8- Consider a neural network shown in the following figure: Assume all neurons have sigmoid activation functions and a bias which is equal to 0. After training the neural network, the following weight vector s are obtained: v1=[0.50.3]v2=112w1=[0.20.8]w2=2 Determine neurons' outputs 1,y2 and z1, if the input to the network is x=[1;0;2]
