SentenceTransformer based on sanganaka/bge-m3-sanskritFT

This is a sentence-transformers model finetuned from sanganaka/bge-m3-sanskritFT. It maps sentences & paragraphs to a 1024-dimensional dense vector space and can be used for retrieval.

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 = [
    "I've been grieving a significant loss for a long time, and while I know I need to move forward, my thoughts constantly pull me back to the past. How do I let go and find peace?",
    'uddhared ātmanātmānaṃ nātmānam avasādayet | ātmaiva hy ātmano bandhur ātmaiva ripur ātmanaḥ ||5||',
    'etair vimuktaḥ kaunteya tamo-dvārais tribhir naraḥ | ācaraty ātmanaḥ śreyas tato yāti parāṃ gatim ||22||',
]
embeddings = model.encode(sentences)
print(embeddings.shape)
# [3, 1024]

# Get the similarity scores for the embeddings
similarities = model.similarity(embeddings, embeddings)
print(similarities)
# tensor([[1.0000, 0.4964, 0.1087],
#         [0.4964, 1.0000, 0.3406],
#         [0.1087, 0.3406, 1.0000]])
