Class ClojureClassifier

java.lang.Object

weka.classifiers.AbstractClassifier

weka.classifiers.clojure.ClojureClassifier

All Implemented Interfaces:

Serializable, Cloneable, weka.classifiers.Classifier, weka.core.CapabilitiesHandler, weka.core.OptionHandler, weka.core.RevisionHandler

public class ClojureClassifier
extends weka.classifiers.AbstractClassifier
implements weka.core.OptionHandler, Serializable

A wrapper classifier for executing a classifier implemented in Clojure. The Clojure implementation is expected to have at least the following two functions:

learn-classifier [insts options-string]
distribution-for-instance [inst model]

The learn-classifier function takes an Instances object and an options string (which can be null). It is expected to return the learned model as some kind of serializable data structure. The distribution-for-instance function takes a Instance to be predicted and the model as arguments and returns the prediction as an array of doubles.

The Clojure implementation can optionally provide a model-to-string [model header] function to return a textual description of the model. See the weka-clj.simple classifier included in the source code of the clojureClassifier package

Valid options are:

 -N <namespace>
  Namespace of the Clojure classifier to use.
