Homework #1. Find the output of the following 2-layer machine with inputs x, = 1.3, x2 =2, weightings w, = 0.7; W12 = 0.1; W21 = 1.2; Waz = 0.4. 1st (Input) 2nd (Output) O 2 #2. Find the output of the following 3-layer machine with inputs x, = 0.9, x2 = 2.1. Weightings from input to hidden layers, W1 = ( 5 0 4), and weightings from hidden to output layers W2 = (0.9 0.1) 0.4 0. 7), with outputs determined by the sigmoid function. 1st (Input) 2nd (Hidden) 3rd (Output) O
