We present the recurrent ladder network, a novel modification of the ladder network, for semi-supervised learning of recurrent neural networks which we evaluate with a phoneme recognition task on the TIMIT corpus. Our results show that the model is able to consistently outperform the baseline and achieve fully-supervised baseline performance with only 75% of all labels which demonstrates","authors_text":"Johannes Twiefel, Marian Tietz, Stefan Wermter, Tayfun Alpay","cross_cats":["cs.LG","cs.NE"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CL","submitted_at":"2017-06-07T10:50:47Z","title":"Semi-Supervised Phoneme Recognition with Recurrent Ladder Networks"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1706.02124","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":"sha256:24fe3e02f72ba73e979b720815958fe84b37092c98cd3763e679d5ae390ccafe","target":"record","created_at":"2026-05-18T00:34:57Z","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":"05fbd15c6a15277d587129ce046345a40ebd813595a0b3a3a21b79603228ff65","cross_cats_sorted":["cs.LG","cs.NE"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CL","submitted_at":"2017-06-07T10:50:47Z","title_canon_sha256":"bdadda1c036cb534ed4029bbbf7b177981ff8c2a56f2df01be60c45da4130662"},"schema_version":"1.0","source":{"id":"1706.02124","kind":"arxiv","version":2}},"canonical_sha256":"83e140fdac42aaa4eadf0f9e2e0e068cf27e6108afc10050f6f2182a6aa989dd","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"83e140fdac42aaa4eadf0f9e2e0e068cf27e6108afc10050f6f2182a6aa989dd","first_computed_at":"2026-05-18T00:34:57.158857Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:34:57.158857Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"0DnktRBeY7dxmtpTPTTtu0FjV9uVcj6JNv/K8qGYpevKjSXwr6NldR0NKTPM3F++cM9z7sTTrlkI1dTXXmh5CQ==","signature_status":"signed_v1","signed_at":"2026-05-18T00:34:57.159509Z","signed_message":"canonical_sha256_bytes"},"source_id":"1706.02124","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:24fe3e02f72ba73e979b720815958fe84b37092c98cd3763e679d5ae390ccafe","sha256:75ee3071cc79c207a8e32ac51b67ce66a9abbc0dae995dc647a00007a3aa69dc"],"state_sha256":"6e6fc8b2a347e9deaafb0fe8373f0ed8af7a7676464713968fb321117830d99a"}
