The interpretation of EIS is the biggest challenge in this technology, which requires reasonable modeling. However, the modeling of EIS is of great subjectivity, meaning that there may be several models to fit the same set of data. In order to overcome the uncertainty and triviality of human analysis, this research uses machine learning to carry out EIS pattern recognition. Raw EIS data and their equivalent circuit models were collected from the literature, and the support vector machi","authors_text":"Junwei Sha, Naiqin Zhao, Shan Zhu, Xinyang Sun, Yuxuan Wang","cross_cats":["physics.app-ph","physics.comp-ph"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.data-an","submitted_at":"2019-07-03T09:05:27Z","title":"Equivalent Circuit Model Recognition of Electrochemical Impedance Spectroscopy via Machine Learning"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1907.01802","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":"sha256:21f9b9907bd6df7bfce238f2c45dfa4684122e44c4a421a92fc5b79724da6ba9","target":"record","created_at":"2026-05-17T23:41:35Z","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":"66b69bb580a62e726c62f685b832170ecaf7a321251797582fb35cec37ea74f5","cross_cats_sorted":["physics.app-ph","physics.comp-ph"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.data-an","submitted_at":"2019-07-03T09:05:27Z","title_canon_sha256":"41ae0d5d9357281713233bd43ac6ea3307c9b921c276b78408ae6b8ed64a749c"},"schema_version":"1.0","source":{"id":"1907.01802","kind":"arxiv","version":1}},"canonical_sha256":"93a63d391c2d5b8760fd1782e5c6761ef6deb3c2973ca4ebd6c91416b7a898b8","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"93a63d391c2d5b8760fd1782e5c6761ef6deb3c2973ca4ebd6c91416b7a898b8","first_computed_at":"2026-05-17T23:41:35.002228Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:41:35.002228Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"roeBGIZ6sboBtoi/0ASuJ+bzfq0UPaSizlG69pCprA8e83/hLj5spHkrm0ew2W0r+I4Tha/liJPIGZczPGn7DQ==","signature_status":"signed_v1","signed_at":"2026-05-17T23:41:35.002777Z","signed_message":"canonical_sha256_bytes"},"source_id":"1907.01802","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:21f9b9907bd6df7bfce238f2c45dfa4684122e44c4a421a92fc5b79724da6ba9","sha256:d7eb2e5c75e54cfabe0d634227825bf841f88a26b5221acc13eb6d2638b8fd5f"],"state_sha256":"49988adf7544622c7f6424d9d7d4590c10af9125a6a84149207d34cbec501fcc"}
