SOM Toolbox Online documentation http://www.cis.hut.fi/projects/somtoolbox/ som_fuzzycolor [color,X]=som_fuzzycolor(sM,T,R,mode,initRGB,S) SOM_FUZZYCOLOR Heuristic contraction projection/soft cluster color coding for SOM function [color,X]=som_softcolor(map,T,R,mode,initRGB,S) sM (map struct) [T] (scalar) parameter that defines the speed of contraction T<1: slow contraction, T>1: fast contraction. Default: 1 [R] (scalar) number of rounds, default: 30 [mode] (string) 'lin' or 'exp', default: 'lin' [initRGB] (string) Strings accepted by SOM_COLORCODE, default: 'rgb2' [S] (matrix) MxM matrix a precalculated similarity matrix color (matrix) of size MxRx3 resulting color codes at each step X (matrix) of size MxRx2 coordiantes for projected unit weight vectors at each step of iteration. (Color code C is calculated using this projection.) The idea of the projection is to use a naive contraction model which pulls the units together. Units that are close to each other in the output space (clusters)
