class BayesClassifier

A multi class bayes classifier -- maximizes the likelihood of each class separately using a trainer for distribution.

Inheritance:

Public Fields

BayesClassifierMachine* bayesmachine

the bayes machine

int n_classes

the number of different classes

int** classes

all the example indices of each class

int* classes_n

the number of examples per class

Public Methods

BayesClassifier( BayesClassifierMachine* )

you need to define a BayesClassifierMachine to use this class

A multi class bayes classifier -- maximizes the likelihood of each class separately using a trainer for distribution. When testing, the predicted class corresponds to the trainer giving the maximum output, weighted by its prior probability.
