In this paper we present a new counter-based algorithm for tracking CHHs, formally prove its error bounds and correctness and show, through extensive experimental results, that our algorithm outperforms the Misra--Gries based algorithm with regard to accuracy and speed whilst requiring asymptotically much less space.","authors_text":"Italo Epicoco, Marco Pulimeno, Massimo Cafaro","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.DS","submitted_at":"2016-11-15T17:17:28Z","title":"Fast and Accurate Mining of Correlated Heavy Hitters"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1611.04942","kind":"arxiv","version":2},"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:f045381ab5ce4348a6ac017979a952195f0785b6c44780a4055e5e6056165cba","target":"record","created_at":"2026-05-18T00:46:55Z","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":"11a5dd9a5e479b19e0369884c8a1a194a4f6572aeb18e7b5e4a919a3b0455866","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.DS","submitted_at":"2016-11-15T17:17:28Z","title_canon_sha256":"ef01deccfacd91db5e3eab1510ca78162cc26f216ee138b4a3af10eec62b4e40"},"schema_version":"1.0","source":{"id":"1611.04942","kind":"arxiv","version":2}},"canonical_sha256":"c95c9d4aae29aada1a040f9b9b7200c45668b667e04a361aa9f9fac2262d29f9","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"c95c9d4aae29aada1a040f9b9b7200c45668b667e04a361aa9f9fac2262d29f9","first_computed_at":"2026-05-18T00:46:55.364260Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:46:55.364260Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"meNFhpTm/gHEiraBs/WMyFaTRa4tLr15A7V0U58eDMwRUJV2f+7DtWMZLh74ujHX9ZlKAFZ5XUEgedo01hAuDA==","signature_status":"signed_v1","signed_at":"2026-05-18T00:46:55.364960Z","signed_message":"canonical_sha256_bytes"},"source_id":"1611.04942","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:f045381ab5ce4348a6ac017979a952195f0785b6c44780a4055e5e6056165cba","sha256:00d4d51fbabdaf1283e02d901ae8dfbb450d55debeaf75969ba8da879fecd354"],"state_sha256":"2b3f9f06c17d81f4177d569427af90f7330646107225daef97f13c31dd7af8e7"}
