QR Code Recognizer In .The e ect of the SOM training process is to cluster together similar patterns, while preserving the topology of input space After training, all that is given is the set of trained weights with no explicit cluster boundaries An additional step is required to nd these cluster boundaries One way to determine and visualize these cluster boundaries is to calculate the uni ed distance matrix (U-matrix) [403], which contains a geometrical approximation of the codebook vector distribution in the map The U-matrix expresses for each neuron, the distance to the neighboring codebook vectors Large values within the U-matrix indicate the position of cluster oundaries Using a gray-scale scheme, Figure 44(a) visualizes the U-matrix for the iris classi cation problem For the same problem, Figure 44(b) visualizes the clusters on the actual map Boundaries are usually found by using Ward clustering [23] of the codebook vectors Ward clustering follows a bottom-up approach where each neuron initially forms its own cluster At consecutive iterations, two clusters that are closest to one another are merged, until the optimal or speci ed number of clusters has been constructed The end result of Ward clustering is a set of clusters with a small variance over its members, and a large variance between separate clusters The Ward distance measure is used to decide which clusters should be merged The distance measure is de ned as drs = nr ns ||wr ws ||2 2 nr + ns (441).
