Unlike many earlier methods that rely on adversarial learning for feature alignment, we leverage contrastive learning to bridge the domain gap by aligning the features of structurally similar label patches across domains. As a result, the networks are easier to train and deliver better performance. Our approach consistently outperforms state-of-the-art unsupervised and semi-supervised methods on two challenging domain adaptive segmentation tasks, particularly with a small number of ta","authors_text":"Christian Leistner, David Ferstl, Lukas Zebedin, Pascal Fua, Samuel Schulter, Weizhe Liu","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2021-04-22T13:39:12Z","title":"Domain Adaptation for Semantic Segmentation via Patch-Wise Contrastive Learning"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2104.11056","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":"sha256:2bbafa329fcfc811a9d15a2e83e3d84e069b3732704b90e708b1fb88cc5c014f","target":"record","created_at":"2026-07-05T02:34:17Z","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":"dd3c8660c4e52bb67e778faf50e3b0a79127935d03bcb6aad6a8c5ad88900491","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2021-04-22T13:39:12Z","title_canon_sha256":"a6b8c69faa607206f3804217c4b81ff44582f9c995e1cd6b64e62738ef636d51"},"schema_version":"1.0","source":{"id":"2104.11056","kind":"arxiv","version":1}},"canonical_sha256":"9aa196cc080794be93350e3e0f92551e76ef2c5359c5603ba0682e426a12ccb3","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"9aa196cc080794be93350e3e0f92551e76ef2c5359c5603ba0682e426a12ccb3","first_computed_at":"2026-07-05T02:34:17.120195Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T02:34:17.120195Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"jthOoZmxnckoPLtsUldWqG8DftQ5TrU+VGsadEZiO0QA0Au2sSN2bdLPjXWtIVl01P4COOVeoA7VuiIwD78qDw==","signature_status":"signed_v1","signed_at":"2026-07-05T02:34:17.120663Z","signed_message":"canonical_sha256_bytes"},"source_id":"2104.11056","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:2bbafa329fcfc811a9d15a2e83e3d84e069b3732704b90e708b1fb88cc5c014f","sha256:bf9b11d82463d5375fe5ffe066646bc4ba780bf8da19d7a551acd3d22c3a9a70"],"state_sha256":"5971b0fca91df09959ec3a954e671c38cb7e8c898cbea269086c35fb64ef7963"}
