To relieve this issue and consistently improve the model training speed across deep networks, we propose the ADAptive Nesterov momentum algorithm, Adan for short. Adan first reformulates the vanilla Nesterov acceleration to develop a new Nesterov momentum estimation (NME) method, which avoids the extra overhead of computing gradient at the extrapolation point. Then, Adan adopts NME to estimate the gradient's first- and s","authors_text":"Huan Li, Pan Zhou, Shuicheng Yan, Xingyu Xie, Zhouchen Lin","cross_cats":["math.OC"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.LG","submitted_at":"2022-08-13T16:04:39Z","title":"Adan: Adaptive Nesterov Momentum Algorithm for Faster Optimizing Deep Models"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2208.06677","kind":"arxiv","version":5},"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":"sha256:5e443ef649d15f9c37c781ef2f6ac2118fa0dc1b0beea3546e8fd4f4c1b6f579","target":"record","created_at":"2026-07-05T09:41:26Z","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":"fa1eec7a19a75346b3a671caeed12b838e6c8bbc78d072488c82fb52726441f8","cross_cats_sorted":["math.OC"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.LG","submitted_at":"2022-08-13T16:04:39Z","title_canon_sha256":"bacf8eefa35b6d80fc84b172cf3cfdceeb6d3e4f1da15bad82f29427151bf795"},"schema_version":"1.0","source":{"id":"2208.06677","kind":"arxiv","version":5}},"canonical_sha256":"130b0f50375cb8a16702cb85c02e14e78655ac29270c367064f3781007392fcd","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"130b0f50375cb8a16702cb85c02e14e78655ac29270c367064f3781007392fcd","first_computed_at":"2026-07-05T09:41:26.245810Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T09:41:26.245810Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"LRwCYO/HVuorUZ4KlIFP0vJcY01J3pEE5v52gMKwqJmWdiewUFuFsszGWU4ABWyW1LdUG6NJwRW91ghemeqfAQ==","signature_status":"signed_v1","signed_at":"2026-07-05T09:41:26.246369Z","signed_message":"canonical_sha256_bytes"},"source_id":"2208.06677","source_kind":"arxiv","source_version":5}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:5e443ef649d15f9c37c781ef2f6ac2118fa0dc1b0beea3546e8fd4f4c1b6f579","sha256:78f2b8763a030c8a77cb0016dfd0c724f5dc23b72f64633334861917bcb7e654"],"state_sha256":"0460ad92b1bf0b95593363ab35d1d1970239524b7c58240d121308c356e5d7d4"}
