Hi, I do not want to use the random sample as a starting point in gmmdistribution. Rather i want to define my initial guess. But when i am trying to do as per Mathworks instructions,it gives me erro. This is what my situation is:
- pixelList is 40*2 matrix
- k is equal to 2
C is a 2*2 integer matrix with initial guess. I believe,since i am fitting 2 clusters,i should define 2 starting points.Right?
ob = gmdistribution.fit(pixelList,k,'Start',C,'Options',options,'Regularize',1e-5);
It gives me error:
Error using gmcluster (line 158)
'Start' must be 'randSample', a struct or a vector of integers.
Error in gmdistribution.fit (line 174)
[S,NlogL,optimInfo] =...
Please reply and help
