In addition to achieving reliable accuracy, a critical subtask for these models is to detect Out-of-distribution (OOD) inputs. Given the nature of the deployment environment, one may expect such OOD inputs to also be fine-grained w.r.t. the known classes (e.g., a novel bird species), which are thus extremely difficult to identify. Unfortunately, OOD detection in fine-grained scenarios remains largely underexplored.","authors_text":"Hai Li, Jingyang Zhang, Nathan Inkawhich, Randolph Linderman, Yiran Chen","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.LG","submitted_at":"2021-06-07T19:01:17Z","title":"Mixture Outlier Exposure: Towards Out-of-Distribution Detection in Fine-grained Environments"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2106.03917","kind":"arxiv","version":4},"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":"sha256:983662832e0bdffeeaa2097454b56128f65a775b4a3e707610903efdae2ef0e1","target":"record","created_at":"2026-07-05T05:08:25Z","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":"ac53c548adeb070e9be7447412e1488d1ef6c8a3de3631aaa4db3b9426db385d","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.LG","submitted_at":"2021-06-07T19:01:17Z","title_canon_sha256":"73c395e7588c5da3adaba252eadc7d091f531d95e1fc8c16341ecc4ff3635a2a"},"schema_version":"1.0","source":{"id":"2106.03917","kind":"arxiv","version":4}},"canonical_sha256":"dbbc13cae0f7abe186657a9c54e2abd015d44eceb65d1df937635c230926b97a","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"dbbc13cae0f7abe186657a9c54e2abd015d44eceb65d1df937635c230926b97a","first_computed_at":"2026-07-05T05:08:25.053432Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T05:08:25.053432Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"Wzv3nY3FKfpZLBx6NfmqyeMGnNB1QAZLn2c+pfUSXw2fj5qzytrcYKsg46me9nviSuJOJ6rtrCdo15qbbeSiAw==","signature_status":"signed_v1","signed_at":"2026-07-05T05:08:25.053836Z","signed_message":"canonical_sha256_bytes"},"source_id":"2106.03917","source_kind":"arxiv","source_version":4}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:983662832e0bdffeeaa2097454b56128f65a775b4a3e707610903efdae2ef0e1","sha256:06b2dee49c61a453d38726256091c529c3919be12389eb8045952d34ca9fc0b0"],"state_sha256":"87d684130faac1a29a6ad4db9dbe354db1400b4ca5c88a37c77b93af4c198009"}
