UniSteer: Text-Guided Flow Matching in Activation Space for Versatile LLM Steering

Yingdong Shi, Ruiming Zhang, Changming Li +4

Activation-based control steers large language models (LLMs) by intervening on their internal representations during inference, and has emerged as an effective paradigm for control…

SceneReVis: A Self-Reflective Vision-Grounded Framework for 3D Indoor Scene Synthesis via Multi-turn RL

Yang Zhao, Shizhao Sun, Meisheng Zhang +3

Current one-pass 3D scene synthesis methods often suffer from spatial hallucinations, such as collisions, due to a lack of deliberative reasoning. To bridge this gap, we introduce…
