SetFit with codefuse-ai/F2LLM-v2-80M

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:

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