Zeno generalizes previous results that assumed a majority of non-faulty nodes; we need assume only one non-faulty worker. Our key idea is to suspect workers that are potentially defective. Since this is likely to lead to false positives, we use a ranking-based preference mechanism. We prove the convergence of SGD for non-convex problems under these scenarios. Experimental results show that Zeno outperforms existing approaches.","authors_text":"Cong Xie, Indranil Gupta, Oluwasanmi Koyejo","cross_cats":["cs.CR","cs.DC","stat.ML"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.LG","submitted_at":"2018-05-25T08:33:24Z","title":"Zeno: Distributed Stochastic Gradient Descent with Suspicion-based Fault-tolerance"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1805.10032","kind":"arxiv","version":3},"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":"sha256:62ee9c28c12f01019358f5d9b6a6a50a5c35c9295c9b44fee8e6dfb30787cb4f","target":"record","created_at":"2026-05-17T23:45:53Z","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":"ebb6473cc8cfa6e64f7ed3e1965b78caadbbbf18fa373eb178c206089d1abb20","cross_cats_sorted":["cs.CR","cs.DC","stat.ML"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.LG","submitted_at":"2018-05-25T08:33:24Z","title_canon_sha256":"40640cd246b01df688903ddd27af210825b6c093efd19495ae01cc0372c96455"},"schema_version":"1.0","source":{"id":"1805.10032","kind":"arxiv","version":3}},"canonical_sha256":"e4be916544c2b110b72feb81224ca557326c56423fa38572c7a8533671aeb3c8","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"e4be916544c2b110b72feb81224ca557326c56423fa38572c7a8533671aeb3c8","first_computed_at":"2026-05-17T23:45:53.101905Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:45:53.101905Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"8t/1RvrhUfsIH0V8i11H7JuV/i1xUXdSN8TYVMFARV/kiSx2kfuFaWHDZmoME982j77lM2rNPJy6onPRXcOcBA==","signature_status":"signed_v1","signed_at":"2026-05-17T23:45:53.102426Z","signed_message":"canonical_sha256_bytes"},"source_id":"1805.10032","source_kind":"arxiv","source_version":3}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:62ee9c28c12f01019358f5d9b6a6a50a5c35c9295c9b44fee8e6dfb30787cb4f","sha256:f4a690c869c440821657ae400eb4987e848c1d5c2115c1dc145b4ded2f376a6f"],"state_sha256":"93b9b694c8a391608369778c4ca805d4e8438e0174b5434b5196c6a2dd4c2d20"}
