  • Method for Classify .
  • Learn a probability distribution for each class to compute class probabilities.

Details & Suboptions

  • The "ClassDistribution" method learns a probability distribution for each class by applying LearnDistribution on the examples of this class. When given a new example to classify, the class probabilities of the example are computed by measuring the probability density function (PDF ) of the example for each class distribution. More precisely, the probabilities are computed using Bayes's theorem , where x is the example to classify, is the prior probability of the class, and is the PDF of x for the class distribution.
  • The following option can be given:
  • Method Automatic method to be used by LearnDistribution
  • In Method method, method can be any method of LearnDistribution , possibly with options and suboption specifications.
  • Classify [,AnomalyDetector Inherited] can be used to use the implicit mixture distribution learned by this method in order to detect an anomalous example.
