java.lang.Objectweka.classifiers.Classifier
weka.classifiers.functions.PLSClassifier
public class PLSClassifier
A wrapper classifier for the PLSFilter, utilizing the PLSFilter's ability to perform predictions.
Valid options are:-filter <filter specification> The PLS filter to use. Full classname of filter to include, followed by scheme options. (default: weka.filters.supervised.attribute.PLSFilter)
-D If set, classifier is run in debug mode and may output additional info to the console
Options specific to filter weka.filters.supervised.attribute.PLSFilter ('-filter'):
-D Turns on output of debugging information.
-C <num> The number of components to compute. (default: 20)
-U Updates the class attribute as well. (default: off)
-M Turns replacing of missing values on. (default: off)
-A <SIMPLS|PLS1> The algorithm to use. (default: PLS1)
-P <none|center|standardize> The type of preprocessing that is applied to the data. (default: center)
