Model Card

SPLADE-Code-8B is a sparse retrieval model designed for code retrieval tasks.

Usage

Using Sentence Transformers

Install Sentence Transformers:

bash

pip install sentence_transformers

python

from sentence_transformers import SparseEncoder

model = SparseEncoder("naver/splade-code-8B", trust_remote_code=True)

queries = [
    "SELECT *\nFROM Student\nWHERE Age = (\nSELECT MAX(Age)\nFROM Student\nWHERE Group = 'specific_group'\n)\nAND Group = 'specific_group';"
]

query_embeddings = model.encode(queries)
print(query_embeddings.shape)
# torch.Size([1, 151936])

sparsity = model.sparsity(query_embeddings)
print(sparsity)
# {'active_dims': 1120.0, 'sparsity_ratio': 0.9926284751474305}

decoded = model.decode(query_embeddings, top_k=10)
print(decoded)
# [[
#     ('Ġgroup', 2.34375),
#     ('Ġoldest', 2.28125),
#     ('Ġage', 2.25),
#     ('_group', 2.25),
#     ('ĠGroup', 2.171875),
