# NaijaXLM-T-base
This is a XLM-Roberta-base model further pretrained on 2.2 billion Nigerian tweets, described and evaluated in the [reference paper](https://arxiv.org/abs/2403.19260). This model was developed by [@pvcastro](https://huggingface.co./pvcastro) and [@manueltonneau](https://huggingface.co./manueltonneau).

## Training Details

### Training Data

<!-- This should link to a Dataset Card, perhaps with a short stub of information on what the training data is all about as well as documentation related to data pre-processing or additional filtering. -->

The model was further pre-trained on 2.2 billion tweets posted between March 2007 and July 2023 and forming the timelines of 2.8 million Twitter users with a profile location in Nigeria.

### Training Procedure 

<!-- This relates heavily to the Technical Specifications. Content here should link to that section when it is relevant to the training procedure. -->
We performed an adaptive fine tuning of XLM-R on the Nigerian Twitter dataset. 
We kept the same vocabulary as XLM-R and trained the model until convergence for a total of one epoch, using 1\% of the dataset as validation set. The training procedure was conducted in a distributed environment, for approximately 10 days, using 4 nodes with 4 RTX 8000 GPUs each, with a total batch size of 576.
