MARS framework improves text-video retrieval using multimodal LLMs

Researchers have developed MARS, a novel framework designed to enhance text-video retrieval by leveraging multiple layers and adaptive representation slots from multimodal large language models. Unlike existing methods that often compress diverse cues into a single vector, MARS constructs multiple slots by combining hidden states from different decoder layers. This approach allows for a more nuanced comparison of text and video elements, with experiments demonstrating state-of-the-art results on several benchmarks. The framework further incorporates a hard-negative-aware slot specialization objective to improve the capture of discriminative matching cues, leading to significant gains in both direct similarity-based retrieval and reranking.
