This model can be used for translating text in source language (Fr) to a text in target language (En).
The model is based on Transformer "Big" architecture originally presented in "Attention Is All You Need" paper [1]. In this particular instance, the model has 12 layers in the encoder and 2 layers in the decoder. It is using YouTokenToMe tokenizer [2].
These models were trained on a collection of many publicly available datasets comprising of millions of parallel sentences. The NeMo toolkit [5] was used for training this model over roughly 300k steps.
While training this model, we used the following datasets:
We used the YouTokenToMe tokenizer [2] with shared encoder and decoder BPE tokenizers.
The accuracy of translation models are often measured using BLEU scores [3]. The model achieves the following sacreBLEU [4] scores on the WMT'13 and WMT'14 test sets
WMT13 - 35.5
WMT14 - 40.4
The model is available for use in the NeMo toolkit [5], and can be used as a pre-trained checkpoint for inference or for fine-tuning on another dataset.

This translate method of the NMT model accepts a list of de-tokenized strings.
The translate method outputs a list of de-tokenized strings in the target language.
No known limitations at this time.
