SentenceTransformer based on BAAI/bge-small-en-v1.5

This is a sentence-transformers model finetuned from BAAI/bge-small-en-v1.5. 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("Snivellus789/router-embedding")
# Run inference
sentences = [
    'How can the person ensure they receive the necessary compensation for their work-related injury?',
    'Is there a law in Oklahoma that restricts the distance of a dispensary to a baseball field?',
    'Considering the complexities of property rights, due process, and public safety, what are the ethical and legal considerations surrounding citizens taking possession of unattended animals in public areas, and how do these actions intersect with constitutional rights and property laws?',
]
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]
