3) Consider the Bidirectional Associative Memory Neural Network that described by the following set of differential equations : u(t)=Au(t)+Wg(z(t))+Iz(t)=Bz(t)+Vg(u(t))+J a) Define the equilibrium equation for this neural network model. (10 p.) b) Shift the equilibrium point of the neural network system to the origin. ( 20p.)
