The utilization of sequential patterns has boosted performance on several kinds of recommendation tasks. Inspired by natural language processing (NLP) techniques, we propose a novel neural network (NN) based next-song recommender, CNN-rec, in this paper. Then, we compare the proposed system with several NN based and classic recommendation systems on the next-song recommendation task. Verification results indicate the proposed system outperforms","authors_text":"Kai-Chun Hsu, Szu-Yu Chou, Tai-Shih Chi, Yi-Hsuan Yang","cross_cats":["cs.AI","cs.LG"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.IR","submitted_at":"2016-06-24T15:25:55Z","title":"Neural Network Based Next-Song Recommendation"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1606.07722","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":"sha256:4ff7b1546ceeecdf4047703791009b8e2292215433eecad840140ecfa9803b1c","target":"record","created_at":"2026-05-18T01:11:55Z","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":"20e7e849450753fc7839d465eab4850ccacf8bbf39adab1935aa126f678c8cdd","cross_cats_sorted":["cs.AI","cs.LG"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.IR","submitted_at":"2016-06-24T15:25:55Z","title_canon_sha256":"0ff00ba5f57d663e0afb1d0371cdbe3c9628f37503148dc458c4191c9a277426"},"schema_version":"1.0","source":{"id":"1606.07722","kind":"arxiv","version":1}},"canonical_sha256":"2ecc678491c616b8ca87e119c65061923802ee78a5c81fbcaafc7d3cc78122a1","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"2ecc678491c616b8ca87e119c65061923802ee78a5c81fbcaafc7d3cc78122a1","first_computed_at":"2026-05-18T01:11:55.835233Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:11:55.835233Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"jCVuoH+3usj4sRL1EIKTRFro4P2Z2f1IRdCkSFtqx+22ROCdjAWrgEaAm1CyHXaRfT1VnIVL3m4mtlN4mXDsAQ==","signature_status":"signed_v1","signed_at":"2026-05-18T01:11:55.835586Z","signed_message":"canonical_sha256_bytes"},"source_id":"1606.07722","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:4ff7b1546ceeecdf4047703791009b8e2292215433eecad840140ecfa9803b1c","sha256:6983559c8a047eacdfb9e936c2ef158d08c66d4281035a8ee86b6c03303e180e"],"state_sha256":"824820c4646021bf12389b7491da31a172dec6a475ba9a8c1247ec6b921d1d75"}
