This scenario raises the following questions: Without any labeled data and without any a-priori knowledge about the reliability of these different classifiers, is it possible to consistently and computationally efficiently estimate their accuracies? Furthermore, also in a completely unsupervised manner, can one construct a more accurate unsupervised ensemble classifier? In this paper, focusing on the binary case, we present simple, computationally efficient algorithms to solve thes","authors_text":"Ariel Jaffe, Boaz Nadler, Yuval Kluger","cross_cats":["cs.LG"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"stat.ML","submitted_at":"2014-07-29T07:19:08Z","title":"Estimating the Accuracies of Multiple Classifiers Without Labeled Data"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1407.7644","kind":"arxiv","version":2},"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:c8b96897532442eacdf7495076254874fc15f4462ea35fb1a06b1b3270585589","target":"record","created_at":"2026-05-18T02:39:00Z","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":"9e2f68b0bd6d81a7dc1548263bd13ee81facaf6c9728b62fd6ae6a10792c6cb1","cross_cats_sorted":["cs.LG"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"stat.ML","submitted_at":"2014-07-29T07:19:08Z","title_canon_sha256":"6f90ddbcd4189ad22260878e7ebc482962db5d97ee0ee09476444a128fe19b8c"},"schema_version":"1.0","source":{"id":"1407.7644","kind":"arxiv","version":2}},"canonical_sha256":"6de900379092be6e2dbdab6ffd6828df0325e63d6efb14cc37ea26c4f4451ce8","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"6de900379092be6e2dbdab6ffd6828df0325e63d6efb14cc37ea26c4f4451ce8","first_computed_at":"2026-05-18T02:39:00.768580Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:39:00.768580Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"508t2cgW64TD3OdeoRsSV+VzeGMgcQ+ssPr+lEILiIZftGHbZnumMCvrpKMg2mwos6OxK46TTykwntGlDwqwBg==","signature_status":"signed_v1","signed_at":"2026-05-18T02:39:00.769220Z","signed_message":"canonical_sha256_bytes"},"source_id":"1407.7644","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:c8b96897532442eacdf7495076254874fc15f4462ea35fb1a06b1b3270585589","sha256:14c55b12e3e65a0d513f659fcf4a9ac32e9c725157774c9756007f19562fd0e5"],"state_sha256":"ff3f148f9940df4f085ae9bc852afc995f1bd5361ca4e739789cd7e0288a5728"}
