sklearn.discriminant_analysis.QuadraticDiscriminantAnalysis The Linear Discriminant Analysis is available in the scikit-learn Python machine learning library via the LinearDiscriminantAnalysis class. The method can be used directly without configuration, although the implementation does offer arguments for customization, such as the choice of solver and the use of a penalty. Watch the full KDA documentation here. In machine learning, There are different types of kernel-based approaches such as Regularized Radial Basis Function (Reg RBFNN), Support Vector Machine (SVM), Kernel-fisher … Linear Discriminant Analysis from scratch | Kaggle QDA assumes that each class follow a Gaussian distribution.
