This is a SetFit model that can be used for Text Classification. This SetFit model uses BAAI/bge-small-en-v1.5 as the Sentence Transformer embedding model. 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.

Model Labels

Label	Examples
0	'totally overwrought , deeply biased , and wholly designed to make you feel guilty about ignoring what the filmmakers clearly believe are the greatest musicians of all time .' 'why did they deem it necessary to document all this emotional misery ?' 'a film without surprise geared toward maximum comfort and familiarity .'
1	'a moving , if uneven , success .' 'as the dominant christine , sylvie testud is icily brilliant .' "it 's a sharp movie about otherwise dull subjects ."

Uses

Direct Use for Inference

First install the SetFit library:

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("knoxel/setfit-bge-small-sst2-few-shot")
# Run inference
preds = model("a wildly inconsistent emotional experience .")
