One of the most sensitive hyperparameters is the learning rate of the gradient descent. We present the 'All Learning Rates At Once' (Alrao) optimization method for neural networks: each unit or feature in the network gets its own learning rate sampled from a random distribution spanning several orders of magnitude. This comes at practically no computational cost. Perhaps surprisingly, stochastic gradient descent (SGD) with Alrao performs close to SGD with an optimally tuned learning rate, for various architectu","authors_text":"L\\'eonard Blier, Pierre Wolinski, Yann Ollivier","cross_cats":["cs.NE","stat.ML"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.LG","submitted_at":"2018-10-02T15:21:07Z","title":"Learning with Random Learning Rates"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1810.01322","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":"sha256:416f291e681eb9eb0f1b6a18542053012b807f214bac072ac5ced62da1b8841c","target":"record","created_at":"2026-05-17T23:55:19Z","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":"aaae59f50b7dba341274008d4c2efbcd499aafd53d8a2f7e119c694c3823124f","cross_cats_sorted":["cs.NE","stat.ML"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.LG","submitted_at":"2018-10-02T15:21:07Z","title_canon_sha256":"a56922364608d29acb75a3204c472bb20f3902cd01ef13da17ed32b889a44bbc"},"schema_version":"1.0","source":{"id":"1810.01322","kind":"arxiv","version":3}},"canonical_sha256":"11112576017b60d070200fc31c2757dcf786322b4a2ef5a6983a1b309404ab78","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"11112576017b60d070200fc31c2757dcf786322b4a2ef5a6983a1b309404ab78","first_computed_at":"2026-05-17T23:55:19.609142Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:55:19.609142Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"4qP+zC/uKXe0wkmyFii+tJ9ruYHN1RMMeFS7QawDc3snww3KIxCWg+o2J7TsJC2J23Mu+dIHSWSjO7yobgpVAQ==","signature_status":"signed_v1","signed_at":"2026-05-17T23:55:19.609575Z","signed_message":"canonical_sha256_bytes"},"source_id":"1810.01322","source_kind":"arxiv","source_version":3}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:416f291e681eb9eb0f1b6a18542053012b807f214bac072ac5ced62da1b8841c","sha256:5e88bd01cb7f97b5c2c5670f18963c1e89a08d31d78f66153ba17acede7f994e"],"state_sha256":"85a1c5b8aba6bafe8b44fd8e5385b97817eeaecb77251f550d19713291628637"}
