Existing federated learning mostly adopts the central server-based architecture or centralized architecture. However, in many social network scenarios, centralized federated learning is not applicable (e.g., a central agent or server connecting all users may not exist, or the communication cost to the central server is not affordable). In this paper, we consider a generic setting: 1) the central server may not exist, and 2) the social network is unidirectional or o","authors_text":"Chaoyang He, Conghui Tan, Hanlin Tang, Ji Liu, Shuang Qiu","cross_cats":["cs.SI","stat.ML"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.LG","submitted_at":"2019-10-11T03:36:53Z","title":"Central Server Free Federated Learning over Single-sided Trust Social Networks"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1910.04956","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:add42de2c875c31b15972864616643bd86f0153f3c1930ce7a8d491e428238f4","target":"record","created_at":"2026-07-05T01:23:55Z","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":"ca9dd0d7a99dd46235de52a4f6a721902bd546da21224272e1dde612aace576f","cross_cats_sorted":["cs.SI","stat.ML"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.LG","submitted_at":"2019-10-11T03:36:53Z","title_canon_sha256":"9f97c2706f8a4f47b959315e2760d75813692f4a0daee92a2c7a118a0d9bb484"},"schema_version":"1.0","source":{"id":"1910.04956","kind":"arxiv","version":2}},"canonical_sha256":"b84b0b9520b722f7b49e7dcaf373a0a748536b960b163c16583169358dad5396","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"b84b0b9520b722f7b49e7dcaf373a0a748536b960b163c16583169358dad5396","first_computed_at":"2026-07-05T01:23:55.225529Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T01:23:55.225529Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"U9vS1oR//UsMEkysrRdC5Qw1XJgEg4l8l405wMYyJ6IbMRbySMu1NnrKwNYU05MH1TsGVEjrVCfL/suxVyMbAw==","signature_status":"signed_v1","signed_at":"2026-07-05T01:23:55.225908Z","signed_message":"canonical_sha256_bytes"},"source_id":"1910.04956","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:add42de2c875c31b15972864616643bd86f0153f3c1930ce7a8d491e428238f4","sha256:c51c22f7728171e5c227d026a6556b9accb6430d764bc9c245f94aa5aac513f8"],"state_sha256":"68aed84fb6d4c22e15dd5d6618c49f929f21ed3c9a0dfddcfc3bc9f5de9baddc"}
