Usage ### Direct Usage (Sentence Transformers) First install the Sentence Transformers library: ```bash pip install -U sentence-transformers ``` Then you can load this model and run inference. ```python from sentence_transformers import SentenceTransformer # Download from the 🤗 Hub model = SentenceTransformer("Hgkang00/FT-triple-2") # Run inference sentences = [ 'Experience frequent headaches and muscle soreness due to my insomnia.', 'I experience frequent headaches and muscle soreness because of my insomnia.', "The struggle to focus during the day is often due to feeling exhausted even after a full night's sleep.", ] embeddings = model.encode(sentences) print(embeddings.shape) # [3, 384] # Get the similarity scores for the embeddings similarities = model.similarity(embeddings, embeddings) print(similarities.shape) # [3, 3] ``` ##
