However, task heterogeneity across clients can cause cross-task interference and gradient conflicts during aggregation. Federated MoE-LoRA addresses this challenge through specialized LoRA experts and conditional routing. Yet existing methods typically specialize at client granularity, implicitly assuming task-coherent clients. Our core insight is that experts need purity, namely pattern-coherent updates that preserve specialization, whereas routers need contrast, namely mixed-task ","authors_text":"Chong Mu, Donghang Duan, Lizong Zhang, Meng Han, Xu Zheng","cross_cats":["cs.CL"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.LG","submitted_at":"2026-07-29T08:47:58Z","title":"FedWeave: Rethinking the Unit of Specialization in Heterogeneous Federated MoE-LoRA"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2607.26618","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":"sha256:2a6d08c122a18eca91066f65f261f1b30d6128bb0ea3e53ee3f6d7b1423a527b","target":"record","created_at":"2026-07-30T01:21:35Z","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":"ff5d3b529cd05d9f45b5a00cf0a02365e44ab27d3f14516d240607b336550e53","cross_cats_sorted":["cs.CL"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.LG","submitted_at":"2026-07-29T08:47:58Z","title_canon_sha256":"d4778a6ab665d66427e9bc08a1a56663d8c3c3a310d49bf84ef4f3b6e83250a6"},"schema_version":"1.0","source":{"id":"2607.26618","kind":"arxiv","version":1}},"canonical_sha256":"0d27c53cc0952f2baa61c8f528cfa7606b67cdf6508eb6c9c4cd5cf5c1018335","receipt":{"builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"0d27c53cc0952f2baa61c8f528cfa7606b67cdf6508eb6c9c4cd5cf5c1018335","first_computed_at":"2026-07-30T01:21:35.654878Z","kind":"pith_receipt","last_reissued_at":"2026-07-30T01:21:35.654878Z","receipt_version":"0.3","signature_status":"unsigned_v0"},"source_id":"2607.26618","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:2a6d08c122a18eca91066f65f261f1b30d6128bb0ea3e53ee3f6d7b1423a527b","sha256:f8fabc686540b01f8121deafa2bef9d6a7e147bd3100c6e604d24be08d6cca5a"],"state_sha256":"fd3e6d024bdb3bcb9625ef658c8a278ce7b01a37e6cea4f12724a2ec91b1a27a"}
