## weka.classifiers.mi
Class MILR

    java.lang.Object
      weka.classifiers.Classifier
          weka.classifiers.mi.MILR

All Implemented Interfaces:
  java.io.Serializable, java.lang.Cloneable, CapabilitiesHandler, MultiInstanceCapabilitiesHandler, OptionHandler, RevisionHandler

    public class MILR

extends Classifier
implements OptionHandler, MultiInstanceCapabilitiesHandler

Uses either standard or collective multi-instance assumption, but within linear regression. For the collective assumption, it offers arithmetic or geometric mean for the posteriors.

Valid options are:

     -D
      Turn on debugging output.

     -R <ridge>
      Set the ridge in the log-likelihood.

     -A [0|1|2]
      Defines the type of algorithm:
       0. standard MI assumption
       1. collective MI assumption, arithmetic mean for posteriors
       2. collective MI assumption, geometric mean for posteriors
