Inputs. Each column in turn is changed to Output and a network is
created. The networks are trained for 2000 cycles. The Output is
paired with the most important Input. The strength of the association
is the importance of the most important input which is the sum of the
absolute weights of the connections from the input node to all the
nodes in the first hidden layer.
