What is scikit-learn?
scikit-learn is a machine learning library for Python that provides simple and efficient tools for predictive data analysis. It is built on NumPy, SciPy, and matplotlib, and is open source under the BSD license, so it can also be used commercially. It offers classification, regression, clustering, dimensionality reduction, model selection, and preprocessing. It is developed with support from organizations and individuals who back open-source machine learning, and Probabl provides enterprise solutions and services.
- Classification (gradient boosting, nearest neighbors, random forest, logistic regression, etc.)
- Regression (ridge, etc.)
- Clustering (k-Means·HDBSCAN·hierarchical clustering)
- Dimensionality reduction (PCA·feature selection·NMF)
- Model selection (grid search·cross-validation·metrics)
- Preprocessing and feature extraction
Who uses scikit-learn and for what
- Classification such as spam detection and image recognition
- Continuous value prediction such as drug response and stock prices
- Cluster analysis such as customer segmentation
