Scikit-learn is a widely-used open-source machine learning library in Python that provides simple and efficient tools for data mining and data analysis. It offers a range of supervised and unsupervised learning algorithms, making it suitable for tasks like classification, regression, and clustering, as well as essential features for model evaluation and selection. This library plays a significant role in feature selection and extraction processes, helping users identify the most relevant features from their datasets to improve model performance.
