This method has a strong mathematical basis. As opposed to other methods such as Genetic Programming, this method is deterministic, and does not involve the creation of a population of initial solutions. Instead of it, a simple expression is being grown until it fits the data. The experiments performed show that the results are as good as other Machine Learning methods, in a very low computational time. Another advantage of this technique is that the complexity of the expressi","authors_text":"Daniel Rivero, Enrique Fernandez-Blanco","cross_cats":["stat.ML"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.LG","submitted_at":"2019-08-16T10:58:11Z","title":"A New Deterministic Technique for Symbolic Regression"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1908.06754","kind":"arxiv","version":4},"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:aa66567e20da3fe73c01f7debb59093ffa01d855f9e508159fb7e4b01126680d","target":"record","created_at":"2026-07-05T04:06:39Z","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":"6c01df7351f4bef4c97798d38ce40950020a5d28133ed1beb4685aa2bd4be4f6","cross_cats_sorted":["stat.ML"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.LG","submitted_at":"2019-08-16T10:58:11Z","title_canon_sha256":"79b0c5ba111d15ecef75445af1c99a30ac29641e8c0e978a3ec4052b34621b67"},"schema_version":"1.0","source":{"id":"1908.06754","kind":"arxiv","version":4}},"canonical_sha256":"24b80afd59353cdef0421d01bb30048a014db6253c8fd4257f3a2f03ce1ae75b","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"24b80afd59353cdef0421d01bb30048a014db6253c8fd4257f3a2f03ce1ae75b","first_computed_at":"2026-07-05T04:06:39.354119Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T04:06:39.354119Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"/l02d3lRhopybrehudCAFz18g0r1N/PVAFyzmeLQTysA4C+gWtmfjVSBQk3991DgbcMW5Q7c0NM5gUK5DukvDw==","signature_status":"signed_v1","signed_at":"2026-07-05T04:06:39.354556Z","signed_message":"canonical_sha256_bytes"},"source_id":"1908.06754","source_kind":"arxiv","source_version":4}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:aa66567e20da3fe73c01f7debb59093ffa01d855f9e508159fb7e4b01126680d","sha256:b8d54e77e0e1f628632f4aa7f08dc750cc5670a0de74b81e15403277031854fc"],"state_sha256":"ffa9432230dfe5b3e8caa2e5949ea06b8bca5d67d5c9efe5eaff582feaf03dee"}
