From Suppression to Repair: Mitigating Object Hallucination in Large Vision-Language Models via Localized Distribution Alignment

Chen Zhao, Xingping Dong, Jiachun Shi وآخرون · 2026

Object hallucination remains a major obstacle for large vision-language models (LVLMs) to generate reliable content. An intuitive mitigation strategy is to suppress hallucination-related components in hidden representations. However, these components may also contain useful information, and suppressing them can weaken …

Beyond Retrieval Relevance: Scene-Grounded Risk Entailment for Vision-Language Driving

Jiaxin Liu, Ruilin Yu, Liang Peng وآخرون · 2026

Retrieval-augmented generation (RAG) gives vision--language driving systems access to external safety knowledge, yet a retrieved risk rule may be relevant without applying to the current scene. A vision--language model (VLM) receiving such knowledge must ground objects, bind entities across time, and verify relations b …

PGL-3D: Towards Progressive Geometric Learning for 3D Visual Query Localization

Liang Peng, Shizhuo Mu, Bohan Tan وآخرون · 2026

3D Visual Query Localization (3DVQL) retrieves the latest contiguous occurrence of a queried object in an RGB--point-cloud sequence and predicts a 9-DoF cuboid for every response frame. The query is captured independently of the search sequence, so its annotated pose may differ from how the object appears in the search …
