Among the main algorithm families, sparse norm constraint adaptive filters develop rapidly in recent years. However, when applied for system identification, most priori work in sparse norm constraint adaptive filtering suffers from the difficulty of adaptability to the sparsity of the systems to be identified. To address this problem, we propose a novel variable p-norm constraint least mean square (LMS) algorithm, which serves as a variant of the conventional Lp-LMS algorithm es","authors_text":"Fei Chen, Huazhong Shu, Jiasong Wu, Rui Zeng, Yong Feng","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.SY","submitted_at":"2015-09-26T09:01:56Z","title":"Error Gradient-based Variable-Lp Norm Constraint LMS Algorithm for Sparse System Identification"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1509.07951","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:a41a2d5f3c53960cfd6ac9c2d636317949638bf9a4b15a314223f1d185501ebe","target":"record","created_at":"2026-05-18T01:31:55Z","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":"b18814b1c54d72bfa8d3bc6f01b3a613e8581b81d3311b660c138b6da6c49595","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.SY","submitted_at":"2015-09-26T09:01:56Z","title_canon_sha256":"ca3b22ffdaacfcab846d692fc4ea97a75e19a0ad2caaa7d5c58331d8e0e98571"},"schema_version":"1.0","source":{"id":"1509.07951","kind":"arxiv","version":1}},"canonical_sha256":"b81f899084cd800dfaae558cef7cb4e7ddc28a2cc98c79fcc34a768eec3a18dc","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"b81f899084cd800dfaae558cef7cb4e7ddc28a2cc98c79fcc34a768eec3a18dc","first_computed_at":"2026-05-18T01:31:55.052963Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:31:55.052963Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"qi79m3Dh94MFHriDqC45Xe1LYk4aX3NmT5ADbcqF+GuM5VzxEZCcPbKimzqIax1t/exnHxB7HK3BgWS/tLakCg==","signature_status":"signed_v1","signed_at":"2026-05-18T01:31:55.053352Z","signed_message":"canonical_sha256_bytes"},"source_id":"1509.07951","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:a41a2d5f3c53960cfd6ac9c2d636317949638bf9a4b15a314223f1d185501ebe","sha256:324193309cb8a82d38c08e066f26a7dded55fa40fb2cc09cee4db23397e26862"],"state_sha256":"f6bef700d866048001976a131d5da2aeaa6bb656a0819581825c87400c8d630b"}
