It is a task of reconstructing the entire population from a sampling survey of limited size (1% or so), supplying the initial conditions from which simulations begin. This paper presents a new kernel density estimator for this task. Our method is an analogue of the classical Breiman-Meisel-Purcell estimator, but employs novel techniques that harness the huge degree of freedom which is required to model high-dimensional nonlinearly correlated datasets: the crossover kernel, the k-nearest neighbor res","authors_text":"Hideyuki Kikuchi, Hiroyuki Higuchi, Katsumi Homma, Naoki Hamada","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.NE","submitted_at":"2015-08-26T13:22:37Z","title":"Population Synthesis via k-Nearest Neighbor Crossover Kernel"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1508.06483","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":"sha256:210b03d714e278ab2de36628e90acb6a089cf49611c2f078f53e975b56ad7012","target":"record","created_at":"2026-05-18T00:58:57Z","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":"1d50f784fa3a5500e9bb2568e9539d268e8a70a2a37145d3d233a9783e2f3ef2","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.NE","submitted_at":"2015-08-26T13:22:37Z","title_canon_sha256":"40e0a9210ca96a60511fd80e387bd3e1ccb9d4f1e5274164d4b66e1850c8c444"},"schema_version":"1.0","source":{"id":"1508.06483","kind":"arxiv","version":1}},"canonical_sha256":"ce34214f123411b17fa703227f51c437edb414cdd79f63f8587b1ca987497da3","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"ce34214f123411b17fa703227f51c437edb414cdd79f63f8587b1ca987497da3","first_computed_at":"2026-05-18T00:58:57.882553Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:58:57.882553Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"+tNOYUOEAt2rSBnyGUdvqLQ4e/3q0wdVRHPqbmg47Zv8uudalN6DxpD8B3ZYKBbDuq7VLvLMTka+iMASXpu/Dw==","signature_status":"signed_v1","signed_at":"2026-05-18T00:58:57.883024Z","signed_message":"canonical_sha256_bytes"},"source_id":"1508.06483","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:210b03d714e278ab2de36628e90acb6a089cf49611c2f078f53e975b56ad7012","sha256:062b01dcf9f97c61c58b6b905e5204c20559c133abf0c9e28e988e4ad5d95746"],"state_sha256":"e3d1e3f1a7ce658cb826379c9911f40f6811decdc0cc2f11232062fa13391ae5"}
