Use weka SMOreg model

Demo Code

import weka.classifiers.Evaluation;
import weka.classifiers.functions.SMOreg;
import weka.core.Instances;
import weka.core.converters.ConverterUtils.DataSource;

public class SaveLoadModel {
    public static void main(String[] args) throws Exception {
        DataSource source = new DataSource("house.arff");
        Instances traindata = source.getDataSet();
        traindata.setClassIndex(traindata.numAttributes() - 1);

        SMOreg smo = new SMOreg();
        smo.buildClassifier(traindata);/*from   ww w  .j  a v a 2 s. c  o  m*/

        weka.core.SerializationHelper.write("smo.model", smo);

        SMOreg smo2 = (SMOreg) weka.core.SerializationHelper
                .read("smo.model");
        Evaluation evol = new Evaluation(traindata);
        evol.evaluateModel(smo2, traindata);
        System.out.println(evol.toSummaryString());

    }
