Voyage

Milvus는 VoyageRerankFunction 클래스를 통해 Voyage 리랭커 모델을 지원합니다. 이 기능을 사용하면 쿼리-문서 쌍의 관련성을 효과적으로 점수화할 수 있습니다.

이 기능을 사용하려면 필요한 종속성을 설치하세요:

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

그런 다음 VoyageRerankFunction 을 인스턴스화합니다:

from pymilvus.model.reranker import VoyageRerankFunction

# Define the rerank function
voyage_rf = VoyageRerankFunction(
    model_name="rerank-lite-1",  # Specify the model name. Defaults to `rerank-lite-1`.
    api_key=VOYAGE_API_KEY # Replace with your Voyage API key
)

매개변수

• model_name (문자열)

  인코딩에 사용할 Voyage 모델의 이름입니다. 이 매개변수를 지정하지 않으면 rerank-lite-1 이 사용됩니다. 사용 가능한 모델 목록은 재랭커를 참조하세요.

• api_key (문자열)

  Voyage API에 액세스하기 위한 API 키입니다. API 키를 생성하는 방법에 대한 자세한 내용은 API 키 및 파이썬 클라이언트를 참조하세요.

그런 다음 다음 코드를 사용하여 쿼리를 기반으로 문서의 순위를 재조정합니다:

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 = voyage_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")
