List of pctCorrect() Examples

Examples of pctCorrect()

weka.classifiers.Evaluation.pctCorrect()
Gets the percentage of instances correctly classified (that is, for which a correct prediction was made). @return the percent of correctly classified instances (between 0 and 100)

Examples of weka.classifiers.Evaluation.pctCorrect()


                                eval.crossValidateModel(cpyCls1, randData, folds, rand);   // actual randomization happens here
                                cpyCls2.buildClassifier(randData);


                                avgRoc += eval.weightedAreaUnderROC();
                                avgAcc += eval.pctCorrect();
