Analysis of co-evolutionary events among residues has been proved effective to inferring inter-residue contacts. The Markov ran- dom field (MRF) technique, although being widely used for contact prediction, suffers from the following dilemma: the actual likelihood function of MRF is accurate but time-consuming to calculate, in contrast, approximations to the actual likelihood, say pseudo-likelihood, are efficient to calculate but inaccu- rate. Thus, how to achieve both accuracy and ","authors_text":"Dongbo Bu, Fusong Ju, Haicang Zhang, Jianwei Zhu, Minghua Deng, Qi Zhang, Shiwei Sun, Wei-Mou Zheng, Yujuan Gao, Ziwei Xie","cross_cats":["cs.LG","stat.ME"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"q-bio.BM","submitted_at":"2018-08-31T23:38:41Z","title":"Predicting protein inter-residue contacts using composite likelihood maximization and deep learning"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1809.00083","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":"sha256:177287e8872f143102f2279733701451a6be17086d8492516944a6a9bc63a024","target":"record","created_at":"2026-05-18T00:06:36Z","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":"bc5b8003de2d171b0f7250b9b20d90a1075e801d3bdcfa09498b38e9d59d0b69","cross_cats_sorted":["cs.LG","stat.ME"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"q-bio.BM","submitted_at":"2018-08-31T23:38:41Z","title_canon_sha256":"f23c4bbb616ac1d3a9c2577a52ee661620ffc31406392899093c83005be2c720"},"schema_version":"1.0","source":{"id":"1809.00083","kind":"arxiv","version":1}},"canonical_sha256":"b8a577ca7fddb31b9bdd2ebecded4135627dc5aa4f509885b201e5db7d14a9ef","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"b8a577ca7fddb31b9bdd2ebecded4135627dc5aa4f509885b201e5db7d14a9ef","first_computed_at":"2026-05-18T00:06:36.183389Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:06:36.183389Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"lHngKQIfoyl3vNiMn+N8dcHwIZXGgabrDwPVyXISE+/rzTdYXQOGVEZtCLNP0y73uRF5WzY+AkqvZhRCJIP4DA==","signature_status":"signed_v1","signed_at":"2026-05-18T00:06:36.183893Z","signed_message":"canonical_sha256_bytes"},"source_id":"1809.00083","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:177287e8872f143102f2279733701451a6be17086d8492516944a6a9bc63a024","sha256:e9374797d7b203f1ac6d7d1e6cb565c8a79898e42c1b737f724cbfe182eaf12b"],"state_sha256":"03be4a6efc7d710e60ad8c6ada1113b2cc06648fc8c56b9f71ad5a49ad374ca0"}
