In this setup, we have access to only anomaly-free training data and want to detect and identify anomalies of an arbitrary nature on test data. We employ the density estimates from the energy-based model (EBM) as normalcy scores that can be used to discriminate normal images from anomalous ones. Further, we back-propagate the gradients of the energy score with respect to the image in order to generate a gradient map that provides pixel-level sp","authors_text":"Ergin Utku Genc, Ibrahima J Ndiour, Nilesh Ahuja, Omesh Tickoo","cross_cats":["cs.CV"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.LG","submitted_at":"2021-05-07T13:49:17Z","title":"Energy-Based Anomaly Detection and Localization"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2105.03270","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:c91f73b4d107c16ed40f2ec22cd6974224d894e02436cf5d6e67f4f22fbb4473","target":"record","created_at":"2026-07-05T02:38:23Z","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":"b5c97867cec1dc4db1ab61ddfc6e2b5ebd11d9ab5be980c6263f138a0e65d200","cross_cats_sorted":["cs.CV"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.LG","submitted_at":"2021-05-07T13:49:17Z","title_canon_sha256":"a5f8ca2679e419bd9dc4b17b5ac4a04200a3f9f4c4eb09e380efa0f4a167d506"},"schema_version":"1.0","source":{"id":"2105.03270","kind":"arxiv","version":1}},"canonical_sha256":"427979d9b7986a97f61e05cf9bf6195fcc94fd383cb23d21860695bd2abefb9a","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"427979d9b7986a97f61e05cf9bf6195fcc94fd383cb23d21860695bd2abefb9a","first_computed_at":"2026-07-05T02:38:23.781922Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T02:38:23.781922Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"2lYBrSGp0XLDQqeigCgrx1C9z6JChhoCm3fuFQhDYcIHbV/JgEcsMvDsoNl4Z/759+qTF31KMZPCrutx7SnRBQ==","signature_status":"signed_v1","signed_at":"2026-07-05T02:38:23.782419Z","signed_message":"canonical_sha256_bytes"},"source_id":"2105.03270","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:c91f73b4d107c16ed40f2ec22cd6974224d894e02436cf5d6e67f4f22fbb4473","sha256:359d144a086c692f4a5b7186b9a65aed51019e2676377c4e1a7eae2e20d6467e"],"state_sha256":"f6e7127ccf284ce9991aef53b7b63686b29406204ee9657c38511f0a3dd36353"}
