Stuck on Shuffle: On Attribute-Object Binding in Vision-Language Models

Netanel Y. Tamir, Michael Green, Issar Tzachor +4

Retrieval is a fundamental task in multimodal systems: given an image or text query, the goal is to find the most relevant images or texts in a collection, often using a shared emb…
