List of classifyInstance() Examples

Examples of classifyInstance()

org.mitre.jcarafe.jarafe.JarafeMEDecoder.classifyInstance()
weka.classifiers.Classifier.classifyInstance()
Classifies the given test instance. The instance has to belong to a dataset when it's being classified. Note that a classifier MUST implement either this or distributionForInstance(). @param instance the instance to be classified @return the predicted most likely class for the instance or Instance.missingValue() if no prediction is made @exception Exception if an error occurred during the prediction
weka.classifiers.meta.FilteredClassifier.classifyInstance()
weka.classifiers.trees.J48.classifyInstance()
Classifies an instance. @param instance the instance to classify @return the classification for the instance @throws Exception if instance can't be classified successfully
