我一直在嘗試使用斯坦福Weka的MISVM。不過，我不斷收到錯誤無法處理數字屬性weka svm
@relation 'SpamDetectionTrainingSet'
@attribute 'checkin' real
@attribute 'tips' real
@attribute 'badges' real
@attribute 'friends' real
@attribute 'mayors' real
@attribute 'lists' real
@attribute 'target' {'spam','nonspam'}
@data
1165,36,1,1,4,47,nonspam
8521,492,620,7,74,144,nonspam
5408,189,306,0,27,121,nonspam
0,43,319,0,0,0,spam
我已經看到了前面的問題解決方案
weka.classifiers.mi.MISVM: Cannot handle numeric attributes!
我的訓練集文件（file.arff）。一個要點，我從他們觀察到的是保持名義上的target attribute。我的目標屬性是標稱只有
我的源代碼

public SVM()
{
try {
/* Loading the Data */
train = new DataSource("/home/hduser/file.arff");
trainData = train.getDataSet();
trainData.setClassIndex(trainData.numAttributes()-1);
/* Set Option for SVM Algorithm */
String[] opt = Utils.splitOptions("-N 1 -D");
/*Training */
weka.classifiers.mi.MISVM rf = new weka.classifiers.mi.MISVM();
rf.setOptions(opt);
System.out.println(rf.getFilterType());
rf.buildClassifier(trainData);

unknown = new DataSource("/home/hduser/fileTest1.arff");
unknownData = unknown.getDataSet();
unknownData.setClassIndex(unknownData.numAttributes()-1);
Instances copy = new Instances(unknownData);
for(int i=0;i<unknownData.numInstances();i++)

System.out.println("Hello ");
double value = rf.classifyInstance(unknownData.instance(i));
copy.instance(i).setClassValue(value);
}
DataSink.write("/home/hduser/output1.arff", copy);
}
catch (Exception e) {
