In this work, we tackle both challenges by leveraging recent advances in \\emph{linear mode connectivity} -- identifying a linearly connected low-loss region in the parameter space of neural networks, which we call solution simplex. We propose federated learning over connected modes (\\textsc{Floco}), where clients are assigned local subregions in this simplex based on their gradient signals, and together le","authors_text":"Dennis Grinwald, Philipp Wiesner, Shinichi Nakajima","cross_cats":["cs.DC"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.LG","submitted_at":"2024-03-05T21:34:23Z","title":"Federated Learning over Connected Modes"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2403.03333","kind":"arxiv","version":4},"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":"sha256:29e03227bd2ef19f32d0fa333bdfd55c4fee5c5dd6c973db3ebe8f68b5382e53","target":"record","created_at":"2026-07-05T10:12:58Z","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":"da6d3b45ac7b7d778fa68bd7142ca90252ce0433c7c39a33216e4ab18ac1a7ea","cross_cats_sorted":["cs.DC"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.LG","submitted_at":"2024-03-05T21:34:23Z","title_canon_sha256":"bc18769ffd5533ed840fe44f5a1c25de936766e90eded5fabcca6911be904c54"},"schema_version":"1.0","source":{"id":"2403.03333","kind":"arxiv","version":4}},"canonical_sha256":"a5b5172cb49627e925d5328e97c37b20d6538d337b83218b3afdd7f2d39bb92c","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"a5b5172cb49627e925d5328e97c37b20d6538d337b83218b3afdd7f2d39bb92c","first_computed_at":"2026-07-05T10:12:58.797783Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T10:12:58.797783Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"WMjNVFADYAdRn1IU+uYvmZRXj+Qv1dyOndIvbOzQeTC1m8jmAJw7uaFDFTpLaKho85wzcO9CmWglw19fvRNhDg==","signature_status":"signed_v1","signed_at":"2026-07-05T10:12:58.798302Z","signed_message":"canonical_sha256_bytes"},"source_id":"2403.03333","source_kind":"arxiv","source_version":4}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:29e03227bd2ef19f32d0fa333bdfd55c4fee5c5dd6c973db3ebe8f68b5382e53","sha256:cdee702c62fb54d2fdd453bbc9a42c4100a49b5b052f00a550706830b700ad0e"],"state_sha256":"70bcbd9ffccf60dee2c045dd47ce5aa8a467d499cc55e9080b6fcd3878f6995c"}
