Typically, the proposed OPML first adopts a one-pass triplet construction strategy, which aims to use only a very small number of triplets to approximate the representation ability of whole original triplets obtained by batch-manner methods. Then, OPML employs a closed-form solution to update the metric for new coming samples, which leads to a low space (i.e., $O(d)$) and time (i.e., $O(d^2)$) complexity, where $d$ is the feature","authors_text":"Jing Huo, Lei Wang, Luping Zhou, Wenbin Li, Yang Gao, Yinghuan Shi","cross_cats":["cs.CV"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.LG","submitted_at":"2016-09-29T02:18:06Z","title":"OPML: A One-Pass Closed-Form Solution for Online Metric Learning"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1609.09178","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:b71a392d06d1d0527d4c8fdfc016b4687bc9f6cacaaed7cc8059807a2a89b85e","target":"record","created_at":"2026-05-18T01:03:38Z","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":"1237e5acd43b954c308e1fbded2e2ab0b10dd0fa0ac7cc0bc84026cf1aa571c4","cross_cats_sorted":["cs.CV"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.LG","submitted_at":"2016-09-29T02:18:06Z","title_canon_sha256":"428582a6b726389e868ee94815eb561c234cd70ac51d9cffa26cde39d4adefce"},"schema_version":"1.0","source":{"id":"1609.09178","kind":"arxiv","version":1}},"canonical_sha256":"611ef8afa6b9b366cd569cafca4c57aa7c3348c6d9eec2a7920c6391beeb0ca2","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"611ef8afa6b9b366cd569cafca4c57aa7c3348c6d9eec2a7920c6391beeb0ca2","first_computed_at":"2026-05-18T01:03:38.578448Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:03:38.578448Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"D5DNqUMWPUSqZ2WVAVF9J2AyOZfsdIVUDIW6sE6T2Fh8CMRsVf4w+eALv7XNoKfbKjL3rFrTHP8yFHjpf2r5CQ==","signature_status":"signed_v1","signed_at":"2026-05-18T01:03:38.578964Z","signed_message":"canonical_sha256_bytes"},"source_id":"1609.09178","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:b71a392d06d1d0527d4c8fdfc016b4687bc9f6cacaaed7cc8059807a2a89b85e","sha256:d567cbbeeaaed37e5912adcdd4862ea1aa484fad59190be98675648734235269"],"state_sha256":"e15936f1798cd629362da08c94594160b629c9cf5f3e8444a089f930225e29db"}
