What "Not" to Detect: Negation-Aware VLMs via Structured Reasoning and Token Merging

Inha Kang, Youngsun Lim, Seonho Lee +3

State-of-the-art vision-language models (VLMs) suffer from a critical failure in understanding negation, often referred to as affirmative bias. This limitation is particularly seve…
