Such a constraint, for larger data sets, puts at a disadvantage the use of all the classical linkage criteria but the single linkage one. However, it is known that the single linkage clustering algorithm is very sensitive to outliers, produces highly skewed dendrograms, and therefore usually does not reflect the true underlying data structure -- unless the clusters are well-separated. To overcome its limitations, we propose a new hierarchical c","authors_text":"Anna Cena, Maciej Bartoszuk, Marek Gagolewski","cross_cats":["stat.ML"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.LG","submitted_at":"2022-09-13T06:42:53Z","title":"Genie: A new, fast, and outlier-resistant hierarchical clustering algorithm"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2209.05757","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:f5858d1664d6ae81315b0dbb657a0da1e37b64652c263d75f7a6dca4371205b1","target":"record","created_at":"2026-07-05T04:56:50Z","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":"b4585acfd37e8b4c5edc0fe37f26d421406d82b1bc1b3000c5631bfcba6d428c","cross_cats_sorted":["stat.ML"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.LG","submitted_at":"2022-09-13T06:42:53Z","title_canon_sha256":"c670c9142ae6ff53fd9b34252644fe4fb7e2b0cc841b64d8cd1950704e4aa551"},"schema_version":"1.0","source":{"id":"2209.05757","kind":"arxiv","version":1}},"canonical_sha256":"a7cb5ca9a4404a6cbd23afdf292c787b03ffabd676d098b802b3546b2f288fe6","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"a7cb5ca9a4404a6cbd23afdf292c787b03ffabd676d098b802b3546b2f288fe6","first_computed_at":"2026-07-05T04:56:50.062152Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T04:56:50.062152Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"Ewsw+NzEQfhEh8fs8/A18/KsUFrq5EtNcUF+cueyulywYfs11c3ZQ1GOfZHJEIdUwTkCrzlDWO7vDinIPQLXAQ==","signature_status":"signed_v1","signed_at":"2026-07-05T04:56:50.062531Z","signed_message":"canonical_sha256_bytes"},"source_id":"2209.05757","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:f5858d1664d6ae81315b0dbb657a0da1e37b64652c263d75f7a6dca4371205b1","sha256:55546c3dbc0cf5d344412f2c2f391d0ecb2fcc85f2d6cde169e515b94c59708b"],"state_sha256":"b9b4201a7994498a022b0b0cd5d30251cf0acd5f28d718c79c33cb23c1706fc2"}
