Detailed Description

An inner interface specifying an update function for a model.

The update function typically goes hand in hand with the type of model. For example, perceptron-style models get updated by adding to the current weight vector a possibly scaled version of the “gold” candidate hypothesis and subtracting a possibly scaled version of the candidate hypothesis that scored highest under the current model. Typically, implementations of this interface will be inner classes of the concrete Model implementation to which they apply.
