In this paper, a logistic regression model with pairwise interactions among a set of binary covariates is considered. Modeling the structure of the interactions by a graph, our goal is to recover the interaction graph from independently identically distributed (i.i.d.) samples of the covariates and the outcome.\n  When viewed as a feature selection problem, a simple quantity called influence is proposed as a measure of the marginal effects of the interaction te","authors_text":"Easton Li Xu, Shuguang Cui, Tie Liu, Xiaoning Qian","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.AI","submitted_at":"2016-02-12T05:04:21Z","title":"Detection of Cooperative Interactions in Logistic Regression Models"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1602.03963","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":"sha256:219e94e04413ffdcdf668e2a5cc2465ab3af8b533ce70c119eb7fae4e6285372","target":"record","created_at":"2026-05-18T00:53:51Z","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":"6c850c52f258fc9a14f65716d183cf49f0baa0500b2fdd891c0bad4b4e7ec02d","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.AI","submitted_at":"2016-02-12T05:04:21Z","title_canon_sha256":"36246b45723e23c511565df9c906c878760f275304b96f2e7ddf6bbcd9a22aa8"},"schema_version":"1.0","source":{"id":"1602.03963","kind":"arxiv","version":2}},"canonical_sha256":"392a9ecb8cf922c7c68c987863f52746ec2fa0e550bd2de06edef17c60cc4efb","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"392a9ecb8cf922c7c68c987863f52746ec2fa0e550bd2de06edef17c60cc4efb","first_computed_at":"2026-05-18T00:53:51.061847Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:53:51.061847Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"HfWc1enfhV018STWIAFUzW6i+y5pj5XOtTgRTZG92t2iAhKYQjbeHHxA1fSkNkHJrm4vXBOc1jjdLE+RnXOxDQ==","signature_status":"signed_v1","signed_at":"2026-05-18T00:53:51.062347Z","signed_message":"canonical_sha256_bytes"},"source_id":"1602.03963","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:219e94e04413ffdcdf668e2a5cc2465ab3af8b533ce70c119eb7fae4e6285372","sha256:7c5ceeaf6b8dde169308771e502ee0c023ae9b7c1bab3f8ae5cccccbf718febe"],"state_sha256":"94dc5ae336335452518bd4e32dc8b0a22be6ce5e35fdb5110da6891d87cba9f3"}
