When Visual Signals Mislead: A Mechanistic Study of Attribute Hallucination in Vision-Language Models
Yufei Zhang, Chenlu Zhan, Hongwei Wang
Attribute hallucination---where vision-language models (VLMs) correctly identify an object but mischaracterize its properties---is prevalent yet mechanistically poorly understood.…

SpatialAfford: Teaching Compact VLMs Where to Look and Where to Ground for Affordance

SAD-GS: Learning Reliable 3D Semantic Gaussian Fields via Dynamic Geo-Semantic Anchoring
Yufei Zhang, Chenlu Zhan, Gaoang Wang +1
Open-vocabulary 3D semantic Gaussian field learning relies on multi-view 2D supervision, whose semantic targets and spatial assignments are often unreliable. Across varying viewpoi…
