Usage

Direct Usage (Sentence Transformers)

First install the Sentence Transformers library:

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("deepali1021/finetuned_arctic_ft-v2")
# Run inference
sentences = [

    "responsible for familiarizing themselves with the latest version of the manual. \n \nConclusion \nThank you for reviewing our HR Policy Manual. It serves as a guide to ensure a positive and inclusive \nwork environment. If you have any questions or need further information, please reach out to the HR \ndepartment. We value your contributions and commitment to our company's success.",

embeddings = model.encode(sentences)
print(embeddings.shape)
# [3, 1024]

# Get the similarity scores for the embeddings
similarities = model.similarity(embeddings, embeddings)
print(similarities.shape)
# [3, 3]
