However, most of the works only exploit single type of training data. In this paper, we present a study on classifying bird species by exploiting the combination of both visual (images) and audio (sounds) data using CNN, which has been sparsely treated so far. Specifically, we propose CNN-based multimodal learning models in three types of fusion strategies (early, middle, late) to settle th","authors_text":"Bold Naranchimeg, Chao Zhang, Takuya Akashi","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2018-11-26T06:28:44Z","title":"Cross-domain Deep Feature Combination for Bird Species Classification with Audio-visual Data"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1811.10199","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":"sha256:2d5df4ff4f2373ffb4e480d33dc3f92f8bcffa077f8b8a1ab75d28e241765770","target":"record","created_at":"2026-05-17T23:59:57Z","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":"4830320f57cd27555cee66231caab3780e1ddf09a7ca4b46e7dd2bb549b7149f","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2018-11-26T06:28:44Z","title_canon_sha256":"c837598424342509ddcb8dde10b3860e49b963f0ea3056a0fe9b388c283fb36f"},"schema_version":"1.0","source":{"id":"1811.10199","kind":"arxiv","version":1}},"canonical_sha256":"aee8731b71e4b416277231b090a548791b2a5e18962ec9fc368674aaf9ba734c","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"aee8731b71e4b416277231b090a548791b2a5e18962ec9fc368674aaf9ba734c","first_computed_at":"2026-05-17T23:59:57.160259Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:59:57.160259Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"S64aFoWBd+VbU4YyxAl61K8QrKb7eE/723+D5bsg1DAXrk6s37AKceeCQRxZIz3Q/TdmdJaC+YfJLntZ8gilDA==","signature_status":"signed_v1","signed_at":"2026-05-17T23:59:57.160791Z","signed_message":"canonical_sha256_bytes"},"source_id":"1811.10199","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:2d5df4ff4f2373ffb4e480d33dc3f92f8bcffa077f8b8a1ab75d28e241765770","sha256:a9bf83c70a4a703cfb82a5b984b3124108b63289075cdb9d607b319d5567a092"],"state_sha256":"4352078cbc3c34098019f17067124639ed28378c758e15e812ef540e8adc02b8"}
