2. Given initial network defined as a logical AND function learning perceptron and that it accepts two input X1, with initial weight, wi=0.2 and input X2 with weight input w2=0.4. Let the learning rate be n =0.2, the threshold is specified as a third weight, w3=0.3 with a constant input value X3 = -1. i. Draw the diagram of the initial unlearned network [41 ii. With the aid of a well labeled table, show how the weights change as the network learns. [12] iii. Draw the diagram of the final leaned network. [4]
