Disentangling Hallucinations: Orthogonal Semantic Projection for Robust Interpretability

arXiv:2606.14758v1 Announce Type: cross Abstract: As Vision-Language Models are increasingly deployed in safety-critical applications, the trustworthiness of their explanations becomes crucial. Explainable AI (XAI) methods for Vision-Language Models often suffer from semantic hallucination, where attribution maps highlight prominent image regions even when prompted with incorrect text descriptions (e.g., highlighting a dog when prompted ``cat''). Although this problem is widespread, a formal mathematical analysis of XAI methods and CLIP embeddings is largely missing in the literature. We demon

Why this matters
Why now

The increasing deployment of Vision-Language Models (VLMs) in critical applications necessitates robust interpretability to ensure trustworthiness.

Why it’s important

Semantic hallucination in VLM explanations undermines confidence and reliability, hindering adoption in safety-critical domains such as medical diagnostics or autonomous systems.

What changes

Improved mathematical frameworks for understanding and mitigating VLM hallucination can lead to more trustworthy and deployable AI systems.
