We have two classes represented by two features: X1 and X2. The positive samples have the following format: (X1,X2). Class 1: (4,2)(5,7)(6,5)(6,9)(8,4)(10,4) Class 2: (3,5)(5,4)(7,7)(8,9)(9,6)(10,8)(11,7) The questions are: a. Obtain the mathematical formulation of the border between both classes using the Bayes Classifier. b. Obtain the line that separates both classes in the case of 1-nearest neighbor
