This is a SetFit model that can be used for Text Classification. This SetFit model uses Qwen/Qwen3-Embedding-4B 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.
