| ) | const [pure virtual] |
Build a binary_threshold classifier.
Train classifier, returning weighted error Selects parameters of classifier which best separate examples from two classes, weighting examples appropriately when estimating the missclassification rate. Returns weighted sum of error, e.wts, where e_i =0 for correct classifications, e_i=1 for incorrect.
