BGE

Milvus es compatible con los modelos reranker BGE a través de la clase BGERerankFunction. Esta funcionalidad permite puntuar eficazmente la relevancia de los pares consulta-documento.

Para utilizar esta función, instale las dependencias necesarias:

pip install --upgrade pymilvus
pip install "pymilvus[model]"

A continuación, instancie la clase BGERerankFunction:

from pymilvus.model.reranker import BGERerankFunction

# Define the rerank function
bge_rf = BGERerankFunction(
    model_name="BAAI/bge-reranker-v2-m3",  # Specify the model name. Defaults to `BAAI/bge-reranker-v2-m3`.
    device="cpu" # Specify the device to use, e.g., 'cpu' or 'cuda:0'
)

Parámetros

• model_name (cadena)

  El nombre del modelo a utilizar. Puede especificar cualquiera de los nombres de modelo de reranker de BGE disponibles, por ejemplo, BAAI/bge-reranker-base, BAAI/bge-reranker-large, etc. Si deja este parámetro sin especificar, se utilizará BAAI/bge-reranker-v2-m3. Para obtener una lista de los modelos disponibles, consulte Lista de modelos.

• device (cadena)

  Opcional. El dispositivo que se utilizará para ejecutar el modelo. Si no se especifica, el modelo se ejecutará en la CPU. Puede especificar cpu para la CPU y cuda:n para el enésimo dispositivo GPU.

A continuación, utilice el siguiente código para clasificar los documentos en función de la consulta:

query = "What event in 1956 marked the official birth of artificial intelligence as a discipline?"

documents = [
    "In 1950, Alan Turing published his seminal paper, 'Computing Machinery and Intelligence,' proposing the Turing Test as a criterion of intelligence, a foundational concept in the philosophy and development of artificial intelligence.",
    "The Dartmouth Conference in 1956 is considered the birthplace of artificial intelligence as a field; here, John McCarthy and others coined the term 'artificial intelligence' and laid out its basic goals.",
    "In 1951, British mathematician and computer scientist Alan Turing also developed the first program designed to play chess, demonstrating an early example of AI in game strategy.",
    "The invention of the Logic Theorist by Allen Newell, Herbert A. Simon, and Cliff Shaw in 1955 marked the creation of the first true AI program, which was capable of solving logic problems, akin to proving mathematical theorems."
]

results = bge_rf(
    query=query,
    documents=documents,
    top_k=3,
)

for result in results:
    print(f"Index: {result.index}")
    print(f"Score: {result.score:.6f}")
    print(f"Text: {result.text}\n")

El resultado esperado es similar al siguiente:
