The question addressed in this paper is: how can agents improve upon their locally trained model by communicating with other agents that have similar objectives? We introduce and analyze two asynchronous gossip algorithms running in a fully decentralized manner. Our first approach, inspired from label propagation, aims to smooth pre-trained local models over the network while accounting for the confidence that each agent has in its ","authors_text":"Aur\\'elien Bellet, Marc Tommasi, Paul Vanhaesebrouck","cross_cats":["cs.AI","cs.DC","cs.SY","stat.ML"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.LG","submitted_at":"2016-10-17T16:51:49Z","title":"Decentralized Collaborative Learning of Personalized Models over Networks"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1610.05202","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:e4ad51e16ca3615fb5b67c6162539d0706d30cc7418642d87391af58f0950665","target":"record","created_at":"2026-05-17T23:55:39Z","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":"1d810abe511310710d6dc59d4f1dc17437ad67ba399dc03cea2b05abb6be5b96","cross_cats_sorted":["cs.AI","cs.DC","cs.SY","stat.ML"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.LG","submitted_at":"2016-10-17T16:51:49Z","title_canon_sha256":"8c9958e0732b20909807267fcb3670efe1c3972fe7ed831c0fb450fd14a26dc7"},"schema_version":"1.0","source":{"id":"1610.05202","kind":"arxiv","version":2}},"canonical_sha256":"4d4ad44b187d021ea794ba650b4e08e53addff08b7ef69ecc8675b31d43bcba2","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"4d4ad44b187d021ea794ba650b4e08e53addff08b7ef69ecc8675b31d43bcba2","first_computed_at":"2026-05-17T23:55:39.087606Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:55:39.087606Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"7rgmPeLZTkgWjhwPxk4y3Pz8YRIVJe6+92MVZVKSIySDf/RZ7ijGGwsJ1GS6F5AADN7+rKIa5vc3NFPWiOluCg==","signature_status":"signed_v1","signed_at":"2026-05-17T23:55:39.088115Z","signed_message":"canonical_sha256_bytes"},"source_id":"1610.05202","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:e4ad51e16ca3615fb5b67c6162539d0706d30cc7418642d87391af58f0950665","sha256:6af47cbe5ff0570d0baec11b120550c2a54ea9e80c1fd7a58d6094c6fce101be"],"state_sha256":"ccd35a2455be3663f488add88019db9db0bd58145293fffd4d8000583cb6ddad"}
