Sequential Minimal Optimization: A Fast Algorithm for ...
3 where xi is the ith training example, and yi is the correct output of the SVM for the ith training example. The value yi is +1 for the positive examples in a class and –1 for the negative examples. Using a Lagrangian, this optimization problem can be converted into a dual form which is a QP problem where the objective function Ψ is solely dependent on a set of Lagrange multipliers αi,
