The figure below shows a simple neural network. An observation with two variables (5,?) is presented to the network as shown. What is the updated weight if linear function y=x is used as the activation function and the Mean Squared Error as the error function? Mean Squared Error = (y -- j") 2 True Output 1 O (0.91, 0.83) O (0.5, 1.4) O (4.15, 5.87) O (0.81,1.01)
