SCAMP is motivated from the point of view of non-parametric mixture modeling. Rather than maximizing a classification likelihood to determine cluster assignments, SCAMP casts clustering as a search and selection problem. One consequence of this problem formulation is that the number of clusters is $\\textbf{not}$ a SCAMP tuning parameter. The search phase of SCAMP consists of finding sub-collections of the data matrix, called candidate clusters, that obey shape constraints","authors_text":"Evan Greene, Greg Finak, Raphael Gottardo","cross_cats":["cs.LG"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"stat.ML","submitted_at":"2018-07-26T19:22:20Z","title":"Selective Clustering Annotated using Modes of Projections"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1807.10328","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:defc0e9f95c8d82c8d6e69958761eee3b995bbb604c3e3568ce25c22012770ac","target":"record","created_at":"2026-05-18T00:09:40Z","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":"066bb8729b3da0b95dfb8f49d441ec8fe839240d6f99ad32a73cdf5996ccd126","cross_cats_sorted":["cs.LG"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"stat.ML","submitted_at":"2018-07-26T19:22:20Z","title_canon_sha256":"8aee450a4aae8bb978ad487411150a4cf99fa63362018fe3f96ca6a1f0470fd6"},"schema_version":"1.0","source":{"id":"1807.10328","kind":"arxiv","version":1}},"canonical_sha256":"0d9839409f5c5266f3fc49be8c954346eaceb01b54685084ffca119c2050037b","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"0d9839409f5c5266f3fc49be8c954346eaceb01b54685084ffca119c2050037b","first_computed_at":"2026-05-18T00:09:40.930160Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:09:40.930160Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"dwnVgfJt7vzH2ORa1PTZ/2U7vaW5lE3XL1PPRO2asOpF2kNBioXDyrkekBDX5muV41EBP+qHerXPbabFyRXJDQ==","signature_status":"signed_v1","signed_at":"2026-05-18T00:09:40.930897Z","signed_message":"canonical_sha256_bytes"},"source_id":"1807.10328","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:defc0e9f95c8d82c8d6e69958761eee3b995bbb604c3e3568ce25c22012770ac","sha256:ac524fc6bb0da83443e52e3def241db5f1ef067dcc1a19200259c8cc98ed0479"],"state_sha256":"e3c2a234abeadae78789b105491480161ad62ee2f82516c84500b6714c2bbd6a"}
