An identifier of each database vector is associated with the slot of a hash table by using its PQ-code as a key. For querying, an input vector is PQ-encoded and hashed, and the items associated with that code are then retrieved. The proposed PQTable produces the same results as a linear PQ scan, and is 10^2 to 10^5 times faster. Although state-of-the-art performance can be achieved by previous inverted-indexing-based approaches, such methods require manually-desig","authors_text":"Kiyoharu Aizawa, Toshihiko Yamasaki, Yusuke Matsui","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2017-04-21T14:22:16Z","title":"PQTable: Non-exhaustive Fast Search for Product-quantized Codes using Hash Tables"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1704.06556","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:ca9781962c5e4833928e731b5e49f44b371c40c79ab9e452dc0f6e797a152815","target":"record","created_at":"2026-05-18T00:45:59Z","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":"2eb2c9ad07bf0174d426a8c906c2d38dfd299bec39e529e2116f19f7cb1dfeb7","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2017-04-21T14:22:16Z","title_canon_sha256":"9157e0c9379ce8358c561beb61bf2784f30510f48886fb3b05145745be757798"},"schema_version":"1.0","source":{"id":"1704.06556","kind":"arxiv","version":1}},"canonical_sha256":"b688c3ef2b00a54ab0055f77b77f0d05fc9a3631fdcfa7b6bfa11a3dc2396ce0","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"b688c3ef2b00a54ab0055f77b77f0d05fc9a3631fdcfa7b6bfa11a3dc2396ce0","first_computed_at":"2026-05-18T00:45:59.387215Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:45:59.387215Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"L8o+y7qcPGbxceEMGTq4YywvCw6qfR/TdGkq+1vMMdXjtHn/2MhICgTIakD+6Gtdh6XOPnMWf3SKID2wGKRqBQ==","signature_status":"signed_v1","signed_at":"2026-05-18T00:45:59.387647Z","signed_message":"canonical_sha256_bytes"},"source_id":"1704.06556","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:ca9781962c5e4833928e731b5e49f44b371c40c79ab9e452dc0f6e797a152815","sha256:b2c65e6ee79b6c5c29cd47d7efbd6b187edb1e5cf7a21777c1ba48dcd2690165"],"state_sha256":"62a224a764aadd7f10b365859a46b8bde692f4f18ac4e264a4fac0ea4d18b5f3"}
