Kohonen self-organizing net

Consider a Kohonen self-organizing net with two cluster units and five input units. The weight vectors for the cluster units are given by

W1=[1.0 0.9 0.7 0.5 0.3]

W2=[0.3 0.5 0.7 0.9 1.0]

Use the square of the Euclidean distance to find the winning cluster unit for the input pattern x=[0.0 0.5 1.0 0.5 0.0].

Using a learning rate of 0.25,find the new weights for the wining unit.
