Filtering and Extended Vocabulary based Translation for Low-resource Language Pair of Sanskrit-Hindi
Bibliographic record
Abstract
Neural Machine Translation (NMT) is widely employed for language translation tasks because it performs better than the conventional statistical and phrase-based approaches. However, NMT techniques involve challenges, such as requiring a large and clean corpus of parallel data and the inability to deal with rare words. They need to be faster for real-time applications. More work needs to be done using NMT to address the challenges in translating Sanskrit, one of the oldest and rich languages known to the world, with its morphological richness and limited multilingual parallel corpus. There is usually no similar data between a language pair; hence, no application exists so far that can translate Sanskrit to/from other languages. This study presents an in-depth analysis to address these challenges with the help of a low-resource Sanskrit-Hindi language pair. We employ a novel training corpus filtering with extended vocabulary in a zero-shot transformer architecture. The structure of the Sanskrit language is thoroughly investigated to justify the use of each step. Furthermore, the proposed method is analyzed based on variations in sentence length and also applied to a high-resource language pair in order to demonstrate its efficacy.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
