bert-base-multilingual-cased-finetuned-naija

Model description

bert-base-multilingual-cased-finetuned-naija is a Nigerian-Pidgin BERT model obtained by fine-tuning bert-base-multilingual-cased model on Nigerian-Pidgin language texts. It provides better performance than the multilingual BERT on named entity recognition datasets.

Specifically, this model is a bert-base-multilingual-cased model that was fine-tuned on Nigerian-Pidgin corpus.

Intended uses & limitations

How to use

You can use this model with Transformers pipeline for masked token prediction.

>>> from transformers import pipeline
>>> unmasker = pipeline('fill-mask', model='Davlan/bert-base-multilingual-cased-finetuned-naija')
>>> unmasker("Another attack on ambulance happen for Koforidua in March [MASK] year where robbers kill Ambulance driver")

Limitations and bias

This model is limited by its training dataset of entity-annotated news articles from a specific span of time. This may not generalize well for all use cases in different domains.

Training data

This model was fine-tuned on JW300 + BBC Pidgin

Training procedure

This model was trained on a single NVIDIA V100 GPU
