We train our network in a supervised way by fully\nexploiting inter-class diversity and intra-class identity. Classification loss\nis optimized to maximize inter-class diversity, while intra-pair is introduced\nto learn representative intra-class identity. We investigate the binary bits\ndistribution related to categories and find out that the effectiveness of\nbinary bits is highly correlated with data categories, and some bits may\ndegrade classification performance of some categories. We then design hash code\ngeneration scheme with category mask to filter out bits with negative\ncontribution. Experimental results demonstrate the proposed method outperforms\nseveral state-of-the-arts under various evaluation metrics on public datasets.","url_abs":"http://arxiv.org/abs/1712.08315v2","url_pdf":"http://arxiv.org/pdf/1712.08315v2.pdf","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","row_kind":"abstracts"},"code_links":[{"paper_slug":"deep-hashing-with-category-mask-for-fast","repo_url":"https://github.com/willard-yuan/hashing-baseline-for-image-retrieval","is_official":1,"mentioned_in_paper":1,"mentioned_in_github":1,"framework":"none","reach":null}],"tasks":[{"task_slug":"code-generation","task_name":"Code Generation"},{"task_slug":"deep-hashing","task_name":"Deep Hashing"},{"task_slug":"diversity","task_name":"Diversity"},{"task_slug":"classification","task_name":"General Classification"},{"task_slug":"retrieval","task_name":"Retrieval"},{"task_slug":"video-retrieval","task_name":"Video Retrieval"}],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"syntology_url":null,"atlas_url":null,"mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
