en-toki-mt

This model is a fine-tuned version of Helsinki-NLP/opus-mt-en-ROMANCE on the English - toki pona translation dataset on Tatoeba.

Model description

toki pona is a minimalist constructed language created in 2014 by Sonja Lang. The language features a very small volcabulary (~130 words) and a very simple grammar structure.

Intended uses & limitations

This model aims to translate English to Toki pona.

Training and evaluation data

The training data is acquired from all En-Toki sentence pairs on Tatoeba (~20000 pairs), without any filtering. Since this dataset mostly only includes core words (pu), it may produce inaccurate results when encountering more complex words. The model achieved a BLEU score of 54 on the testing set.
