Unformatted text preview: • 1 st iteration : the neighborhood size is set to 1, i.e., h j,i ( x ) of the winning neuron and the two neurons (one at each side) immediately next to it equals to 1. It is zero for all other neurons. • 2 nd iteration : the neighborhood size is reduced to 0, i.e., h j,i ( x ) of the winning neuron is 1 while it is zero for all other neurons. Remark : The neighborhood relationship is NOT cyclic. This means that if the winning neuron is at the end of the 1-D SOM, only one side of neighborhood is considered. w 44 w 14 w 34 x 4 x 3 x 2 x 1 w 41 w 21 w 11 y 1 y 2 1 y 3 2 3 y 4 4...
