LinearVectorClassifier

class LinearVectorClassifier[L <: DiscreteVar, F <: VectorVar] extends LinearMulticlassClassifier with VectorClassifier[L, F]

A VectorClassifier in which the score for each class is a dot-product between the observed feature vector and a vector of parameters. Examples include NaiveBayes, MultivariateLogisticRegression, LinearSVM, and many others. Counter-examples include KNearestNeighbor.
