Here we propose a statistical machine-learning approach to derive lowdimensional models that automatically integrate information in noisy time-series data from partial observations. The method is tested using artificial data generated from two cell-cycle control system models that exhibit different bifurcations, and the learned systems are shown to robustly inherit the bifurcation structure.","authors_text":"Kunihiko Kaneko, Shuji Ishihara, Yohei Kondo","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"q-bio.QM","submitted_at":"2012-08-23T02:41:36Z","title":"Identifying dynamical systems with bifurcations from noisy partial observation"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1208.4660","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":"sha256:720b8520770f1766656158c23cb09b5e236af244598d13939c7c6fa1765db287","target":"record","created_at":"2026-05-18T01:54:59Z","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":"896b60130cefc63d0957ae3825a42ca5a555fb27dbdd4bbd4687f91a53cbfef7","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"q-bio.QM","submitted_at":"2012-08-23T02:41:36Z","title_canon_sha256":"617d6837930be4f25c753af681a01245e9bc8e3536951d6447a51def8b096525"},"schema_version":"1.0","source":{"id":"1208.4660","kind":"arxiv","version":1}},"canonical_sha256":"0ff1793931c65a364cc06c12af2dbcef04b3c8711a4964235ef20aef1d0ecc67","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"0ff1793931c65a364cc06c12af2dbcef04b3c8711a4964235ef20aef1d0ecc67","first_computed_at":"2026-05-18T01:54:59.253781Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:54:59.253781Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"RoYQY9doonSKjC193jOArkju7Ejg/gLPYrBDIemh6Gk/I4z684boBwdwjEiCPVlJUfPnGSBejzaOg2BrqHKKAg==","signature_status":"signed_v1","signed_at":"2026-05-18T01:54:59.254376Z","signed_message":"canonical_sha256_bytes"},"source_id":"1208.4660","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:720b8520770f1766656158c23cb09b5e236af244598d13939c7c6fa1765db287","sha256:b0804da26b1e306a1e4b48ab9b5d5c27f61a01040e6cd7e01d4cc6839551d831"],"state_sha256":"10dfa47add6e4bdb99a69870b4f949fc9ee3cb4c5fa70b24a0cde4cae0ee6dba"}
