Model description

This model was obtained by fine-tuning the m2m100_418M model on a Zh-Ca machine translation task with the ca_zh_wikipedia dataset that has been created along with the model. We also evaluate it on a general-domain multilingual testset Flores-101.

Intended uses and limitations

You can use this model for machine translation from Chinese to Catalan.

How to use

from transformers import AutoTokenizer, AutoModelForSeq2SeqLM

tokenizer = AutoTokenizer.from_pretrained("projecte-aina/m2m100_418M_ft_zh_ca")

model = AutoModelForSeq2SeqLM.from_pretrained("projecte-aina/m2m100_418M_ft_zh_ca")

Training

Training data

As a data for fine-tuning we used the ca_zh_wikipedia dataset extracted from Wikipedia.

Training procedure

Tokenization

The original m2m100_418M model's sentencepiece tokenizer was used. The fine-tuning dataset that contained both simplified and traditional Chinese was reduced to its simplified form.

Hyperparameters

The model was trained for 15 epochs with the default parameters and \(LR = 2\mathrm{e}{-5}\).

Evaluation

Variable and metrics

We use the BLEU score for evaluation on test sets: Flores-101.

Evaluation results

Below are the evaluation results on the machine translation from Catalan to Chinese compared with the original m2m100 on a testset: Flores-101.
