In conventional LSTM-CTC based models, a bottleneck projection matrix maps the hidden feature vectors obtained from LSTM to softmax output layer. In this paper, we propose to use a high rank projection layer to replace the projection matrix. The output from the high rank projection layer is a weighted combination of vectors that are projected from the hidden feature vectors via different projection ma","authors_text":"Mei-Yuh Hwang, Xin Lei, Yangyang Shi","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CL","submitted_at":"2019-03-12T23:40:27Z","title":"End-To-End Speech Recognition Using A High Rank LSTM-CTC Based Model"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1903.05261","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:ea3719ff5a38bf267632b4aea47da7cc9b3d34bc056a5c6d6e6679bb40deaa86","target":"record","created_at":"2026-05-17T23:51:24Z","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":"fb7f97f5a69abb471fb2676334ac9d509687f40b0b455b3da03de22ac11e9665","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CL","submitted_at":"2019-03-12T23:40:27Z","title_canon_sha256":"a597671f1ba72c7a9c3af236c8b0106ab8cd3a9cba77a0a5e10dd85cc685aa2f"},"schema_version":"1.0","source":{"id":"1903.05261","kind":"arxiv","version":1}},"canonical_sha256":"5a6a0f38127949e4de8e1d91c77309413195de034b06c78308d68936c4d7d9be","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"5a6a0f38127949e4de8e1d91c77309413195de034b06c78308d68936c4d7d9be","first_computed_at":"2026-05-17T23:51:24.873721Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:51:24.873721Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"qfeRhq8Uv8L7kHYXHTNzvjGk/WiuzmOm19W5qDN/noqs6Qh+kMl/Fha7jar89PXOjygrz2i/UQJVySFsV2ZfDg==","signature_status":"signed_v1","signed_at":"2026-05-17T23:51:24.874383Z","signed_message":"canonical_sha256_bytes"},"source_id":"1903.05261","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:ea3719ff5a38bf267632b4aea47da7cc9b3d34bc056a5c6d6e6679bb40deaa86","sha256:0966ed39476056f33de3623fb640876c348da00dc20c33440699b8c92ff0dfae"],"state_sha256":"63225bf186ed1d5e8c885b51f0de7be163f6a3ec9841abe3c323ac02e8d5a036"}
