This builtin computes the measure of impurity for the given dataset based on the passed method. The current version expects the target vector to contain only 0 or 1 values and categorical data to be positive integers. Additionally, the builtin expects a row vector R to denote which features are continuous and which are categorical. In case of continuous features, the current implementation applies equal width binning. It returns a row vector with gini gain or information gain for each feature. In both cases, the higher the gain, the better the split. -- This is an automated message from the Apache Git Service.
