# Fine-tuned RoBERTa-large for detecting news on politics
# Model Description
This model is a finetuned RoBERTa-large, for classifying whether news articles are about politics.
# How to Use
```python
from transformers import pipeline
classifier = pipeline("text-classification", model="dell-research-harvard/topic-politics")
classifier("Kennedy wins election")
```
# Training data
The model was trained on a hand-labelled sample of data from the [NEWSWIRE dataset](https://huggingface.co/datasets/dell-research-harvard/newswire).
