Unformatted text preview: and each data/codebook vector of the input data picks its color from its BMU on the 1-dimensional SOM. If the chaingap argument == 0, the 1-dimensional map has a cylinder (in effect, a ring) topology. Otherwise, the topology is rectangular (in effect, a chain). The colors are mapped to the 1-dimensional SOM simply by picking colors from the color circle. If chaingap>0, a slice of the color circle is removed before map units pick their colors from it. This creates a discontiuity in the coloring at the ends of the 1-dimensional SOM. If the dw argument == 0, the colors are picked from the color circle equidistantly. If not, the distances between the prototype vectors in the 1-dimensional SOM are taken into account. See also SOM_KMEANSCOLOR, SOM_KMEANSCOLOR2, SOM_FUZZYCOLOR. [ SOM Toolbox online doc ]...
