arXiv:2606.20280v1 Announce Type: cross Abstract: Leveraging Multimodal Large Language Models (MLLMs) via contrastive learning has become a mainstream paradigm for improving the performance of Universal Multimodal Retrieval (UMR). However, previous works have ignored the grain blindness when adapting the contrastive paradigm into retrieval tasks. Grain blindness refers to the tendency of the model to overlook grain-level information contained in the query, which is crucial for effectively handling complex queries. This stems from contrastive learning treating samples as a binary classification
The paper addresses a current limitation in Multimodal Large Language Models (MLLMs) being adapted for retrieval tasks, highlighting new advancements and refinements in AI research.
Improving Universal Multimodal Retrieval enhances the accuracy and efficiency with which AI systems can process and understand complex queries across different data types, crucial for advanced AI applications.
This research suggests a shift in how contrastive learning is applied to multimodal retrieval, moving towards methods that can better discern 'grain-level' information in queries, leading to more nuanced and effective retrieval systems.
