We propose a two-step procedure, IIS-SQDA, where in the first step an innovated interaction screening (IIS) approach based on transforming the original $p$-dimensional feature vector is proposed, and in the second step a sparse quadratic discriminant analysis (SQDA) is proposed for further selecting important interactions and main effects and simultaneously conducting classification. Our IIS approach screens important interactions by examining only $p$ features instead","authors_text":"Daoji Li, Yinfei Kong, Yingying Fan, Zemin Zheng","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"stat.ML","submitted_at":"2015-01-05T22:45:31Z","title":"Innovated interaction screening for high-dimensional nonlinear classification"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1501.01029","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":"sha256:18d689b88ce8aaa3dc7ee532b492d6ba69d2a27c98176e73b5f007ad3cdb8289","target":"record","created_at":"2026-05-18T01:58:26Z","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":"852782b21a8b84556b1dd5ea1e7fbe44450d4568ea35b3e2bfe24e8e5544c85b","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"stat.ML","submitted_at":"2015-01-05T22:45:31Z","title_canon_sha256":"32ab44ff6555f163e34d7ee6d67d3d7d1a581e0dd7a6a761b677c3ee3b26d11b"},"schema_version":"1.0","source":{"id":"1501.01029","kind":"arxiv","version":2}},"canonical_sha256":"9ff58dc834ffe34094656b99889848a19af5392d3f65d67327c81efc5341c7c3","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"9ff58dc834ffe34094656b99889848a19af5392d3f65d67327c81efc5341c7c3","first_computed_at":"2026-05-18T01:58:26.999892Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:58:26.999892Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"T5qdvXs+UObIBqgTqQHlVzTqO4tja+byIUu6mCDoGXS++JUCjcJl2NlRANufcBwOfAxD/fu6fT3GDeJQtDybDw==","signature_status":"signed_v1","signed_at":"2026-05-18T01:58:27.000376Z","signed_message":"canonical_sha256_bytes"},"source_id":"1501.01029","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:18d689b88ce8aaa3dc7ee532b492d6ba69d2a27c98176e73b5f007ad3cdb8289","sha256:a2e75ce2f21133720d1ae305a8c031e6eef2cfee4e1ecdb2f1d09e23070adb1f"],"state_sha256":"c3b96a1b4942f00028c56a927cadf6c4fd5796d9bc67f9960cad9dc1a04b9990"}
