Model description

This model was obtained by fine-tuning the m2m100_418M model on a De-Ca machine translation task with the Softcatalà Catalan-German parallel corpus dataset, with sentences deduplicated and filtered by the GEnCaTa quality filter. We also evaluate it on a general-domain multilingual testset Flores-200 and WMT13.

Intended uses and limitations

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

How to use

from transformers import AutoTokenizer, AutoModelForSeq2SeqLM

tokenizer = AutoTokenizer.from_pretrained("projecte-aina/2m100-418M-ft-de-ca")

model = AutoModelForSeq2SeqLM.from_pretrained("projecte-aina/2m100-418M-ft-de-ca")

Training

Training data

As a data for fine-tuning we used the Softcatalà Catalan-German parallel corpus dataset, with sentences deduplicated and filtered by the GEnCaTa quality filter.

Training procedure

Tokenization

The original m2m100_418M model's sentencepiece tokenizer was used.

Hyperparameters

The model was trained for 2 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-200 and WMT13.

Evaluation results

Below are the evaluation results on the machine translation from German to Catalan compared with the original m2m100 on a testset: Flores-200.

Test set Model BLEU TER METEOR chrF
Flores-200 m2m100 26.6 63.1 54.0 53.5
