SPLADE distilbert-base-uncased trained on python docstring code pairs

This is a SPLADE Sparse Encoder model finetuned from distilbert/distilbert-base-uncased using the sentence-transformers library. It maps sentences & paragraphs to a 30522-dimensional sparse vector space and can be used for semantic search and sparse 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 SparseEncoder

# Download from the 🤗 Hub
model = SparseEncoder("pulkitmehtawork/sparse-distilbert-base-uncased-python-code-lightening")
# Run inference
sentences = [
    'The weather is lovely today.',
    "It's so sunny outside!",
    'He drove to the stadium.',
]
embeddings = model.encode(sentences)
print(embeddings.shape)
# [3, 30522]

# Get the similarity scores for the embeddings
similarities = model.similarity(embeddings, embeddings)
print(similarities)
# tensor([[2148.8340, 1376.2744,  850.4404],
#         [1376.2744, 2056.9260,  898.0439],
#         [ 850.4404,  898.0439, 2509.7507]])
