What is object hallucination?
Object hallucination: A failure of vision-language models in which the answer mentions objects, attributes or text that are not in the image. It arises from strong language priors overriding visual evidence and is measured with benchmarks such as POPE.
Object hallucination: an example
Shown an empty desk, a model describes 'a laptop and a coffee mug' because desks usually have them.
