Namely, we show that the benefits of target labels are controlled by a transfer-exponent $\\gamma$ that encodes how singular Q is locally w.r.t. P, and interestingly allows situations where transfer did not seem possible under previous insights. In fact, our new minimax analysis - in terms of $\\gamma$ - reveals a continuum of regimes ranging from situations where target labels have little benefit, to regimes where target labels dramatically improve classification","authors_text":"Guillaume Martinet, Samory Kpotufe","cross_cats":["cs.LG"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"stat.ML","submitted_at":"2018-03-05T18:52:08Z","title":"Marginal Singularity, and the Benefits of Labels in Covariate-Shift"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1803.01833","kind":"arxiv","version":3},"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":"sha256:5bfda7d55005a4ff3abb0d348ddd5893f25a30204270753b98d41f0cbb789492","target":"record","created_at":"2026-07-05T01:10:23Z","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":"3dff89c39d161eb153af6b871ad967a6fff7b9d4b9c2d22179b4128e8a37c432","cross_cats_sorted":["cs.LG"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"stat.ML","submitted_at":"2018-03-05T18:52:08Z","title_canon_sha256":"79aea2b5998201ba10a3bf5bb5d147949bb96bd91d7a4703f1a26667387a306b"},"schema_version":"1.0","source":{"id":"1803.01833","kind":"arxiv","version":3}},"canonical_sha256":"1b154097fa5cfd8e7f0f955a8cc9c363e9ef92da49f68bc5bfea32564e323375","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"1b154097fa5cfd8e7f0f955a8cc9c363e9ef92da49f68bc5bfea32564e323375","first_computed_at":"2026-07-05T01:10:23.621399Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T01:10:23.621399Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"WhbAA8MeOQ6EKn2wrCDiwa3rn0ntidoGp3PFF6cdNsDlBRFsF6G5e3YdiKZKm1Y76T+wWMMo3cQDgkVQR/OtAg==","signature_status":"signed_v1","signed_at":"2026-07-05T01:10:23.621882Z","signed_message":"canonical_sha256_bytes"},"source_id":"1803.01833","source_kind":"arxiv","source_version":3}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:5bfda7d55005a4ff3abb0d348ddd5893f25a30204270753b98d41f0cbb789492","sha256:972ee6ac1e0d7c369f19767da89cbeb24a3d030e3381087650e4c4277d87856f"],"state_sha256":"3171ce1c1ed6af0dc722d006ea869e5b4eca6e5aeecea718be5978c3ed99a042"}
