However, integrating online learning into VFL presents challenges due to the unique nature of VFL, where clients possess non-intersecting feature sets for the same sample. In real-world scenarios, the clients may not receive data streaming for the disjoint features for the same entity synchronously. Instead, the data are typically generated by an \\emph{event} relevant to only a subset of clients. We are the first to identify these challenges in online VFL, which have bee","authors_text":"Bin Gu, Boyu Wang, Charles Ling, Ganyu Wang","cross_cats":["cs.DC"],"headline":"","license":"http://creativecommons.org/licenses/by-nc-sa/4.0/","primary_cat":"cs.LG","submitted_at":"2025-06-17T18:41:43Z","title":"Event-Driven Online Vertical Federated Learning"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2506.14911","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":"sha256:26cd19365e683eba74ae3fec20faaaa0a1e1c2a3218f18b1658cc8803f4c73e1","target":"record","created_at":"2026-07-05T11:23:33Z","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":"23e519d759505eda50f19134017a12836fb2f0b411f5c17b61873018e773cfd7","cross_cats_sorted":["cs.DC"],"license":"http://creativecommons.org/licenses/by-nc-sa/4.0/","primary_cat":"cs.LG","submitted_at":"2025-06-17T18:41:43Z","title_canon_sha256":"55944ed2234b18ed46331d839bb57565bee10d99a204ee98d0238dfb88de21b3"},"schema_version":"1.0","source":{"id":"2506.14911","kind":"arxiv","version":1}},"canonical_sha256":"fbc2df0257406cf27aba97d8ce87c56cdf6c15fca602f043fcf130848b534c83","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"fbc2df0257406cf27aba97d8ce87c56cdf6c15fca602f043fcf130848b534c83","first_computed_at":"2026-07-05T11:23:33.904860Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T11:23:33.904860Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"4luzCvYGnK1vnLXNnJjFxuXN1ZGkwFta+0LpbybsfcmT4z9Wbqdjcr/hNNfNvgOHwqZr+AmHWrlsGVgZSZssDw==","signature_status":"signed_v1","signed_at":"2026-07-05T11:23:33.905375Z","signed_message":"canonical_sha256_bytes"},"source_id":"2506.14911","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:26cd19365e683eba74ae3fec20faaaa0a1e1c2a3218f18b1658cc8803f4c73e1","sha256:724b355ae62365f27b2d5dc3bd0a1c6c55c711a05bffda9e478d229b3e9d9a65"],"state_sha256":"59e5c07e073cd8365dd74d88e05007cda8ecf09d114d740c38a0a524bd625b5c"}
