NUMCLUSTERS must be a positive integer not greater than the number of data

I am using the vl_feat module to call sift and gmm model for my data of 600 images. But I got the error for numCluster when I run GMM model. I set numClusters to 32,64, and 128 and kd to 16 and 32 and I got the error. If anyone know how to fix problem, please help me. Thanks and appreciate a lot.

After that dimension reduction, you are left with an array that has kd = 16 columns. For vl_gmm, each column is an independent sample, so that means that you are passing in only 16 different samples. But you are asking to divide those 16 different samples into 64 clusters.

You know how can apply vl_gmm in this problem?

[Walter Roberson]

My guess would be that you should be passing the transpose of x into vl_gmm

Thanks you so much for your help.
