Problem 2. In the class you have been shown with a code to solve the XOR problem using soft bipolar activation function (signals are in the range of (-1,+1)). The MATLAB code in the lecture slides can be downloaded from Canvas (ebp.m). 1) Please modify the code and solve the XOR problem for unipolar case (signals are in the range of (0,+1). [0 0] ==> 0 [01] ==> 1 [10] ==> 1 [1 1] ==> 0 2) Please modify the code to solve the Parity-4 problem. For both 1) and 2), you need to use a multi-layer neural network. Include your Matlab code to show what you do. HINT: Before completing you homework, try to experiment with different values of learning constant and various neuron gains. So you can receive the required solution to the error 0 [01] ==> 1 [10] ==> 1 [1 1] ==> 0 2) Please modify the code to solve the Parity-4 problem.
