A system that improves image searches without any training, using concept memory.

Searching for a target picture using a starting image and text instructions is tricky. Standard search tools find an initial group of images, but they can still miss the mark. To fix this, researchers built AutoConcept, a system that reranks these results without extra training. It works by turning text descriptions and details into an easy-to-read concept memory. It filters out useless ideas, applies matching positive rules, penalizes negative traits, and blends these checks with the original scores. When tested on FashionIQ, it brought the best images much closer to the top across two different base retrieval pools. It beat simple text or attribute matching and worked well with human-provided labels, making it a reliable way to organize product searches.
