Consider the two-layer network shown in the next figure. The initial weights and biases are set to w' = 1, b' = 1, w? = -2, b = 1 An input/target pair is given to be (p = 1),(t = 1)). i. Find the squared error (e)? as an explicit function of all weights and biases. ii. Using part (i), find a(e)?/ow' at the initial weights and biases. iii. Repeat part (ii) using backpropagation and compare results
