We propose a model-free RL method that modifies Delayed Q-learning and utilizes the long-term exploration bonus with provable efficiency. We show that our proposed method finds a near-optimal policy in polynomial time (PAC-MDP), and also provide experimental evidence that our proposed algorithm is an efficient exploration method.","authors_text":"Garud Iyengar, Min-hwan Oh","cross_cats":["stat.ML"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.LG","submitted_at":"2018-08-31T00:00:22Z","title":"Directed Exploration in PAC Model-Free Reinforcement Learning"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1808.10552","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":"sha256:2d473cb6fb81c9d20965eb7d9fe9efc257f0aa7fe4dc72ae3f2ad25bea9d76db","target":"record","created_at":"2026-05-18T00:06:45Z","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":"72b5d45c5a668f71ea974e0871f5e9e359789cf34e776f5bb6fa5331e1f91ee9","cross_cats_sorted":["stat.ML"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.LG","submitted_at":"2018-08-31T00:00:22Z","title_canon_sha256":"5957c1c8a82305733788140287136d9838ea0c56c467d702c6ffd2ecaf9b7129"},"schema_version":"1.0","source":{"id":"1808.10552","kind":"arxiv","version":1}},"canonical_sha256":"c76a443824c193f6ce1a241ac66aec12606021d2e9ac74ed3429e0daeceec02d","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"c76a443824c193f6ce1a241ac66aec12606021d2e9ac74ed3429e0daeceec02d","first_computed_at":"2026-05-18T00:06:45.386660Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:06:45.386660Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"fVFN2SEjty0X3gSGw4Cv23kSnj2pkPu8/3X2wZdvAN9fz5jn9GoWzqEhjYK6CWFdLtCoB/hw9DA9x2IqIEDFDQ==","signature_status":"signed_v1","signed_at":"2026-05-18T00:06:45.387286Z","signed_message":"canonical_sha256_bytes"},"source_id":"1808.10552","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:2d473cb6fb81c9d20965eb7d9fe9efc257f0aa7fe4dc72ae3f2ad25bea9d76db","sha256:2700bbee5648c676e001148492406458befb7824f596cb199c652b51b8f76e25"],"state_sha256":"06fa642f770df13f2da5b52b5a6e95c79c66cc67421cde083ade60fafe616674"}
