The tfc-SE module consists of two parts: tf-SE block and c-SE block which are designed to provide attention on time-frequency and channel domain, respectively, for adaptively recalibrating the input feature map. The proposed tfc-SE module, together with a popular Convolutional Recurrent Neural Network (CRNN) model, are evaluated on a multi-channel sound event detection task with overlapping au","authors_text":"Kazuhito Koishida, Wei Xia","cross_cats":["cs.LG","cs.SD"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"eess.AS","submitted_at":"2019-08-04T20:58:52Z","title":"Sound Event Detection in Multichannel Audio using Convolutional Time-Frequency-Channel Squeeze and Excitation"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1908.01399","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":"sha256:6c0ad5ed116fe8cb8b7115757bf6946c58aff0d1a4c781217ad488c13215b7d9","target":"record","created_at":"2026-07-04T23:51:30Z","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":"5b632c3cc42fcf7175950366c4c1c1fa0e2336a023e0affec30cfdad5b200f1f","cross_cats_sorted":["cs.LG","cs.SD"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"eess.AS","submitted_at":"2019-08-04T20:58:52Z","title_canon_sha256":"29c25fde77eaa5d62da993d57ccba4ad0b2ab3dfa4594f0e4a25d74f6bb38eb7"},"schema_version":"1.0","source":{"id":"1908.01399","kind":"arxiv","version":1}},"canonical_sha256":"2aec0a0ce8ac2be19a7709fdc319df39e9f82d5ac2e8d4c03ecb79bd292a7e2e","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"2aec0a0ce8ac2be19a7709fdc319df39e9f82d5ac2e8d4c03ecb79bd292a7e2e","first_computed_at":"2026-07-04T23:51:30.052431Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-04T23:51:30.052431Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"6Gktz7hkvJTpn/EjxcSpufLVtgROgI0cTpCGYdBMY6qIIinMmPpQMmpdEqT+g4Ubd8ENfgJqh7RfK2tV67JoAA==","signature_status":"signed_v1","signed_at":"2026-07-04T23:51:30.052845Z","signed_message":"canonical_sha256_bytes"},"source_id":"1908.01399","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:6c0ad5ed116fe8cb8b7115757bf6946c58aff0d1a4c781217ad488c13215b7d9","sha256:36b27d126f15a53b5cbd06df36ab3b765318ed8c88651373db67f3b3fc1bd0fa"],"state_sha256":"86517e1ff8dc98cf8bf235e1e0b6d89c4d1db806c2d312aa606ed9594b03dde2"}
