# SetFit

This is a [SetFit](https://github.com/huggingface/setfit) model that can be used for Text Classification. A LinearSVC instance is used for 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.
2. Training a classification head with features from the fine-tuned Sentence Transformer.

## Uses

### Direct Use for Inference

First install the SetFit library:

```bash
pip install setfit
```

Then you can load this model and run inference.

```python
from setfit import SetFitModel

# Download from the 🤗 Hub
model = SetFitModel.from_pretrained("SOUMYADEEPSAR/SetFit_SubjectivityDetection")
# Run inference
preds = model("What could possibly go wrong?")
```
