**What it does**
Linear Discriminant Analysis and Quadratic Discriminant Analysis are two classic classifiers, with, as their names suggest, a linear and a quadratic decision surface, respectively. This module uses sklearn.discriminant_analysis package to implement Discriminant Analysis classification.
