Is it possible to optimize this Matlab code for doing vector quantization with centroids from k-means?

I\'ve created a codebook using k-means of size 4000x300 (4000 centroids, each with 300 features). Using the codebook, I then want to label an input vector (for purposes of binning later on). The input[详细]

Most mutually distant k elements (clustering?)

I have a simple machine learning question: I have n (~110) elements, and a matrix of all the pairwise distances. I would like to choose the 10 elements that are most far apart. That is, I want to[详细]
