Model Card

English-Hawaiian Pidgin Translator | flan-t5-base-eng-hwp

This model is a fine-tuned version of google/flan-t5-base on a English and Hawaiian Pidgin dataset. It achieves the following results on the evaluation set:

—Loss: 1.5058
—Bleu: 4.9532
—Gen Len: 18.8709

Model description

Running the model

The google/flan-t5-base documentation has more details on running the model.

However, to use this model to translate English to Hawaiian Pidgin, enter `"translate English to Hawaiian Pidgin: "` before your statement.

For example, if you would like to translate "I went to Ala Moana today to go shopping" please tokenize all of the following: `"translate English to Hawaiian Pidgin: I went to Ala Moana today to go shopping."`

If you are trying the English-Hawaiian Pidgin Translator space, there is no need for the input prefix, as it is automatically added.

Training and evaluation data

There are not many English-Hawaiian Pidgin parallel corpora that are easily accessible. A parallel dataset, similar to bible_para, was compiled by scraping the Hawaiʻi Pidgin Version (HWP) and the King James Version (KJV) from biblegateway.com. For more information, refer to `get_data.ipynb`.

Intended uses & limitations

Due to a limited set of training and evaluation data, this model has many limitations, such as not knowing certain Hawaiian Pidgin phrases or having trouble with longer sentences.

Training procedure

For more information regarding training, refer to `finetune_FLAN_T5.ipynb`.
