SetFit with NovaSearch/stella_en_400M_v5

This is a SetFit model that can be used for Text Classification. This SetFit model uses NovaSearch/stella_en_400M_v5 as the Sentence Transformer embedding model. A SetFitHead 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 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:

pip install setfit

Then you can load this model and run inference.

from setfit import SetFitModel

# Download from the 🤗 Hub
model = SetFitModel.from_pretrained("setfit_model_id")
# Run inference
preds = model("What is an SRE? Use only Korean in your response and provide a title wrapped in double angular brackets, such as <<SRE>>. Use the keywords 'indicator', 'objective' and 'management'.")
