This is a SetFit model that can be used for Text Classification. This SetFit model uses codefuse-ai/F2LLM-v2-80M 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.

'His first comment was simply a reflex allusion to the fact that French policy is to stay apart from the common military arrangements of the rest of Western Europe.'
"The President and Chancellor agreed during their private meeting on the importance of modernizing the West's nuclear defenses and on the threat of growing Soviet nuclear power, French officials said."
'Senate ratification hearings are scheduled to start on January 25.'

positive

'And you have an escalation in an enormously tense relationship between two countries that have fought three wars, which means you have an enormous amount of destructive capability on a fairly short trigger.'
"It was August 1991, the days and nights of the failed coup d'etat which was meant to restore Stalinism but which brought Boris Yeltsin to power."

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("fefofico/crisis_trained_f2llm_selection")
# Run inference
preds = model("There is talk of five years of austerity.")
