However, DBSCAN implicitly needs to compute the empirical density for each sample point, leading to a quadratic worst-case time complexity, which is too slow on large datasets. We propose DBSCAN++, a simple modification of DBSCAN which only requires computing the densities for a chosen subset of points. We show empirically that, compared to traditional DBSCAN, DBSCAN++ can provide not only competitive performance but also added robustness in the bandwidth hyperparameter while taking a fraction of the ","authors_text":"Heinrich Jiang, Jennifer Jang","cross_cats":["stat.ML"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.LG","submitted_at":"2018-10-31T04:52:46Z","title":"DBSCAN++: Towards fast and scalable density clustering"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1810.13105","kind":"arxiv","version":3},"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":"sha256:206e5ca64cb74f62edfa36b2a995169e3086be87fd92fc9fdb4d57dd4a0840b6","target":"record","created_at":"2026-05-17T23:45:52Z","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":"50f504f8443693082670369f1444907b088eb064678db6025a3b218022268c8b","cross_cats_sorted":["stat.ML"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.LG","submitted_at":"2018-10-31T04:52:46Z","title_canon_sha256":"c1da6ed2d7fc35f02f4c7041186c0807eefd6960c958dbeb7ed87d5cb0a69b02"},"schema_version":"1.0","source":{"id":"1810.13105","kind":"arxiv","version":3}},"canonical_sha256":"0b212630c88b81f6c40c4ddbd4f5c299b34e0d36fbbfb1303be05157e32fd180","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"0b212630c88b81f6c40c4ddbd4f5c299b34e0d36fbbfb1303be05157e32fd180","first_computed_at":"2026-05-17T23:45:52.655694Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:45:52.655694Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"Zd4VjcOn0cE4ayKiM2TCsX7OeCblrZFDVo+x6ZdXNaQIihApVsiShZfAEd3vGcWqBzxiwWClPILX3mcL2s6qAA==","signature_status":"signed_v1","signed_at":"2026-05-17T23:45:52.656311Z","signed_message":"canonical_sha256_bytes"},"source_id":"1810.13105","source_kind":"arxiv","source_version":3}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:206e5ca64cb74f62edfa36b2a995169e3086be87fd92fc9fdb4d57dd4a0840b6","sha256:95c5e5d59fea816a46f884987f0d633a3e81c84e761bb4860d8cdaf1f3729ff9"],"state_sha256":"24dbad63dbf7de79055fce25dd52930e2c93fbf4ebe29cf3dc4a7b0874390cc7"}
