Previous work in this area has concentrated on the case when the learner is restricted to deterministic classifiers. In contrast, we perform a theoretical analysis of an extension to this setting that allows the learner to produce a randomised classifier. We show that, under certain conditions, the optimal randomised classifier can achieve better accuracy than the optimal deterministic classifier, but under no conditions can it be w","authors_text":"Henry Gouk, Jack Geary","cross_cats":["stat.ML"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.LG","submitted_at":"2025-02-03T12:41:55Z","title":"Strategic Classification with Randomised Classifiers"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2502.01313","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":"sha256:599ff4cfc018907348df5549cc48d1a7dd565fef8f69104eacd2dbcb294dc247","target":"record","created_at":"2026-07-05T11:03:56Z","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":"301e8fe254b36f4ee0fe9be2e74b2dadfa525bf37471edcae96e7e7e92328a4c","cross_cats_sorted":["stat.ML"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.LG","submitted_at":"2025-02-03T12:41:55Z","title_canon_sha256":"ae09964328b07e086a053e7d4b5bba028e65ba31c3783bf0376ec2abdccd2ef4"},"schema_version":"1.0","source":{"id":"2502.01313","kind":"arxiv","version":2}},"canonical_sha256":"df8b8e02d4518e9a57a82169e9ee5b5afdc94c6901232104ea7aac31f6ab01a7","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"df8b8e02d4518e9a57a82169e9ee5b5afdc94c6901232104ea7aac31f6ab01a7","first_computed_at":"2026-07-05T11:03:56.095537Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T11:03:56.095537Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"4jA8tWd7VN8GIr4bgUSdJR7pSMHgOwEGXTCRukeKGbk5byAIzs4xNTFCMowcglUVpwl/0OqJ+skRomTegZ27DA==","signature_status":"signed_v1","signed_at":"2026-07-05T11:03:56.096085Z","signed_message":"canonical_sha256_bytes"},"source_id":"2502.01313","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:599ff4cfc018907348df5549cc48d1a7dd565fef8f69104eacd2dbcb294dc247","sha256:330b0574b83c3a8ad1474f0dfaecfc378f942046a3d2c1d27e97b77ab28f78fd"],"state_sha256":"9939ee03070b51ffba951e923d974c08d5bad329b8c53e8d92ed47d29592f376"}
