List of forwardSelect() Examples

Examples of forwardSelect()

weka.classifiers.meta.ensembleSelection.ModelBag.forwardSelect()
Forward select one model. Will add the model which has the best effect on performance. If replacement is false, and all models are chosen, no action is taken. If a model can be added, one always is (even if it hurts performance). @param withReplacement whether a model can be added more than once. @param instances The dataset, for calculating performance. @param metric The metric to which we will optimize. See EnsembleMetricHelper @throws Exception if something goes wrong
