NAME
Algorithm::AdaBoost::Classifier
DESCRIPTION
This class should be instanciated via Algorithm::AdaBoost->train
.
METHODS
as_closure
Returns a CodeRef which delegates given arguments to classify
.
Altough you can use the object itself like a CodeRef because &{}
operator is overloaded with this method, it constructs a closure for each call. So if you classify many inputs, you should hold a closure explicitly or use classify
directly.
classify
Executes binary classification. Takes 1 argument as a feature and return a real number. If the number is positive, given feature is considered to belong to one class. Similary, If the number is negative, given feature is considered to belong to another one class. If zero is returned, it means that the feature cannot be classified (very rare case).
