This additional knowledge generated by pretext tasks can further improve the performance of few-shot learning (FSL) as it differs from human-annotated supervision (i.e., class labels of FSL tasks). To solve this problem, we present a plug-in Hierarchical Tree Structure-aware (HTS) method, which not only learns the relationship of FSL and pretext tasks, but more importantly, can adaptively select","authors_text":"Donglin Wang, Min Zhang, Siteng Huang, Wenbin Li","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2022-07-14T15:17:19Z","title":"Tree Structure-Aware Few-Shot Image Classification via Hierarchical Aggregation"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2207.06989","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":"sha256:94d0ef41a85509d7bb38f1401881ffc9a721882a7330f2e4c451f8984c880aaa","target":"record","created_at":"2026-07-05T04:40:19Z","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":"3e5d627f1eb6df47a7faf9ac5d0dcee519c2f4c570f0e0f8cf24ca7c27057eee","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2022-07-14T15:17:19Z","title_canon_sha256":"da6a2cfc45ccd3673cb6194217188539e981c13eb08f80547e939630cec78137"},"schema_version":"1.0","source":{"id":"2207.06989","kind":"arxiv","version":1}},"canonical_sha256":"86e20047380a3dc8c21ea1256a7b79acdc14a0bb737cb54cd50ed223378651d1","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"86e20047380a3dc8c21ea1256a7b79acdc14a0bb737cb54cd50ed223378651d1","first_computed_at":"2026-07-05T04:40:19.700556Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T04:40:19.700556Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"+hSW1L4/ripSqQig4O7yn+gWw7cFWfkoNBYbHb1B5NKxuhS9coG2FN9waUSmWTEdJBQ39OZK1f2oIblCoRj9AQ==","signature_status":"signed_v1","signed_at":"2026-07-05T04:40:19.701032Z","signed_message":"canonical_sha256_bytes"},"source_id":"2207.06989","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:94d0ef41a85509d7bb38f1401881ffc9a721882a7330f2e4c451f8984c880aaa","sha256:663702d7a5a93d5979c9c077e221fa56f871ee9f720386e01361b002a75383a0"],"state_sha256":"37cd3c85b5b41af0d70d8f235eecd807a76ce031d1f93a1f766835147e1021d3"}
