For most existing learning to hash methods, sufficient training images are required and used to learn precise hashing codes. However, in some real-world applications, there are not always sufficient training images in the domain of interest. In addition, some existing supervised approaches need a amount of labeled data, which is an expensive process in term of time, label and human expertise. To handle such problems, inspired by transfer learning, we propose ","authors_text":"Ji Liu, Lei Zhang","cross_cats":["cs.CV","cs.LG"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.IR","submitted_at":"2019-03-01T11:43:31Z","title":"Optimal Projection Guided Transfer Hashing for Image Retrieval"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1903.00252","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":"sha256:626807fcb28cd06adef8e76ed44699b17f682cbfd41faf2fd447e0312a17c400","target":"record","created_at":"2026-05-17T23:52:20Z","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":"359d2977e95b6a8d4fbc1a889df9a838e62856f1be22cf7b31584218c28796c4","cross_cats_sorted":["cs.CV","cs.LG"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.IR","submitted_at":"2019-03-01T11:43:31Z","title_canon_sha256":"57adacc4ca05dc47dc14b7b0163baa6ad5cca9561411c748142b17e21f28bb49"},"schema_version":"1.0","source":{"id":"1903.00252","kind":"arxiv","version":1}},"canonical_sha256":"1266a8bfc28b6fa0cde1c34e030bd5efa06f3ff155fe89107c72d09994441fd7","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"1266a8bfc28b6fa0cde1c34e030bd5efa06f3ff155fe89107c72d09994441fd7","first_computed_at":"2026-05-17T23:52:20.335009Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:52:20.335009Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"QKDhy1lcCj9BuSMFVKDC9nfZDBjB+z9qS3TzZBI7vgMBDUtq+oanCAayGtGQ7a1iY1bvXEFZgLF+w7X7BgFECA==","signature_status":"signed_v1","signed_at":"2026-05-17T23:52:20.335669Z","signed_message":"canonical_sha256_bytes"},"source_id":"1903.00252","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:626807fcb28cd06adef8e76ed44699b17f682cbfd41faf2fd447e0312a17c400","sha256:be7f6c4c15e9d9b09b7d4dc5ae613c5628d0a8c7c89ed6e4d43cb723627ae570"],"state_sha256":"e2e5bb028bd66a675b41ebb6b80f2fae0a8fb9522ef7f756f3e1c604e77ac016"}
