TL;DR
COMAE introduces a comprehensive attribute exploration framework for zero-shot hashing that leverages locality relationships and continuous attributes, significantly improving retrieval performance on unseen classes.
Contribution
It proposes a novel attribute exploration method with point-wise, pair-wise, and class-wise constraints, enhancing transferability and representation learning in zero-shot hashing.
Findings
Outperforms state-of-the-art methods on ZSH datasets
Effective in scenarios with many unseen classes
Utilizes contrastive learning for attribute context depiction
Abstract
Zero-shot hashing (ZSH) has shown excellent success owing to its efficiency and generalization in large-scale retrieval scenarios. While considerable success has been achieved, there still exist urgent limitations. Existing works ignore the locality relationships of representations and attributes, which have effective transferability between seeable classes and unseeable classes. Also, the continuous-value attributes are not fully harnessed. In response, we conduct a COMprehensive Attribute Exploration for ZSH, named COMAE, which depicts the relationships from seen classes to unseen ones through three meticulously designed explorations, i.e., point-wise, pair-wise and class-wise consistency constraints. By regressing attributes from the proposed attribute prototype network, COMAE learns the local features that are relevant to the visual attributes. Then COMAE utilizes contrastive…
