A central aspect of them is their direct distributed implementation. However, the filtering performance is often traded with distributed communication and computational savings. To improve this tradeoff, this work generalizes state-of-the-art distributed graph filters to filters where every node weights the signal of its neighbors with different values while keeping the aggregation operation linear. This new implementation, labeled as edge-variant graph filter, yields a significant reduction in terms of communication rounds wh","authors_text":"Elvin Isufi, Geert Leus, Mario Coutino","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"eess.SP","submitted_at":"2018-08-09T03:01:44Z","title":"Advances in Distributed Graph Filtering"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1808.03004","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":"sha256:04d72abbbd3777a72850bc96d298246af89e28a04e6ec95c5a9e5bd3e46a82d6","target":"record","created_at":"2026-05-17T23:47:20Z","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":"c8fba066f8d3247b13885325770c1cfa8f922b53d1f5e9b3b2f019167eda71e6","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"eess.SP","submitted_at":"2018-08-09T03:01:44Z","title_canon_sha256":"eb4f39cf4ebb17d59f4779a46c9f8b62eaf92f07a8611c00fb835c2d8fa47e92"},"schema_version":"1.0","source":{"id":"1808.03004","kind":"arxiv","version":1}},"canonical_sha256":"3139e53b864a4ab7677c51d8c076867f9eb468483b21598e0396bbfd59d597b8","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"3139e53b864a4ab7677c51d8c076867f9eb468483b21598e0396bbfd59d597b8","first_computed_at":"2026-05-17T23:47:20.667520Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:47:20.667520Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"g8WdH+SrsYu9Tdg4/2HsiFuma7mJtqhiQJ0P/vnIjJg8eYTB0yqbapkErG2C2u08ocaN0f4VANAQvaCB+9BIDw==","signature_status":"signed_v1","signed_at":"2026-05-17T23:47:20.667991Z","signed_message":"canonical_sha256_bytes"},"source_id":"1808.03004","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:04d72abbbd3777a72850bc96d298246af89e28a04e6ec95c5a9e5bd3e46a82d6","sha256:b3ed7f1226cd29dcf87320a5c54c991f86e8398e8c07889b1111083317ee75b1"],"state_sha256":"c9754226c78f8d1632a97a023542291c4e520c00fbc97b4b44d9dbc0049ea6a9"}
