i'm studying for PHD Entrance Exam on Stanford. one of previous material exam designed very challenging.
i want to design a NN for classifying following 2-class problem.
1) output should be -1 or 1.
2) output should be 0 or 1.
for sove this question i think using XOR neural network for following problem for above dataset? i'm not sure because one point under the X-axis in this picture and above data all is above X-axis? can anyone help me ?
i want to draw a NN for two case mentioned above and find minimum number of node (without input node). for example i think for 0 or 1 output we have following NN with (5 nodes and 2 input node)
