Inspired by the recent U-statistic based retrospective tests developed by Wang et al.(2019) and Zhang et al.(2020), we advance the U-statistic based approach to the sequential monitoring problem by developing a new adaptive monitoring procedure that can detect both dense and sparse changes in real-time. Unlike Wang et al.(2019) and Zhang et al.(2020), where self-normalization was used in their tests, we instead introduce a class of estimators for $q$-norm of the covarianc","authors_text":"Hao Yan, Runmin Wang, Teng Wu, Xiaofeng Shao","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"stat.ME","submitted_at":"2021-01-18T02:10:28Z","title":"Adaptive Change Point Monitoring for High-Dimensional Data"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2101.06839","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:f4974f91d50f6778aa047765cb6b5980a5dcdd78cad3e7846debdc60c229453e","target":"record","created_at":"2026-07-05T02:07:37Z","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":"ed7422dab760e013f8b61a116224092065a305e99e76a771810c164820123fbf","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"stat.ME","submitted_at":"2021-01-18T02:10:28Z","title_canon_sha256":"5affccaf81722dcdba0f7a91177d738e094cc15927976a98d19dcbdf05e00ac9"},"schema_version":"1.0","source":{"id":"2101.06839","kind":"arxiv","version":1}},"canonical_sha256":"b7b71e5efa1346e19abd157c8f5f8b9fbde8d403560d07733701833e0b757963","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"b7b71e5efa1346e19abd157c8f5f8b9fbde8d403560d07733701833e0b757963","first_computed_at":"2026-07-05T02:07:37.654715Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T02:07:37.654715Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"DiDZG3+K3D8gsEPD8IatjaMqgzk0VFiX4pYGFPXYGeZXPQVPfpjak+K+/pIEoL1dunMwkf8hXmaVxtZpn+PRAg==","signature_status":"signed_v1","signed_at":"2026-07-05T02:07:37.655189Z","signed_message":"canonical_sha256_bytes"},"source_id":"2101.06839","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:f4974f91d50f6778aa047765cb6b5980a5dcdd78cad3e7846debdc60c229453e","sha256:ebcb3e9d7a5d50fa7dd8c965030ee16c8b38d52347937b29214303c6db056c6d"],"state_sha256":"bf1899eb2abcdad31a587e700ef2f4466e53e9bd2b7e8e9c2361f2724205d882"}
