Whispers from the Neighbors: Rethinking Caption Consensus as Inference-Time Evidence for Vision-Language Retrieval

An image is rarely described only once. Retrieval benchmarks and many collections attach several captions to each picture, yet dual encoders still judge every image-caption pair in isolation. We ask what these neighboring captions contribute when a frozen encoder consults them at inference time. Fusing image similarity...

RA-CoA: Training-free Fashion Image Captioning via Retrieval-Augmented Chain-of-Attributes

RA-CoA is a model-agnostic approach that works with frozen VLMs to improve fine-grained attribute precision in product captions without the need for fine-tuning, and is proposed as a novel, training-free framework that disentangles fashion image captioning into two interpretable stages.
