What is Scikit-learn?
The most popular Python machine learning library providing simple and efficient tools for data analysis and modeling.
Scikit-learn provides implementations of classification, regression, clustering, dimensionality reduction, and preprocessing algorithms. Its consistent API makes it easy to swap algorithms: model.fit(X_train, y_train), model.predict(X_test).
Key modules include sklearn.model_selection (cross-validation, grid search), sklearn.preprocessing (scaling, encoding), sklearn.metrics (evaluation), and sklearn.pipeline (workflow chaining). It is the go-to library for traditional machine learning.
