For the respiratory status task (stable vs. exacerbated), the AUC improves from 0.897 to 0.910. For the exacerbation type task (asthma exacerbation vs. COPD exacerbation), the AUC increases from 0.674 to 0.793. Concurrently, the J-ratio decreases, confirming effective suppression of speaker information. External validation on the Bridge2AI-Voice dataset further demonstrates consistent performance improvement and reduced speaker dependency.","weakest_assumption":"The assumption that gradient reversal-based adversarial training successfully isolates pathology-related acoustic patterns from speaker-identifiable attributes without degrading the primary classification performance, as the abstract states this occurs but provides no quantitative verification of feature separation quality or ablation studies."}},"verdict_id":"35643bbd-3e4c-46f2-8b76-53e1d616e47e"}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:e9b2bb759f0e9bbffb890e87a8521fb0ca2531895b9c2387999bcc5075fec6e2","target":"record","created_at":"2026-05-20T00:03:27Z","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":"21435a63ecb5a9bdf7a76be212a6d3f5501e5e52731d7d6366a0c24fe6f18ac3","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by-nc-nd/4.0/","primary_cat":"cs.SD","submitted_at":"2026-05-16T08:39:30Z","title_canon_sha256":"736229467af5942990e41fb8a8ce553f9160250c483a6ea8aeb94615c2895b7a"},"schema_version":"1.0","source":{"id":"2605.16878","kind":"arxiv","version":1}},"canonical_sha256":"f7bb432d7ea0a2dac89f11ccae108ed89c286599148e49299e342fc3992a7839","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"f7bb432d7ea0a2dac89f11ccae108ed89c286599148e49299e342fc3992a7839","first_computed_at":"2026-05-20T00:03:27.833660Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-20T00:03:27.833660Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"6ngT5bD0Ci4wfS0fR7PUVyca4mZYoHpd0BG9N+RcRfrhBpvKMwiTfM7kOGI6N4S4ZyOV4mhWS6SDefk8yLb+Bw==","signature_status":"signed_v1","signed_at":"2026-05-20T00:03:27.834556Z","signed_message":"canonical_sha256_bytes"},"source_id":"2605.16878","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:e9b2bb759f0e9bbffb890e87a8521fb0ca2531895b9c2387999bcc5075fec6e2","sha256:888a5eaa6763b2d184fc940f3e1865e6321c17a55c315bd7aafae1eb46bf3eff"],"state_sha256":"25ac7f1c9f0906a0325388be81a18dd623506a3725cb1593417ad8234de8dd11"},"bundle_signature":{"signature_status":"signed_v1","algorithm":"ed25519","key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signature_b64":"75cQX86zoAW/ll2i5SsbcTpTjBVUtmo2BHRI9cPA+MI0wGwUH1/5WjRMVzApjX00dE1nhFTOskHm3SOE3NHvDw==","signed_message":"bundle_sha256_bytes","signed_at":"2026-05-22T04:31:59.284565Z","bundle_sha256":"91545261a8bbe534c86cfe64da0f572bd6c00c33253dbf748f72bb41f13e4c79"}}
