如何在eclipse java中重用从explorer(在weka中)创建的已保存分类器

Mr_*_*Hmp 7 java artificial-intelligence machine-learning weka

我在WEKA中创建了一个分类器,我将它保存在我的硬盘上,现在我想在eclipse中使用weka api来使用该分类器.

我怎样才能做到这一点?请指导我...谢谢

以下是加载模型以预测实例值的示例.示例模型是在Weka Explorer中创建并保存的J48决策树.它是根据Weka提供的名义天气数据建造的.它被称为"tree.model".

 //load model
String rootPath="/some/where/"; 
Classifier cls = (Classifier) weka.core.SerializationHelper.read(rootPath+"tree.model");

//predict instance class values
Instances originalTrain= //load or create Instances to predict

//which instance to predict class value
int s1=0;  

//perform your prediction
double value=cls.classifyInstance(originalTrain.instance(s1));

//get the name of the class value
String prediction=originalTrain.classAttribute().value((int)value); 

System.out.println("The predicted value of instance "+
                    Integer.toString(s1)+
                    ": "+prediction);

这个输出是:

The predicted value of instance 0: no
