Model Details
Model Description
This is a masked language model trained on Setswana corpora, making it a valuable tool for a range of downstream applications from translation to content creation. It's powered by the PuoData dataset to ensure accuracy and cultural relevance.
- Developed by: Vukosi Marivate (@vukosi), Moseli Mots'Oehli (@MoseliMotsoehli) , Valencia Wagner, Richard Lastrucci and Isheanesu Dzingirai
- Model type: RoBERTa Model
- Language(s) (NLP): Setswana
- License: CC BY 4.0
Usage
Use this model filling in masks or finetune for downstream tasks. Here’s a simple example for masked prediction:
from transformers import RobertaTokenizer, RobertaModel
# Load model and tokenizer
model = RobertaModel.from_pretrained('dsfsi/PuoBERTa')
tokenizer = RobertaTokenizer.from_pretrained('dsfsi/PuoBERTa')
