Most of the unsupervised hashing methods learn to map images into semantic similarity-preserving hash codes by constructing local semantic similarity structure from the pre-trained model as the guiding information, i.e., treating each point pair similar if their distance is small in feature space. However, due to the inefficient representation ability of the pre-trained model, many false positives and negatives in local semantic similarity will be introduced and lead to error p","authors_text":"Chong Chen, Daqing Wu, Jianqiang Huang, Jinwen Ma, Minghua Deng, Xian-Sheng Hua, Xiao Luo, Zeyu Ma, Zhongming Jin","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2020-10-15T14:47:14Z","title":"CIMON: Towards High-quality Hash Codes"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2010.07804","kind":"arxiv","version":4},"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":"sha256:714e507f1c26a38a91173dca938d66b181cb41d3fe60c5b495d044e34681a067","target":"record","created_at":"2026-07-05T03:07:44Z","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":"dd9944054bc6992ca56beb157e15ba9ebd5161e44dce3d94fcdf72048fd10004","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2020-10-15T14:47:14Z","title_canon_sha256":"a47d9d0c9a26434047e90071e909a76d1fdefde3729cbfbb38c8f1e6d929f7eb"},"schema_version":"1.0","source":{"id":"2010.07804","kind":"arxiv","version":4}},"canonical_sha256":"12f56d9c34874f4c6f98a58eec3929fd4fdc5cb463027efc3d94841b5b34d022","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"12f56d9c34874f4c6f98a58eec3929fd4fdc5cb463027efc3d94841b5b34d022","first_computed_at":"2026-07-05T03:07:44.593792Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T03:07:44.593792Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"fcTcTUI5XQfWiqwqRzLdV4k5Y0Kn+xkRYPiMRE50b3mLcBqhjIMvbJiLwdHMLf7JAfz8YdQ42r811g+pbdEgCw==","signature_status":"signed_v1","signed_at":"2026-07-05T03:07:44.594165Z","signed_message":"canonical_sha256_bytes"},"source_id":"2010.07804","source_kind":"arxiv","source_version":4}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:714e507f1c26a38a91173dca938d66b181cb41d3fe60c5b495d044e34681a067","sha256:1d33d3a360a89e53f52f6d11bc14dcbe3ef2e4b0df93b1ad7b5f423efb9fa8e3"],"state_sha256":"24d4d0bf328d424e11e2e36b1d089cd91c7634a3579b6cfb3b522d4fe0587eaa"}
