In supervised machine learning, a common practice to generate ground truth label data is to merge observer annotations. However, as many medical image tasks show a high inter-observer variability resulting from factors such as image quality, different levels of user expertise and domain knowledge, little is known as to how inter-observer va","authors_text":"Alain Jungo, Ekin Ermis, Evelyn Herrmann, Marcela Blatti-Moreno, Mauricio Reyes, Raphael Meier, Roland Wiest","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2018-06-07T08:44:43Z","title":"On the Effect of Inter-observer Variability for a Reliable Estimation of Uncertainty of Medical Image Segmentation"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1806.02562","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":"sha256:0cb22b2d20cce56d552870b2f8711eed6768bffc77e2d914e6cdfabc035724be","target":"record","created_at":"2026-05-18T00:13:56Z","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":"45171d280f4bb6b92a35b7086959152c7ff740c91c90205c11cfa6876cedb3dd","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2018-06-07T08:44:43Z","title_canon_sha256":"34df2d82a48c29b7a110266983b1a125f04997f434616046f36446c47f72358c"},"schema_version":"1.0","source":{"id":"1806.02562","kind":"arxiv","version":1}},"canonical_sha256":"c32ad248b027ae8967bc6ec544405491033aa3cdda5600566e4259137706494d","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"c32ad248b027ae8967bc6ec544405491033aa3cdda5600566e4259137706494d","first_computed_at":"2026-05-18T00:13:56.416543Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:13:56.416543Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"1gvAc97Lnt9z2nwdLwI8rma/WRJiF02aj9U+N9v60CR8UFP7ATrDSSQwyocUyE13ZoU0rpUVzTsXTlDsTA9BDg==","signature_status":"signed_v1","signed_at":"2026-05-18T00:13:56.417159Z","signed_message":"canonical_sha256_bytes"},"source_id":"1806.02562","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:0cb22b2d20cce56d552870b2f8711eed6768bffc77e2d914e6cdfabc035724be","sha256:10241643ddd5d811882e4a652b45d6baad5b06bfc739cf26ab1d9c3ad2cd97bd"],"state_sha256":"a916bca25da63eff6eb49dc83c8061d06e9bb792efb7d2e97b1d9ba4b19edb02"}
