Show that, regardless of the dimensionality of the feature vectors, a data set that has just two data points, one from each class, is sufficient to determine the location of the maximum-margin hyperplane. Hint #1: Consider a data set of two data points, X1 E C (y1 = +1) and X2 C2 (y2 = -1) and set up the minimization problem (for computing the hyperplane) with appropriate constraints on w'x+b and w'xg+b and solve it. Hint #2: This can be formed as a constrained optimization problem. arg min ||w| Subject to: (some constraint) What is w? b? Hint: What are the constraints? How did we solve the constrained optimization problem in Fisher's linear discriminate (see Linear Models Lecture Notes or constrained optimization from Calculus)?
