2. Consider the sum of the squared errors cost function N KL J = 2 ΣΣ(imm - Ynm)². n=1 m=1 Compute the elements of the Hessian matrix J² J მ0 მ0]}, kj Near the optimum, show that the second order derivatives can be approximated by N KL მ2.J = ΣΣ дупт дупт n=1 m=1 kj In other words, the second-order derivatives can be a
