Bilinear pooling based models have been shown to be effective at fine-grained recognition, while most previous approaches neglect the fact that inter-layer part feature interaction and fine-grained feature learning are mutually correlated and can reinforce each other. In this paper, we present a novel model to address these issues. First, a cross-layer bilinear pooling approach is proposed to capture the inter-layer part feature relations, which r","authors_text":"Chaojian Yu, Peng Zhang, Qi Zheng, Xinge You, Xinyi Zhao","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by-nc-sa/4.0/","primary_cat":"cs.CV","submitted_at":"2018-07-26T01:46:15Z","title":"Hierarchical Bilinear Pooling for Fine-Grained Visual Recognition"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1807.09915","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:ff57eb811a5a4c051b2bcfc8cdc0dce54cc29260a42a51a7994220ea1ef6ea76","target":"record","created_at":"2026-05-18T00:09:46Z","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":"147bd5a1f9a88d35c2fbda1f81372a9bfc31a284d178486e53efb8e868c37350","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by-nc-sa/4.0/","primary_cat":"cs.CV","submitted_at":"2018-07-26T01:46:15Z","title_canon_sha256":"1aab44855f70a03daad6aea48d53c472dd4ec983025d6748c0852ba3bb71d383"},"schema_version":"1.0","source":{"id":"1807.09915","kind":"arxiv","version":1}},"canonical_sha256":"60f9b4827296e285b5e3731d51054104d8d4d5ec961320185f6fd3368a78d29b","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"60f9b4827296e285b5e3731d51054104d8d4d5ec961320185f6fd3368a78d29b","first_computed_at":"2026-05-18T00:09:46.132966Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:09:46.132966Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"bcu/BjrNSn43/HNVPTOhGEJ8ltTNd7EKvfpY9Ph5bPdEHDfw4ZvuReAhElWTBMYVxsX+ASbrrspcZLRZp1T9Cg==","signature_status":"signed_v1","signed_at":"2026-05-18T00:09:46.133688Z","signed_message":"canonical_sha256_bytes"},"source_id":"1807.09915","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:ff57eb811a5a4c051b2bcfc8cdc0dce54cc29260a42a51a7994220ea1ef6ea76","sha256:b25637d784149e0bf32eaa16ad0e82a135d4abb741b48624085546745b886d03"],"state_sha256":"a92ec2ef953399376499efb322e311efcfe561d0711c8d45269873d2d8586b69"}
