Tangkhul is a severely under-resourced Tibeto-Burman language spoken primarily in Manipur, India, with virtually no prior natural language processing infrastructure. We describe two systems: (1) a primary system based on ByT5-large fine-tuned on 38,336 Tangkhul-English parallel sentence pairs, and (2) a contrastive system based on mT5-small fine-tuned on the same corpus. Our primary ByT5-large system achieves a corpus BLEU score of 39.97, chrF++ of 58.07, BERTScore F1 of 0.8104, and COMET (w","authors_text":"Agniva Maiti, Chormi Zimik Vashai","cross_cats":["cs.AI"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CL","submitted_at":"2026-06-24T03:54:46Z","title":"Neural Machine Translation for Low-Resource Tangkhul--English"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2606.25365","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":"sha256:86290a76863e454b16ae231140fcc9ac1b6e2d80b8c5365d3d400c3bc142c119","target":"record","created_at":"2026-06-25T01:18:03Z","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":"857b869fe2c6f7af94a28e2627a38f7957af924f34b7f3e52d5bc4a78f775051","cross_cats_sorted":["cs.AI"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CL","submitted_at":"2026-06-24T03:54:46Z","title_canon_sha256":"fcb77ac7bcde3d37d9c5d2eaa93c2ea1d58f7854b0c4e98107bd324736810dbd"},"schema_version":"1.0","source":{"id":"2606.25365","kind":"arxiv","version":1}},"canonical_sha256":"9123d8665f1e6eb89af3fd7ed08e2a7f2092f0dd134faa6c0137741f14e88567","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"9123d8665f1e6eb89af3fd7ed08e2a7f2092f0dd134faa6c0137741f14e88567","first_computed_at":"2026-06-25T01:18:03.314121Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-06-25T01:18:03.314121Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"rvJMDRD2eKmmfa6ZPvueN7/Jj346rbec8ShNkUDE2uHVL0fKpLpzwv0jS2k6eePnyba8LGnSQLr95DKewi7oDQ==","signature_status":"signed_v1","signed_at":"2026-06-25T01:18:03.314506Z","signed_message":"canonical_sha256_bytes"},"source_id":"2606.25365","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:86290a76863e454b16ae231140fcc9ac1b6e2d80b8c5365d3d400c3bc142c119","sha256:520db86e1cf2c114cb59fded8127e38087ebd1eb9feb130fca709ad59bb40aa8"],"state_sha256":"03b77fa168a8226f7f17d8814ea71279a7c6ca76beea04fffe61e06011f1c4be"}
