scikit-learn

scikit-learn is an open-source collection of machine learning algorithms, including some implementations of the k nearest neighbors. SKLearnVectorStore wraps this implementation and adds the possibility to persist the vector store in json, bson (binary json) or Apache Parquet format.

Installation and Setup

• Install the Python package with pip install scikit-learn

Vector Store

SKLearnVectorStore provides a simple wrapper around the nearest neighbor implementation in the scikit-learn package, allowing you to use it as a vectorstore.

To import this vectorstore:

from langchain_community.vectorstores import SKLearnVectorStore

API Reference:SKLearnVectorStore

For a more detailed walkthrough of the SKLearnVectorStore wrapper, see this notebook.

Retriever

Support vector machines (SVMs) are the supervised learning methods used for classification, regression and outliers detection.

See a usage example.

from langchain_community.retrievers import SVMRetriever

API Reference:SVMRetriever
