We want to train the network as below using the standard back propagation algorithm $($approximate steepest descent$).$ The following input and target are given as p$[1,1]$ t$=[0]$; The initial weights and biases are W$(0)=[1,-1],$ b$(0)=1$; Update the weights and bias after one backpropagation using alpha $=0\mathrm{.}1$
