Researchers have introduced SOLAR, a novel self-supervised framework designed for symmetric multimodal retrieval tasks where queries and contexts can be interchanged. This two-stage approach utilizes unlabeled image-text pairs from the web to learn alignments and discrepancies between modalities. SOLAR constructs positive and hard-negative samples by masking parts of images or text, enabling effective multimodal embedding learning. The framework reportedly outperforms supervised methods on a new benchmark, using significantly fewer parameters and a smaller embedding dimension. AI
