Hi, To represent our data (3233477*256) with Bag of visual word (BOW) which use KMeans clustering to extract visual words when we choose K=5000 this problem show:
Error using pdist2mex
Requested 3233477x5000 (120.5GB) array exceeds maximum array size preference. Creation of arrays greater than this limit may take a
long time and cause MATLAB to become unresponsive. See array size limit or preference panel for more information.
Error in kmeans>distfun (line 747)
D = pdist2mex(X,C,'sqe',[],[],[]);
Error in kmeans/loopBody (line 445)
D = distfun(X, C, distance, 0, rep, reps);
Error in internal.stats.parallel.smartForReduce (line 136)
reduce = loopbody(iter, S);
Error in kmeans (line 335)
ClusterBest = internal.stats.parallel.smartForReduce(...
Error in BOWHistogram (line 12)
[idx,c,sumd,D2] = kmeans(double(Tab_Feature_Data),NumClust);
What can I do to fix the error? Please advise me
