Statistical Model-driven Similarity Hashing: Bridging Modalities for Efficient Unsupervised Retrieval
AAAI 2025technical
Unsupervised deep cross-modal hash retrieval aims to map multi-modal features into binary hash codes without labels, which is of interest due to its storage efficiency, query speed and convenient applications. However, existing approaches suffer from two main limitations: (1) Slightly insufficient c…
