Consider the following network structure and the initial weights and bias a given. w1 = 0.3, W12 = 0.4, W21 = -0.3, W22 = 0.05, W3 = -0.5, WA = 0.2 and bias = 0. Given that < x1, x2, y >= < 1,0,0.5 >. x1 X2 W11 W12 W21 W22 W3 WA y (a) Compute the forward propagation and generate the output. Use Sigmoid activation function. (b) Compute the RMSE loss. (c) Let the given weights be at time (t-1). Compute the weights at time t using SGD. (d) Compute the weights at (t + 1) using Momentum. Assume a = 1.1 and = 0.8. 17
