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 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
queries = [
    'For component xyz, returns "xyz[]"',
]
documents = [
    'private static final String getArrayTypeName(String typeName) {\n    final String arrayTypeName = builtInArrayComponentName2ArrayTypeName.get(typeName);\n    return (null == arrayTypeName) ? typeName + ARRAY_TYPE_SUFFIX : arrayTypeName;\n  }',
    'public String toString() {\n\t    \tif(size == 0) {\n\t    \t\treturn "[]";\n\t    \t}else {\n\t    \t\t\n\t    \t\tString result = "[" + elementData[0];\n\t    \t\tfor(int i = 1; i < size; i++) {\n\t    \t\t\tresult += ", " + elementData[i];\n\t    \t\t}\n\t    \t\t\n\t    \t\tresult += "]";\n\t    \t\t\n\t    \t\treturn result;\n\t    \t}\n\t    }',
]
query_embeddings = model.encode_query(queries)
document_embeddings = model.encode_document(documents)
print(query_embeddings.shape, document_embeddings.shape)
# [1, 384] [2, 384]

# Get the similarity scores for the embeddings
similarities = model.similarity(query_embeddings, document_embeddings)
print(similarities)
# tensor([[0.4896, 0.4966]])
