Sketch derivation of dual form The Representer Theorem states that the solution w can always be written as a linear combination of the training data: w = XN j=1 Webbrelationship to the original, primal, problem. 4.1 Basic Duality The study of duality is very important in LP. Knowledge of duality allows one to develop increased insight into LP solution interpretation. Also, when solving the dual of any problem, one simultaneously solves the primal. Thus, duality is an alternative way of solving LP problems.
