Based on the RNN set of a point, we obtain a quantitative influence (i.e., heat) for the point. The heat map provides a global view on the influence distribution in the space, and hence supports exploratory analyses in many applications such as marketing and resource management. To construct such a heat map, we first reduce it to a problem called Region Coloring (RC), which divides the space into disjoint regions within which all the points have the s","authors_text":"Andy Yuan Xue, Jianzhong Qi, Rui Zhang, Xiaoyong Du, Yu Sun","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.DB","submitted_at":"2016-02-01T04:27:39Z","title":"Reverse Nearest Neighbor Heat Maps: A Tool for Influence Exploration"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1602.00389","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":"sha256:1a24abae884c9e1705f6b7c4c280adf956238f17a4300b8acd1ae66b506d77db","target":"record","created_at":"2026-05-18T01:21:25Z","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":"3774d14644de07058c46c2c5f2511281116965c9f84929a29bcbdb1083a95583","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.DB","submitted_at":"2016-02-01T04:27:39Z","title_canon_sha256":"698a69f17e305b3ed33417a84f80095f863edff9dc793d6b20da316d0bce33a0"},"schema_version":"1.0","source":{"id":"1602.00389","kind":"arxiv","version":2}},"canonical_sha256":"1a22a9be1ee4f85e4d302653fbea0897d2f895a4207f27eece82716bfbbd6971","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"1a22a9be1ee4f85e4d302653fbea0897d2f895a4207f27eece82716bfbbd6971","first_computed_at":"2026-05-18T01:21:25.010649Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:21:25.010649Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"qpYPONXlQD32oAVy65yEuUKBG1UjyqOAXNriHNXV6vyI8yd1fP2NfrKe1tv9P/Kai4Xltxe3D/V5iCJ0WGNvBg==","signature_status":"signed_v1","signed_at":"2026-05-18T01:21:25.011401Z","signed_message":"canonical_sha256_bytes"},"source_id":"1602.00389","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:1a24abae884c9e1705f6b7c4c280adf956238f17a4300b8acd1ae66b506d77db","sha256:d74b1614eae9ecc2180af7bd25d8433271f6143fe1956a458703faf9b9ee1e76"],"state_sha256":"10b7b866b267ef172e39e1574a9231cba10f05a511948e50f2f737a0e155f62d"}
