Please help me predict the CPC LABEL for this patentPATENT ABSTRACT: Some embodiments include a method of training an electronic transaction event classifier model to rank electronic transaction events. The method can include: receiving a training set of observable events corresponding to a set of quantifiable feature vectors, a set of known outcome labels, and a set of known cost values; setting initial parameters of a kernel function of a support vector machine; and iterating through potential weight vectors of the kernel function until the kernel function, as configured by a working weight vector of an iteration, is capable of estimating at least polarities of the known outcome labels within a threshold tolerance of accuracy based on the quantifiable feature vectors, wherein said iterating includes computing the working weight vector in a feature space of the quantifiable features in each iteration by solving variable constraints.
