However, the leaky DLMS algorithm may suffer from performance deterioration in the sparse system. To overcome this drawback, the leaky zero attracting DLMS (LZA-DLMS) algorithm is developed in this paper, which adds an l1-norm penalty to the cost function to exploit the property of sparse system. The leaky reweighted zero attracting DLMS (LRZA-DLMS) algorithm is also put forward, which can improve the ","authors_text":"Haiquan Zhao, Long Shi","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"eess.SP","submitted_at":"2018-01-05T11:22:44Z","title":"Diffusion Leaky Zero Attracting Least Mean Square Algorithm and Its Performance Analysis"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1801.01717","kind":"arxiv","version":2},"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":"sha256:9ce65afe6f1ff6ced5844863c148f0c2689ee33df00d35f6194137f7d05940f3","target":"record","created_at":"2026-05-18T00:01:53Z","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":"5cdb813266a16f0c220f44035c8eeb1742e1affd903a0e625d2e5a58957a6f74","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"eess.SP","submitted_at":"2018-01-05T11:22:44Z","title_canon_sha256":"e8022bbeda56c253f980492ace9865cabc96ddf3cc26c970d662c958156b0a9d"},"schema_version":"1.0","source":{"id":"1801.01717","kind":"arxiv","version":2}},"canonical_sha256":"2ada71a82e6aee9e95c66002bc10ac7a1f6e9322d4c3661457c61c2c12b0f4ec","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"2ada71a82e6aee9e95c66002bc10ac7a1f6e9322d4c3661457c61c2c12b0f4ec","first_computed_at":"2026-05-18T00:01:53.497351Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:01:53.497351Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"IfJ31lCzYtdrbIXhE7ZN1Kcx9+wvDZHIOSGISRWXnrOhMFPGE2dUu8EjiIihAi9xEli/CvSallTedo51MFrUBA==","signature_status":"signed_v1","signed_at":"2026-05-18T00:01:53.497756Z","signed_message":"canonical_sha256_bytes"},"source_id":"1801.01717","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:9ce65afe6f1ff6ced5844863c148f0c2689ee33df00d35f6194137f7d05940f3","sha256:715b5a1bd9205370cdaf308942a69b255cce1a51d0f6edad76e9579fc538a5b8"],"state_sha256":"080e928291208753820e7f5155a5e4d0eca2e9c27dec2fce2fd719f5c9973f09"}
