srikarvar/e5-cogcache-small-refined

e5 cogcache small refined

This is a sentence-transformers model finetuned from srikarvar/e5-cogcache-small. It maps sentences & paragraphs to a 384-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("srikarvar/e5-cogcache-small-refined")
# Run inference
sentences = [
    'What is the best way to save money?',
    'Methods for saving money efficiently',
    'Which city is the capital of France?',
]
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]
