# tgf-xlm-roberta-base-pt-br
This model is a fine-tuned version of [xlm-roberta-base](https://huggingface.co/xlm-roberta-base) on the [BrWac](https://huggingface.co/datasets/thegoodfellas/brwac_tiny) dataset.
## Model description
This is a fine-tuned version of the Brazilian Portuguese language. It was trained using the [BrWac](https://huggingface.co/datasets/thegoodfellas/brwac_tiny) dataset and followed the principles from [Roberta's paper](https://arxiv.org/abs/1907.11692). The key strategies are:
1. *Full-Sentences*: Quoted from the paper: "Each input is packed with full sentences sampled contiguously from one or more documents, such that the total length is at most 512 tokens. Inputs may cross document boundaries. When we reach the end of one document, we begin sampling sentences from the next document and add an extra separator token between documents".
2. Tunned hyperparameters: adam_beta1=0.9, adam_beta2=0.98, adam_epsilon=1e-6 (as paper suggests)
## Availability
The source code is available [here](https://github.com/the-good-fellas/xlm-roberta-pt-br)
