Current methods are typically classified by their supervision types: point-wise, pair-wise, and list-wise. Recent point-wise techniques (e.g., CSQ, MDS) have improved retrieval performance by pre-assigning a hash center to each class, enhancing the discriminability of hash codes across various datasets. However, these methods rely on data-independent algorithms to generate hash centers, which neglect the semantic relationships between classes and may degrade retrieval performance.\n  This paper introduces the concept of sema","authors_text":"Dell Zhang, Li Chen, Rui Liu, Xudong Ma, Yong Chen, Yuxiang Zhou","cross_cats":["cs.AI"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2025-07-11T08:22:27Z","title":"Deep Hashing with Semantic Hash Centers for Image Retrieval"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2507.08404","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:a743292937fde587e49d1489b3dabbf505773efb151a2da7765feef1e6f2a2ad","target":"record","created_at":"2026-07-05T11:35:37Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"e3dff4a45207e982b24d1940f86eb12e2037782dcc550f5ee039891b57b6ece2","cross_cats_sorted":["cs.AI"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2025-07-11T08:22:27Z","title_canon_sha256":"c5adeff1df864151b126871008e84e46310e999a759060ff25af53c4141566cc"},"schema_version":"1.0","source":{"id":"2507.08404","kind":"arxiv","version":1}},"canonical_sha256":"3f9b5a79f4cc1cd964fd388393f6160840d68b0b55017ff9a26dba4bea9c111a","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"3f9b5a79f4cc1cd964fd388393f6160840d68b0b55017ff9a26dba4bea9c111a","first_computed_at":"2026-07-05T11:35:37.499938Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T11:35:37.499938Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"WQb3uH31saASEY9fxK1EzjDXleD0VdJzPqHKJWpXtTdSQXMZg8+AIZQW6qz2Vh/ZjiQr/+MWnslNLsQ6qacXAw==","signature_status":"signed_v1","signed_at":"2026-07-05T11:35:37.500590Z","signed_message":"canonical_sha256_bytes"},"source_id":"2507.08404","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:a743292937fde587e49d1489b3dabbf505773efb151a2da7765feef1e6f2a2ad","sha256:9f5f928a7ccabfbc810a20d1147b9a4da7ec0675f6310aa0ce7f2b64405dec28"],"state_sha256":"cc1976668be2094daa15639cf4730040d904324127885fcde9a51cd76e2f154a"}
