Albeit great effort made in single source domain adaptation, a more generalized task with multiple source domains remains not being well explored, due to knowledge degradation during their combination. To address this issue, we propose a novel approach, namely target-relevant knowledge preservation (TRKP), to unsupervised multi-source DAOD. Specifically, TRKP adopts the teacher-student framework, where the multi-head teacher network is built to extract knowledge from labeled sou","authors_text":"Bingqi Ma, Bo Li, Di Huang, Jiaxin Chen, Jiaxi Wu, Mengzhe He, Weihao Gan, Wei Wu, Yali Wang, Yiru Wang","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2022-04-17T09:50:48Z","title":"Target-Relevant Knowledge Preservation for Multi-Source Domain Adaptive Object Detection"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2204.07964","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":"sha256:20213376ffb001f4ea644b4c226ddf2a97072539332d9598252429425fb7365d","target":"record","created_at":"2026-07-05T04:15:20Z","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":"544e2f38bc58cef2ec29ce9b2cd47f265f7870880305aa26d5eeba7923f239a6","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2022-04-17T09:50:48Z","title_canon_sha256":"f3cf8c2682338b6b877609e0768000150e8cb792abb9b02c0a465e49aefad4cf"},"schema_version":"1.0","source":{"id":"2204.07964","kind":"arxiv","version":1}},"canonical_sha256":"f81d6427cce4a12960a9ef2306014d6728210d471e1a5926b2906c25a19d1341","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"f81d6427cce4a12960a9ef2306014d6728210d471e1a5926b2906c25a19d1341","first_computed_at":"2026-07-05T04:15:20.500024Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T04:15:20.500024Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"QzFBlYvJmZ2a3knLR+Oz1JNTtJh6Up6/RJUuO1kB/9TqjAhqI1LHdr6H5Jq07q82WsDa/VKClt4gh5R9zkn/Bg==","signature_status":"signed_v1","signed_at":"2026-07-05T04:15:20.500489Z","signed_message":"canonical_sha256_bytes"},"source_id":"2204.07964","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:20213376ffb001f4ea644b4c226ddf2a97072539332d9598252429425fb7365d","sha256:f12fea4ac5a0d7c18373f7444c835cb735139a095189112a9084f07741020498"],"state_sha256":"3574bab8cc28272582e1d8019db1c7b13056b762243be1a17fab8d537dc92e4c"}
