SentenceTransformer based on microsoft/harrier-oss-v1-270m

This is a sentence-transformers model finetuned from microsoft/harrier-oss-v1-270m. It maps sentences & paragraphs to a 896-dimensional dense vector space and can be used for semantic textual similarity, semantic search, paraphrase mining, text classification, clustering, and more.

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.

from sentence_transformers import SentenceTransformer

# Download from the 🤗 Hub
model = SentenceTransformer("sentence_transformers_model_id")
# Run inference
sentences = [
    "Instruct: Retrieve text with a similar pragmatic profile, including safety, emotion, sentiment, language, and identity-target signals\nQuery: Everyone in my country has been killing each other for years over religion and they're not even different religion just different branches of Christianity and I quickly realised it's all pointless",
    'Instruct: Retrieve text with a similar pragmatic profile, including safety, emotion, sentiment, language, and identity-target signals\nQuery: Me when my family confronts me about all the queer content on my social media URL',
    'Instruct: Retrieve text with a similar pragmatic profile, including safety, emotion, sentiment, language, and identity-target signals\nQuery: Good to see Tomas Rosicky playing tdae #ARSvQPR',
]
embeddings = model.encode(sentences)
print(embeddings.shape)
# [3, 896]

# Get the similarity scores for the embeddings
similarities = model.similarity(embeddings, embeddings)
print(similarities)
# tensor([[1.0078, 0.6172, 0.5234],
#         [0.6172, 1.0000, 0.5859],
#         [0.5234, 0.5859, 1.0000]], dtype=torch.bfloat16)
