Free Split and Merge Expectation Maximization for MultiVariate Gaussian Mixture

by

 

18 Jan 2009 (Updated )

FSMEM can estimate MVGM parameters and number of conpounds via split/merge cluster moves

spiral2d(N)
function Z = spiral2d(N)


t          = rand(1 , N);

temp1      = 2 + 10*t;

temp2      = 7*pi*t;

Z          = [temp1.*sin(temp2) ; temp1.*cos(temp2)] + 0.5*randn(2 , N);
