We propose to develop scalable global monitoring schemes by parallel running local detection procedures and by combining these local procedures together to make a global decision based on SUM-shrinkage techniques. Our approach is illustrated in two concrete examples: one is the nonhomogeneous case when the pre-change and post-change local dist","authors_text":"Kun Liu, Ruizhi Zhang, Yajun Mei","cross_cats":["math.ST","stat.TH"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"stat.ME","submitted_at":"2016-03-29T05:44:26Z","title":"Scalable SUM-Shrinkage Schemes for Distributed Monitoring Large-Scale Data Streams"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1603.08652","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":"sha256:0c483f57733c7e6715abd6486ce098c2b69a9fa13d2124b91110fcb570713df1","target":"record","created_at":"2026-05-18T01:18:05Z","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":"a566d3bf519ca7000e4fe308e9dbdfb877ca5d3a0e66c34bd4e4cceeb09ea45a","cross_cats_sorted":["math.ST","stat.TH"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"stat.ME","submitted_at":"2016-03-29T05:44:26Z","title_canon_sha256":"a85c134f14187016227b28537c1537a1cc4c8e89a5682bcf6c304d7ffb53dcf6"},"schema_version":"1.0","source":{"id":"1603.08652","kind":"arxiv","version":1}},"canonical_sha256":"ac0e3640b5a68b710a11f03d3957e23ce3f1ce9914afb7aea7956c9107649f1f","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"ac0e3640b5a68b710a11f03d3957e23ce3f1ce9914afb7aea7956c9107649f1f","first_computed_at":"2026-05-18T01:18:05.715752Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:18:05.715752Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"G79jablTDC1i0lzi44Zu3m+KobJTStewEIqyZV3efA9XnFJbwmsQODWKE5sE4tT3HbfMXZcpC0SaWhWFIBWuAg==","signature_status":"signed_v1","signed_at":"2026-05-18T01:18:05.716385Z","signed_message":"canonical_sha256_bytes"},"source_id":"1603.08652","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:0c483f57733c7e6715abd6486ce098c2b69a9fa13d2124b91110fcb570713df1","sha256:fcb8d3599dd1237cd94f3c056d6b2edc9df263482510893a5c1fc6281c45f550"],"state_sha256":"e1c35dbeea6dadcff724015aec80e37e6d5dfca8546befb990183ed31978526f"}
