Our method learns to minimize the cost of transporting a predicted distribution of note events to the ground-truth distribution over time and frequency. The OT loss can thus accommodate temporal misalignment, leading to perceptually relevant optimization.","weakest_assumption":"That minimizing optimal transport cost between predicted and ground-truth note distributions produces perceptually superior transcriptions and that a harmonics-aware attention mechanism in the CRNN sufficiently captures the necessary spectro-temporal dependencies in piano signals."}},"verdict_id":"0ad74f8e-023e-4f80-85fe-a048e5acf83c"}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:f32e1bf5c6562c20f5d9bccddd7d779fa6c7ee2260585864b16f9c9cf368b0f7","target":"record","created_at":"2026-05-20T00:03:56Z","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":"2db5573339328817fa5db9d2ad28b4d5de1c29c0bd62ba2de2ac333cf9bad8a7","cross_cats_sorted":["cs.MM"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.SD","submitted_at":"2026-05-17T12:01:44Z","title_canon_sha256":"d9359b07a5d1c4f081469e2c2141444dcd67a9adcf8a0e823f42dd16fef707b5"},"schema_version":"1.0","source":{"id":"2605.17405","kind":"arxiv","version":1}},"canonical_sha256":"2b3693044f8e0653abb1be31215642fb7879cee28a835f87bda684bb54054b8d","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"2b3693044f8e0653abb1be31215642fb7879cee28a835f87bda684bb54054b8d","first_computed_at":"2026-05-20T00:03:56.794282Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-20T00:03:56.794282Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"uXROsRyaSNDK9R+5uDBOFWJAfP8O3icd5l1Ng243Kb2mT0ssbtSVKkcG/jBEDc4eXrZZoCEy26EMAcL5aADtBA==","signature_status":"signed_v1","signed_at":"2026-05-20T00:03:56.794937Z","signed_message":"canonical_sha256_bytes"},"source_id":"2605.17405","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:f32e1bf5c6562c20f5d9bccddd7d779fa6c7ee2260585864b16f9c9cf368b0f7","sha256:2609d1b770031471b8974848dd7417e6a7c33782e073c4a603cf26cc8fad1ccc"],"state_sha256":"2008949aa8f1082ff5dc1398e3688b23cf83d143671c7e2d05ca2ab25ce07062"},"bundle_signature":{"signature_status":"signed_v1","algorithm":"ed25519","key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signature_b64":"4llcwmB2XA/boNB7UQLfUJB05gS6UkLKQA0uVQO7VYrhM4n/ZAn5wXJ6SV5tyHPIM/kWlo+cLAYka7AbnRaOCQ==","signed_message":"bundle_sha256_bytes","signed_at":"2026-05-31T18:07:33.416753Z","bundle_sha256":"71372be1831dff95ea307f37be8377b5823d35127c1d4d6186920f21a1f2c2e2"}}
