First, we train a model that detects machine activity by using normal data with machine activity labels and then use the activity-detection error as the anomaly score for a given sound clip if we have access to the ground-truth activity labels in the inference phase. If these labels are not available, the anomaly score is calculated through outlier detection on the embedding vectors obtained by the activity-detection","authors_text":"Kota Dohi, Masaaki Yamamoto, Takashi Endo, Tomoya Nishida, Yohei Kawaguchi","cross_cats":["cs.LG","cs.SD"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"eess.AS","submitted_at":"2022-04-15T07:23:32Z","title":"Anomalous Sound Detection Based on Machine Activity Detection"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2204.07353","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:f6c6e04f119555baf6411cf8ff0c52397d9bae68dfdf1802ba3ee462d50e89de","target":"record","created_at":"2026-07-05T04:15:03Z","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":"7d7c411168759cb58afd0a1e6e16228aac492de8748b2c01c85deae6ac6562e6","cross_cats_sorted":["cs.LG","cs.SD"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"eess.AS","submitted_at":"2022-04-15T07:23:32Z","title_canon_sha256":"5c848c1478621d081f77624237f94084164f706a7f692de94e667cb48a904265"},"schema_version":"1.0","source":{"id":"2204.07353","kind":"arxiv","version":1}},"canonical_sha256":"f4bc05c9bba7ef701bf6604d9ebe28aa7591449d26776e8ce47081c1a7fb7ea1","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"f4bc05c9bba7ef701bf6604d9ebe28aa7591449d26776e8ce47081c1a7fb7ea1","first_computed_at":"2026-07-05T04:15:03.086911Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T04:15:03.086911Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"vnRL2Yb6hL7cIH5MemzZRSXKRl+BvccnPzT36tPtlIx23pZHFm67e4q3N/6AzX3LDP7Rpayni4751yw+30qnAQ==","signature_status":"signed_v1","signed_at":"2026-07-05T04:15:03.087403Z","signed_message":"canonical_sha256_bytes"},"source_id":"2204.07353","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:f6c6e04f119555baf6411cf8ff0c52397d9bae68dfdf1802ba3ee462d50e89de","sha256:9aae405f969fc32e4e567ed8dcaaaac9d40be7ffef656c73622fe0b822a79d2c"],"state_sha256":"71b8bedd4eb08fd8ef8fa995d19e660b3199bdff5e8d56c30925b4632d2377e2"}
