Question 4 Marks: 20 (a) A single layer perceptron neural network is used to classify the 2 input logical gate NAND shown in figure Q4. Using as a learning rate of 0.1, train the neural network for the first 3 epochs. use a limiting function: 8(x) = flif y(1) > 0 lo other wise X-1 W=-0.4 W:=0.1 YO 9i) Output W,-0.5 [15 marks] (b) One basic component of Artificial Intelligence is Neural Networks, identify how neural networks are used in computer vision applications.
