Since EMG system parameters, such as the feature extraction methods and the number of channels, have been known to affect system performances, it is important to investigate these effects on the performance of the sEMG-based biometric system to determine optimal system parameters. In this study, three robust feature extraction methods, Time-domain (TD) feature, Frequency Division Technique (FDT), and Autoregressive (AR) feature, and their combinations were investigated while the number of channels var","authors_text":"Ashirbad Pradhan, Jiayuan He, Ning Jiang","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by-nc-sa/4.0/","primary_cat":"eess.SP","submitted_at":"2021-03-10T12:24:55Z","title":"Performance Optimization of Surface Electromyography (sEMG) based Biometric Sensing System for both Verification and Identification"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2103.06015","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":"sha256:15ce2eb174eac2c034d255a7b6a764b284c0c5285d7b8c18cb94075fd0e8591b","target":"record","created_at":"2026-07-05T02:22:00Z","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":"4fc96d0f0b4137af177510b1c5a461f93e1fd37b7a5b7207ad79c50946054fd6","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by-nc-sa/4.0/","primary_cat":"eess.SP","submitted_at":"2021-03-10T12:24:55Z","title_canon_sha256":"58c69daef0fd610f69940f206cb6c42cb968233c9e0e4b78808d324205e1a8bc"},"schema_version":"1.0","source":{"id":"2103.06015","kind":"arxiv","version":1}},"canonical_sha256":"56f2dc2ed3293606dfd150654e107a3ebc15990f4a7951ff16dd6a2bb710b86d","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"56f2dc2ed3293606dfd150654e107a3ebc15990f4a7951ff16dd6a2bb710b86d","first_computed_at":"2026-07-05T02:22:00.696813Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T02:22:00.696813Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"v2fOdPDRaU1ckEaf2PcQe0yTJP1hi82vrreUw5bKNtFazCLHZiFqHLSDOwDrrQH55pJG+j3z4HoTaWIlrZzhBg==","signature_status":"signed_v1","signed_at":"2026-07-05T02:22:00.697195Z","signed_message":"canonical_sha256_bytes"},"source_id":"2103.06015","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:15ce2eb174eac2c034d255a7b6a764b284c0c5285d7b8c18cb94075fd0e8591b","sha256:2cfe88fd6e1bb09e9cda0de72fd09b70597fee790e3aa4ae05e0afc7a50ace69"],"state_sha256":"fa7f3072baa4435b9f06febe10c33c322f72f1faf6d4faa3f88da26edfab4eee"}
