In this paper, we introduce novel K-center contrastive learning and adjustable decision boundary learning (CLAB) to improve the effectiveness of open intent classification. First, we pre-train a feature encoder on the labeled training instances, which transfers knowledge from known intents to unknown intents. Specifically, we devise a K-center contrastive learning algorithm to ","authors_text":"Benyou Wang, Jianquan Li, Jingjing Mu, Min Yang, Ruifeng Xu, Xiaokang Liu","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.CL","submitted_at":"2023-04-20T11:35:06Z","title":"Effective Open Intent Classification with K-center Contrastive Learning and Adjustable Decision Boundary"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2304.10220","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:d94fbe6c595befac170e4e3b679c09ab1d9aae82803a00a6808fc64281caac4e","target":"record","created_at":"2026-07-05T06:02:55Z","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":"5818c06e0d691c4e311ad8e6372a315b30d2268482b1e9c06236441befc4f0d1","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.CL","submitted_at":"2023-04-20T11:35:06Z","title_canon_sha256":"65ff880ab35da33be6ddb278fd7a51c2db33769e4d0777747d24ef9c73611046"},"schema_version":"1.0","source":{"id":"2304.10220","kind":"arxiv","version":1}},"canonical_sha256":"7fef1feefb0e1c22aab8f068e1eb8af7522acea1d4e0e21e1e2375682e586c25","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"7fef1feefb0e1c22aab8f068e1eb8af7522acea1d4e0e21e1e2375682e586c25","first_computed_at":"2026-07-05T06:02:55.595012Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T06:02:55.595012Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"bC1YRrMu9n7ZtMZKm922j5jIUVmY3a29+5mnkBqfYzr42G2J+mXDI07WSaHt/nQG7m/q6ipkkfZN+03xqCoACQ==","signature_status":"signed_v1","signed_at":"2026-07-05T06:02:55.595469Z","signed_message":"canonical_sha256_bytes"},"source_id":"2304.10220","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:d94fbe6c595befac170e4e3b679c09ab1d9aae82803a00a6808fc64281caac4e","sha256:bc1cb78d6cd17039bdae68a65a35a8490b68030c093a054efecfab7899670c30"],"state_sha256":"65836a037a28dc6b1d90bc2615efa12ca7dddbb6905294e0e0862b93f61720cf"}
