Re-Weighting Cross-Modal Pairs via Rank Consistency for Noise-Robust Retrieval

A novel semantic matching degree estimation method based on ranking consistency that reweights the training paris by measuring the Normalized Discounted Cumulative Gain (NDCG) between its cross-modal and intra-modal retrieval results.

PACE: Progressive Angular-to-Norm Contrastive Embedding

Multimodal embedding models encode heterogeneous inputs into a shared embedding space, enabling efficient similarity computation across modalities and tasks. Most existing methods optimize cosine-based contrastive objectives, which promote stable training but restrict semantic compatibility to angular geometry, preclud...
