generalization in new tasks and environments remains limited, and their reliance on specialized training keeps them from benefiting directly from rapidly advancing general-purpose vision-language models (VLMs). In parallel, rece …
