However, a typical distributed system is usually implemented with a central server that collects data statistics from multiple independent machines operating on different subsets of data to build a global analytic model. This centralized communication architecture however exposes a single choke point for operational failure and places severe bottlenecks on the server's communication an","authors_text":"Jonathan How, Kian Hsiang Low, Quang Minh Hoang, Trong Nghia Hoang","cross_cats":["cs.DC","stat.ML"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.LG","submitted_at":"2018-05-23T16:26:41Z","title":"Collective Online Learning of Gaussian Processes in Massive Multi-Agent Systems"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1805.09266","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":"sha256:1040ac1c8a08f570242b1f5b790cb720cb10491d1cf62f5415a62af6df9331bf","target":"record","created_at":"2026-05-18T00:01:01Z","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":"f3d93c0c24f3d91ad8722a2f28946324cc84252db3308c9eacc596d743520ed6","cross_cats_sorted":["cs.DC","stat.ML"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.LG","submitted_at":"2018-05-23T16:26:41Z","title_canon_sha256":"eddb8ca3aeabcaaafc33df4da85e28fe78d9940e3582297f86c10b787b0af294"},"schema_version":"1.0","source":{"id":"1805.09266","kind":"arxiv","version":2}},"canonical_sha256":"9a645392abd8740802259f6ccaa26c43aa3ed6da0388ed2220dea6f8939fd734","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"9a645392abd8740802259f6ccaa26c43aa3ed6da0388ed2220dea6f8939fd734","first_computed_at":"2026-05-18T00:01:01.815024Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:01:01.815024Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"87j0Fk0Qg6jSEiCq0fUtYJkInvyYh/YCXEoKogOHLHYRVs9YXRA1auN4Q1oEn3bmPh3n4ZLvO9nML2oGvOW3DA==","signature_status":"signed_v1","signed_at":"2026-05-18T00:01:01.815548Z","signed_message":"canonical_sha256_bytes"},"source_id":"1805.09266","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:1040ac1c8a08f570242b1f5b790cb720cb10491d1cf62f5415a62af6df9331bf","sha256:fdda178c6db2f6a0d8327eb8120af9fddeee5b9732c8ec099fe6280c99589df8"],"state_sha256":"a7cfc933f8047e8eda6581267360950d52bea5087badc4377fd450cd44268625"}
