LinearClassifier

abstract def copy(model: A, numClasses: Int): A

A function that creates a new classifier with numClasses set.

abstract def copy(model: A, w: RealVector): A

A function that creates a new linear model with parameters w.

abstract def lossGradStateless(model: A, w: RealVector, x: Features, y: Target): RealVector

A stateless function that calculates the gradient of the loss function wrt.
