We separate the problem and show that the method of multipliers can be applied to obtain a solution efficiently and in a decentralized fashion, i.e. all local estimators can compute their filter gains locally and iteratively, with communications restricted to their neighbours. The convergence properties of the iterative algorithm are analyzed and interpreted.","authors_text":"Frank Allg\\\"ower, Jingbo Wu, Li Li, Valery Ugrinovskii","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.SY","submitted_at":"2015-09-20T04:47:57Z","title":"Distributed Filter Design for Cooperative H-Infinity-Type Estimation"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1509.05967","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":"sha256:93c0e10d71c0b096471e3c8a2a83244e5ae00db64ab9c29250e52722da691313","target":"record","created_at":"2026-05-18T01:25:11Z","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":"5d6ce2d4df312ce765b9c9848bd28469924deb97e7259c17141ee25a0bee5cfa","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.SY","submitted_at":"2015-09-20T04:47:57Z","title_canon_sha256":"665b7ffb942758a8ab21ac6ae24295cdcc1e91fb6d9a85ded9f485146c2f816b"},"schema_version":"1.0","source":{"id":"1509.05967","kind":"arxiv","version":1}},"canonical_sha256":"25cfc148b05dbe4d696f2cfd91577b8c35f7657ba59bf8bc800e7ead4d18a9ab","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"25cfc148b05dbe4d696f2cfd91577b8c35f7657ba59bf8bc800e7ead4d18a9ab","first_computed_at":"2026-05-18T01:25:11.311083Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:25:11.311083Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"QGXSx+YLKvMET/12f6CwAt4eJmcTYEidp/XAP1DYHv1s1+mlB9oD8+oosyobZg4zUuFp9WrLe6z+0FxJb3BnBA==","signature_status":"signed_v1","signed_at":"2026-05-18T01:25:11.311765Z","signed_message":"canonical_sha256_bytes"},"source_id":"1509.05967","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:93c0e10d71c0b096471e3c8a2a83244e5ae00db64ab9c29250e52722da691313","sha256:e5d44076e6ed201fcd0416b270d0f85bbcf5dc46d4c8ac8982520e5680f702de"],"state_sha256":"5de3ad8a740423e02ae56168ba19b3289b7228ff80991254b8df6fcb38d267d9"}
