For CTR prediction model, it is necessary to capture the latent user interest behind the user behavior data. Besides, considering the changing of the external environment and the internal cognition, user interest evolves over time dynamically. There are several CTR prediction methods for interest modeling, while most of them regard the representation of behavior as the interest directly, and lack specially modeling for latent interest behin","authors_text":"Chang Zhou, Guorui Zhou, Kun Gai, Na Mou, Qi Pi, Weijie Bian, Xiaoqiang Zhu, Ying Fan","cross_cats":["cs.IR","cs.LG"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"stat.ML","submitted_at":"2018-09-11T03:52:37Z","title":"Deep Interest Evolution Network for Click-Through Rate Prediction"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1809.03672","kind":"arxiv","version":5},"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:e97739a01dfb97ad70c9a3856c75325ddd7127e41050f44492f2e9de6465a8d6","target":"record","created_at":"2026-05-18T00:00:34Z","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":"a2bd053709a007c6abf56ea5519888a9fafd88a4c8f56b41351fc5996e3d0957","cross_cats_sorted":["cs.IR","cs.LG"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"stat.ML","submitted_at":"2018-09-11T03:52:37Z","title_canon_sha256":"3611f16e06564d778578d44a11fcda46269b433ee667491d1af49eab3641115e"},"schema_version":"1.0","source":{"id":"1809.03672","kind":"arxiv","version":5}},"canonical_sha256":"e4b560cc3b72ed681ec7fff73150c6b81ac82fc212c61fa7384e41693d633c36","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"e4b560cc3b72ed681ec7fff73150c6b81ac82fc212c61fa7384e41693d633c36","first_computed_at":"2026-05-18T00:00:34.779477Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:00:34.779477Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"uLez+tgnTnJOAl8aVqa7yzeXfcQG1vMKHQKNMLHqM3evBVrBRI1NzvsnWXV4PYjh9pzBcgwczHoDwVF27bQVBA==","signature_status":"signed_v1","signed_at":"2026-05-18T00:00:34.780040Z","signed_message":"canonical_sha256_bytes"},"source_id":"1809.03672","source_kind":"arxiv","source_version":5}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:e97739a01dfb97ad70c9a3856c75325ddd7127e41050f44492f2e9de6465a8d6","sha256:80a6e035c5a7c8b77372d7cd8c7e87f34d7e5cc49f63b15063ca10ae2fef7c45"],"state_sha256":"0d9bf8c608e89adc082783dff62db1d1235c463286395b1c092dafa6af0753a1"}
