A more efficient detection algorithm can provide more precise early warning, and effectively reduce the decision risk and cost. To date, many methods have been developed to detect signals with spatial structures. However, most of the existing methods are either too conservative for weak signals or computationally too intensive. In this paper, we consider a novel method named Spatial CUSUM (SCUSUM), which employs the idea of the CUSUM procedure and false discovery","authors_text":"Xin Zhang, Zhengyuan Zhu","cross_cats":["cs.LG","stat.ML"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"stat.ME","submitted_at":"2019-04-05T19:25:11Z","title":"Spatial CUSUM for Signal Region Detection"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1904.03246","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":"sha256:012308e78d9eaebd1a4912200e773ae03952f4073a911b40cfcee74adc55bbb7","target":"record","created_at":"2026-05-17T23:49:14Z","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":"fa8ef433116d3ca2a8f24414ddbdfbeaa504880756517a54f190113b3009ca39","cross_cats_sorted":["cs.LG","stat.ML"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"stat.ME","submitted_at":"2019-04-05T19:25:11Z","title_canon_sha256":"d36ebb03e60b328781adb2b2f892b0c068f187e0d170bd652f0497ccc96c2359"},"schema_version":"1.0","source":{"id":"1904.03246","kind":"arxiv","version":1}},"canonical_sha256":"07dd21cf85de870c7015bb25983db6924096343c47202ce30a239e82b31c1d02","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"07dd21cf85de870c7015bb25983db6924096343c47202ce30a239e82b31c1d02","first_computed_at":"2026-05-17T23:49:14.109277Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:49:14.109277Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"k/MLyUhe1gTL7SBiY13NZPAq0HlGNknOuAlxlkOpno4/KB2Ywtygx+Z+4KZ7FH+SNzVa5rpGZDwgGnAfCgd/Aw==","signature_status":"signed_v1","signed_at":"2026-05-17T23:49:14.109981Z","signed_message":"canonical_sha256_bytes"},"source_id":"1904.03246","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:012308e78d9eaebd1a4912200e773ae03952f4073a911b40cfcee74adc55bbb7","sha256:1095d2112e34a58869e82cd3aed355210b01837672ff6c0137334064db577eac"],"state_sha256":"a52bff0fbdd4f7285bf2b6b0ba7ed751fbf0290b0009d12220cbe1986d6cd87a"}
