SOM Toolbox Online documentation http://www.cis.hut.fi/projects/somtoolbox/ som_batchtrain Purpose Trains a Self-Organizing Map using the batch algorithm. Syntax sM = som_batchtrain(sM,D); sM = som_batchtrain(sM,sD); sM = som_batchtrain(. ..,'argID',value,. ..); sM = som_batchtrain(. ..,value,. ..); [sM,sT] = som_batchtrain(M,D,. ..); Description Trains the given SOM (sM or M above) with the given training data (sD or D) using batch training algorithm. If no optional arguments (argID, value) are given, a default training is done. Using optional arguments the training parameters can be specified. Returns the trained and updated SOM and a train struct which contains information on the training. References Kohonen, T., "Self-Organizing Map", 2nd ed., Springer-Verlag, Berlin, 1995, pp. 127-128. Kohonen, T., "Things you haven't heard about the Self-Organizing Map", In proceedings of International Conference on Neural Networks (ICNN), San Francisco, 1993, pp. 1147-1156. Known bugs Batchtrain does not work correctly for a map with a single unit. This is because of the way 'min'-function works. Required input arguments sM The map to be trained. (struct) map struct

(matrix) codebook matrix (field .data of map struct) Size is either [munits dim], in which case the map grid dimensions (msize) should be specified with optional arguments, or [msize(1) . .. msize(k) dim] in which case the map grid dimensions are taken from the size of the matrix. Lattice, by default, is 'rect' and shape 'sheet'.
