Synopsis#

Class for running an arbitrary classifier on data that has been passed through an arbitrary filter. Like the classifier, the structure of the filter is based exclusively on the training data and test instances will be processed by the filter without changing their structure.

If unequal instance weights or attribute weights are present, and the filter or the classifier are unable to deal with them, the instances and/or attributes are resampled with replacement based on the weights before they are passed to the filter or the classifier (as appropriate).

Options#

• -F <filter specification>

  Full class name of filter to use, followed by filter options. default: "weka.filters.supervised.attribute.Discretize -R first-last -precision 6"

• -doNotCheckForModifiedClassAttribute

  If set, classifier will not check whether the filter modifies the class (use with caution).

• -S <num>

  Random number seed. (default 1)

• -W <classifier name>

  Full name of base classifier. (default: meka.classifiers.multitarget.CC)

• -output-debug-info

  If set, classifier is run in debug mode and may output additional info to the console

• -do-not-check-capabilities

  If set, classifier capabilities are not checked before classifier is built (use with caution).

• -num-decimal-places

  The number of decimal places for the output of numbers in the model (default 2).

• -batch-size

  The desired batch size for batch prediction (default 100).

Options specific to classifier meka.classifiers.multitarget.CC:

• -S <value>

  The seed value for randomizing the data. (default: 0)

• -W <classifier name>

  Full name of base classifier. (default: weka.classifiers.trees.J48)

• -output-debug-info

  If set, classifier is run in debug mode and may output additional info to the console

• -do-not-check-capabilities

  If set, classifier capabilities are not checked before classifier is built (use with caution).

• -num-decimal-places
