Package
weka.classifiers.meta
Synopsis
A metaclassifier for handling multi-class datasets with 2-class classifiers. This classifier is also capable of applying error correcting output codes for increased accuracy.
Options
The table below describes the options available for MultiClassClassifier.
Option | Description |
---|---|
classifier | The base classifier to be used. |
debug | If set to true, classifier may output additional info to the console. |
method | Sets the method to use for transforming the multi-class problem into several 2-class ones. |
randomWidthFactor | Sets the width multiplier when using random codes. The number of codes generated will be thus number multiplied by the number of classes. |
seed | The random number seed to be used. |
usePairwiseCoupling | Use pairwise coupling (only has an effect for 1-against-1). |
