# moshew/bge-small-en-v1.5_setfit-sst2-english
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) ("BAAI/bge-small-en-v1.5") with contrastive learning.
2. Training a classification head with features from the fine-tuned Sentence Transformer.
## Training code
```python
from setfit import SetFitModel
from datasets import load_dataset
from setfit import SetFitModel, SetFitTrainer
# Load a dataset from the Hugging Face Hub
dataset = load_dataset("SetFit/sst2")
# Upload Train and Test data
num_classes = 2
test_ds = dataset["test"]
train_ds = dataset["train"]
model = SetFitModel.from_pretrained("BAAI/bge-small-en-v1.5")
trainer = SetFitTrainer(model=model, train_dataset=train_ds, eval_dataset=test_ds)
# Train and evaluate
trainer.train()
trainer.evaluate()['accuracy']
```
## 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("moshew/bge-small-en-v1.5_setfit-sst2-english")
# Run inference
preds = model(["i loved the spiderman movie!", "pineapple on pizza is the worst 🤮"])
```
## Accuracy
On SST-2 dev set:
91.4% SetFit
88.4% (no Fine-Tuning)
