This is a [SetFit model](https://github.com/huggingface/setfit) that can be used for text classification. The model has been trained using an efficient few-shot learning technique that involves:

1. Fine-tuning a [Sentence Transformer](https://www.sbert.net) with contrastive learning ("sentence-transformers/paraphrase-mpnet-base-v2" specifically in this case).
2. Training a classification head with features from the fine-tuned Sentence Transformer.

This model was finetuned with the custom dataset `joshuapsa/gpt-generated-news-sentences`, which is a synthetic dataset containing news sentences and their topics.<br> 
Please refer to this to understand the label meanings of the prediction output.

## Usage

To use this model for inference, first install the SetFit library:

```bash
python -m pip install setfit
```

You can then run inference as follows:

```python
from setfit import SetFitModel

# Download from Hub and run inference
model = SetFitModel.from_pretrained("joshuapsa/setfit-news-topic-sentences")
# Run inference
preds = model(["Tensions escalated in the Taiwan Strait as Chinese and Taiwanese naval vessels engaged in a standoff, raising fears of a potential conflict.",\
 "Following the highway closure in Toronto, transportation officials announce plans for the construction of additional lanes and improved traffic management systems."])
# The underlying model body of the setfit model is a SentenceTransformer model, hence you can use it to encode a raw sentence into dense embeddings:
emb = model.model_body.encode("Your sentence goes here")
```
