Considered as a promising avenue a decade ago, this direction has been neglected since the advent of deep neural networks. In this context, this paper brings two contributions: first, it shows that despite the recent success of end-to-end holistic models, explicit part learning can boosts classification performance. Second, this work proceeds one step further than recent part-based models (PBM), focusing on how to learn parts without using ","authors_text":"Ewa Kijak, Frederic Jurie, Ronan Sicre, Yannis Avrithis","cross_cats":["cs.IR"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2017-04-12T13:35:03Z","title":"Unsupervised part learning for visual recognition"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1704.03755","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":"sha256:53ffecccf0ad697f51655b28f98106c9e3029df5457bf331ecc076270a50768b","target":"record","created_at":"2026-05-18T00:46:26Z","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":"362e6b2ef2a0984352cfc5282f4e45ec3d0f93dbc925c85356b485cdfde89886","cross_cats_sorted":["cs.IR"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2017-04-12T13:35:03Z","title_canon_sha256":"12d1415a36aa41fc31996488fe0724fee8811dbb297e2558a108e4a11f975da4"},"schema_version":"1.0","source":{"id":"1704.03755","kind":"arxiv","version":1}},"canonical_sha256":"ec91353af41330da35f630d43055e150f7593755afa3fd479047d9cbc27aec03","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"ec91353af41330da35f630d43055e150f7593755afa3fd479047d9cbc27aec03","first_computed_at":"2026-05-18T00:46:26.952723Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:46:26.952723Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"1iEcnkQ3Jj5DhlvXGemci9TIhOzJNYegEkA0f5WKar10aTD6w2zczOlV6ljOoyQfnZLPJxZOFXe2nulQi++kAQ==","signature_status":"signed_v1","signed_at":"2026-05-18T00:46:26.953252Z","signed_message":"canonical_sha256_bytes"},"source_id":"1704.03755","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:53ffecccf0ad697f51655b28f98106c9e3029df5457bf331ecc076270a50768b","sha256:522d2b03203e265806c05bb9e1187393526b8e9357e10e39a9c1b9049eaaaf4a"],"state_sha256":"42042ee6f1807932f3cd0be6c3a38ed68c182a3229fa3e83e84146c8d40ff48e"}
