Beyond Logit Lens: Contextual Embeddings for Robust Hallucination Detection & Grounding in VLMs

The rapid development of Large Multimodal Models (LMMs) has significantly advanced multimodal understanding by harnessing the language abilities of Large Language Models (LLMs) and integrating modality-specific encoders. However, LMMs are plagued by hallucinations that limit their reliability and ad…
