scripts default iconKernel k-means (Scripts) Publisher's description

This function performs kernel version of kmeans algorithm

This function performs kernel version of kmeans algorithm. When the linear kernel (i.e., inner product) is used, the algorithm is equivalent to standard kmeans algorithm.

K: n x n a semi-definite matrix computed by a kernel function on all sample pairs
m: the number of clusters k (1 x 1) or the initial label of samples (1 x n, 1<=label(i)<=k)

reference: [1] Kernel Methods for Pattern Analysis
by John Shawe-Taylor, Nello Cristianini

sample code:
load data;
K=x'*x; % use linear kernel

System Requirements:

MATLAB 7.9 (2009b)
Program Release Status: Major Update
Program Install Support: Install and Uninstall
