# Model description

**XLMR-base-MaCoCu-is** is a large pre-trained language model trained on **Icelandic** texts. It was created by continuing training from the [XLM-RoBERTa-base](https://huggingface.co/xlm-roberta-base) model. It was developed as part of the [MaCoCu](https://macocu.eu/) project and only uses data that was crawled during the project. The main developer is [Jaume Zaragoza-Bernabeu](https://github.com/ZJaume) from Prompsit Language Engineering.

XLMR-base-MaCoCu-is was trained on 4.4GB of Icelandic text, which is equal to 688M tokens. It was trained for 40,000 steps with a batch size of 256. It uses the same vocabulary as the original XLMR-base model.

The training and fine-tuning procedures are described in detail on our [Github repo](https://github.com/macocu/LanguageModels).

## Warning
This model has not been fully trained because it was intended for use as base of [Bicleaner AI Icelandic model](https://huggingface.co/bitextor/bicleaner-ai-full-en-is). If you need better performance, please use [XLMR-MaCoCu-is](https://huggingface.co/MaCoCu/XLMR-MaCoCu-is).

# How to use

```python
from transformers import AutoTokenizer, AutoModel, TFAutoModel

tokenizer = AutoTokenizer.from_pretrained("MaCoCu/XLMR-base-MaCoCu-is")
model = AutoModel.from_pretrained("MaCoCu/XLMR-base-MaCoCu-is") # PyTorch
model = TFAutoModel.from_pretrained("MaCoCu/XLMR-base-MaCoCu-is") # Tensorflow
```

# Data

For training, we used all Icelandic data that was present in the monolingual Icelandic [MaCoCu](https://macocu.eu/) corpus. After de-duplicating the data, we were left with a total of 4.4 GB of text, which equals 688M tokens.
