GAI is a pure-exploration problem that a single agent repeats a process of outputting an arm as soon as it is identified as a good one before confirming the other arms are actually not good. The objective of GAI is to minimize the number of samples for each process. We find that GAI faces a new kind of dilemma, the {\\em exploration-exploitation dilemma of confidence}, which is different diffi","authors_text":"Atsuyoshi Nakamura, Hideaki Kano, Junya Honda, Kentaro Matsuura, Kentaro Sakamaki, Masashi Sugiyama","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"stat.ML","submitted_at":"2017-10-17T16:08:16Z","title":"Good Arm Identification via Bandit Feedback"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1710.06360","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:afdd9090bd88978bc721ef25114c420f0bb914726cc363862cf3008bc5e131dd","target":"record","created_at":"2026-05-18T00:23:52Z","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":"ed5a469490074385a813c59857546b918a2dad967d1bd4421873d446fe77501a","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"stat.ML","submitted_at":"2017-10-17T16:08:16Z","title_canon_sha256":"daa91c3d20ee9d8d7c2e6dffc1920eba306862a09ddf8f06e9ef49829c583fd4"},"schema_version":"1.0","source":{"id":"1710.06360","kind":"arxiv","version":2}},"canonical_sha256":"a855c43323cf53802ef67df897f604e4ebf8b704cf8c3856e8838757c799fc80","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"a855c43323cf53802ef67df897f604e4ebf8b704cf8c3856e8838757c799fc80","first_computed_at":"2026-05-18T00:23:52.795925Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:23:52.795925Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"BL6R7cXFFkmvffiUKXZbCtzeX+uowqMCAJeylEB805EWRU3O6XhA01bg6RHv9022Tq42hHYATfQMAYBOeFYXAA==","signature_status":"signed_v1","signed_at":"2026-05-18T00:23:52.796661Z","signed_message":"canonical_sha256_bytes"},"source_id":"1710.06360","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:afdd9090bd88978bc721ef25114c420f0bb914726cc363862cf3008bc5e131dd","sha256:b3b9835674d1504f1954dbdcb20fedea8062a05b0d1a7a4b7f4616b7b2d54613"],"state_sha256":"583d742389d5421a29b6484f3a84684714bb7fec306a084e35452c937e7bb323"}
