Generates two-dimensional dataset for classification.
[x,y] = cl_data(N,fname)
- generates data from a mixture of 3
Gaussians and labels them with +/-1
where the first class has two
components and the second class is a single Gaussian.
[x,y] = cl_data(N,fname,row)
- if row is nonzero, then the generated
inputs are on a grid with the size N
(thus the number of examples is
NxN
) and the corresponding inputs are -1,1
