Recent work of Tapia Costa et al. (2026) introduced a novel technique for estimating the drift when the diffusion parameter is known, using discrete samples from multiple trajectories. Their method treats drift estimation as a denoising problem, and leverages tools from (conditional) score-matching diffusion models. Although their experiments showed promising results across different drift classes, the question of theoretical guarantees for their estimator ","authors_text":"Ioar Casado-Telletxea, Omar Rivasplata","cross_cats":["cs.LG"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"stat.ML","submitted_at":"2026-06-01T11:47:34Z","title":"Error Bounds for a Diffusion Model-Based Drift Estimator"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2606.02115","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:b2397e41184eb4b92e83fee8ea04315cbbeba0a0886bac3d7a86f35803c1bb2e","target":"record","created_at":"2026-06-02T02:05:06Z","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":"6ee93fa0b4380d6e0eed71e4234bd67fcfb34fb3ba34d7ad945d524332c64e3c","cross_cats_sorted":["cs.LG"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"stat.ML","submitted_at":"2026-06-01T11:47:34Z","title_canon_sha256":"6f1d26a52dc39c1e046538188c61ca43ad6e6d298b4236e3a6ed81c8639bb91b"},"schema_version":"1.0","source":{"id":"2606.02115","kind":"arxiv","version":1}},"canonical_sha256":"837ce94022abc8faceef58fd4682fc9f8d417734f47f51bc3ba9ce770d538df8","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"837ce94022abc8faceef58fd4682fc9f8d417734f47f51bc3ba9ce770d538df8","first_computed_at":"2026-06-02T02:05:06.842974Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-06-02T02:05:06.842974Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"ZGnHO27oguPPKaBNzaYW8cfl1YgKAwstwfmtAGPHgp/7tdZZEPkBFltfp4qwnpdF7qRmRpg8k5L776IOE8bADQ==","signature_status":"signed_v1","signed_at":"2026-06-02T02:05:06.843384Z","signed_message":"canonical_sha256_bytes"},"source_id":"2606.02115","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:b2397e41184eb4b92e83fee8ea04315cbbeba0a0886bac3d7a86f35803c1bb2e","sha256:dc8becb6d542d7888e742416bedd8a892a6e79def9e97b229587f5a06bb4441c"],"state_sha256":"99231cdd12f285173812fbe900fe4cb7bdda8e813c7cc5d66c97f208c9b7b6c9"}
