In contrast, learning from unlabeled data, especially under domain shift, remains a challenge. Motivated by the latest advances, in this survey we review neural unsupervised domain adaptation techniques which do not require labeled target domain data. This is a more challenging yet a more widely applicable setup. We outline methods, from early traditional non-neural methods to pre-trained model transfer. We also revisit the notion of domain, and we ","authors_text":"Alan Ramponi, Barbara Plank","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CL","submitted_at":"2020-05-31T22:34:14Z","title":"Neural Unsupervised Domain Adaptation in NLP---A Survey"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2006.00632","kind":"arxiv","version":2},"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":"sha256:9135f22b19719cdbd235e610201ce7e895c501fd5cf6a72985e89303c5ffcd24","target":"record","created_at":"2026-07-05T01:47:13Z","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":"27c3a834b148767d3965208e0019a4afdd621036e5d450becbe39ffde62ab8bf","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CL","submitted_at":"2020-05-31T22:34:14Z","title_canon_sha256":"1e0e3ad515c316cbfdf4b07940135b57a1128a628f4f5c6a63ef00eb9704a0e2"},"schema_version":"1.0","source":{"id":"2006.00632","kind":"arxiv","version":2}},"canonical_sha256":"a450f69462885c45e5a027601adb4223f793a203b546d537fb267d15ca169c60","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"a450f69462885c45e5a027601adb4223f793a203b546d537fb267d15ca169c60","first_computed_at":"2026-07-05T01:47:13.851101Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T01:47:13.851101Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"D2VVhfpTMFIvLFw9b4uXww8QrT0/vbiWdUv50Fqt5C8mEnGgTAWNKYeTCnHhPFPydP24EPEb44W4ALGbd9GcBQ==","signature_status":"signed_v1","signed_at":"2026-07-05T01:47:13.851558Z","signed_message":"canonical_sha256_bytes"},"source_id":"2006.00632","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:9135f22b19719cdbd235e610201ce7e895c501fd5cf6a72985e89303c5ffcd24","sha256:e4021ff657c9bf5039f3763a3a451264dec56c7f57fc648e5c01ea1fa7c2c0e1"],"state_sha256":"46ca42da900af9833bcf5cfcaa8a709a3ae925da540a728990f53c9617cb5e36"}
