Source-free Domain Adaptation with Multiple Alignment for Efficient Image Retrieval

ICASSP 2025accepted

Domain adaptation techniques help models generalize to target domains by addressing domain discrepancies between the source and target domain data distributions. These techniques are particularly valuable for cross-domain hashing retrieval, as they reduce training costs while maintaining high retrie…

Effective Comparative Prototype Hashing for Unsupervised Domain Adaptation

AAAI 2024technical

Unsupervised domain adaptive hashing is a highly promising research direction within the field of retrieval. It aims to transfer valuable insights from the source domain to the target domain while maintaining high storage and retrieval efficiency. Despite its potential, this field remains relatively…
