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 upon NumPy, SciPy, and Matplotlib.

Scikit-learn is one of the most popular machine learning libraries, known for its ease of use and comprehensive documentation. It provides a wide range of algorithms for supervised and unsupervised learning tasks. For supervised learning, it offers algorithms for classification, such as Support Vector Machines (SVM), Logistic Regression, and Decision Trees, as well as regression algorithms like Linear Regression and Ridge Regression. For unsupervised learning, it includes clustering algorithms like K-Means and DBSCAN, and dimensionality reduction techniques such as Principal Component Analysis (PCA).

In addition to algorithms, scikit-learn offers tools for model selection, preprocessing, and evaluation. This includes functions for cross-validation, hyperparameter tuning (e.g., GridSearchCV), and data scaling (e.g., StandardScaler). The library's consistent API makes it easy to switch between different models and experiment with various approaches. Its focus on practical applications and integration with the scientific Python ecosystem has made it a cornerstone for data scientists and machine learning practitioners.
