SetFit

This is a SetFit model that can be used for Text Classification. A LogisticRegression instance is used for classification.

The model has been trained using an efficient few-shot learning technique that involves:

Fine-tuning a Sentence Transformer with contrastive learning.
Training a classification head with features from the fine-tuned Sentence Transformer.

Uses

Direct Use for Inference

First install the SetFit library:

pip install setfit

Then you can load this model and run inference.

from setfit import SetFitModel

# Download from the 🤗 Hub
model = SetFitModel.from_pretrained("rkoh/setfit-bert-a6-8per")
# Run inference
preds = model("The regulations contained in this article govern procedures affecting the appeal to the Board of orders to comply with the Surface Mining and Reclamation Act of 1975 (SMARA) issued by the supervisor of the Division of Mine Reclamation (DMR), or by the Board when acting in the capacity of lead agency pursuant to Public Resources Code Section 2774.4 or 2774.5.")
