Abstract:
1. A computer-readable storage medium storing a set of instructions for building a support vector classifier useful for classifying a plurality of documents, including textual documents, the set of instructions being executed by a processor, the set of instructions performing the steps of: selecting a plurality of training documents, each training document having suitable numeric attributes which are associated with a training document vector; initializing a classifier weight (w) and a classifier intercept (b) for a classifier boundary, the classifier boundary separating at least two document classes; determining which training document vectors arc suitable support vectors; re-computing the classifier weight vector and the classifier intercept for the classifier boundary using the suitable support vectors together with an iteratively reindexed least squares method and a conjugate gradient method with a stopping criterion; and storing the recomputed classifier weight vector and the classifier intercept for the classifier boundary at a data store in communication with the processor.
