SentenceTransformer based on sentence-transformers/LaBSE

This is a sentence-transformers model finetuned from sentence-transformers/LaBSE on the mitrasamgraha dataset. It maps sentences & paragraphs to a 768-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("sanganaka/LaBSE-sanskritFT")
# Run inference
sentences = [
    'O Śākyamuni, conquering the powerful host of Māra, You found peace, immortality, and the happiness of that supreme enlightenment',
    'मारस् त्वयास्तु विजितस् सबलो मुनीन्द्रः प्राप्ता शिवा अमृतशान्तवराग्रबोधिः ।',
    'न हि तथता द्वयप्रभाविता नानात्वप्रभाविता ।',
]
embeddings = model.encode(sentences)
print(embeddings.shape)
# [3, 768]

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