Researchers have developed MiMIC, a novel approach to Universal Multimodal Retrieval (UMR) that addresses issues of visual modality collapse and semantic misalignment. Unlike previous methods that either fuse modalities early or late, MiMIC employs a fusion-in-decoder architecture. It also incorporates robust training techniques, including single modality mixin and random caption dropout, to improve performance on datasets like WebQA+ and EVQA+. AI
