Generation of Highleyman classes
A = GENDATH(N,LABTYPE)
Generation of a 2-dimensional 2-class dataset A of N objects according to Highleyman.
The two Highleyman classes are defined by 1: Gauss([1 1],[1 0; 0 0.25]). 2: Gauss([2 0],[0.01 0; 0 4]). Class priors are P(1) = P(2) = 0.5
If N is a vector of sizes, exactly N(I) objects are generated for class I, I = 1,2.
LABTYPE defines the desired label type: 'crisp' or 'soft'. In the latter case true posterior probabilities are set for the labels.
Defaults: N = [50,50], LABTYPE = 'crisp'.
