scikit-learn is an open-source Python library providing simple and efficient tools for predictive data analysis and machine learning.

scikit-learn is a free software machine learning library for the Python programming language. It features various classification, regression and clustering algorithms including support vector machines, random forests, gradient boosting, k-means, and DBSCAN, and is designed to interoperate with the Python numerical and scientific libraries NumPy and SciPy. The library is built on NumPy, SciPy, and matplotlib, making it accessible for data scientists and developers. It is open source under a BSD license, allowing for commercial use. scikit-learn provides tools for tasks such as model selection, dimensionality reduction, and data preprocessing, supporting a wide range of machine learning applications.
