Java 问题理解weka apriori算法输出

我使用以下代码来查找有趣的关联规则
在文件

data.arff

上

我的问题是我不知道如何解释输出。 输出告诉我什么？ 我希望规则像[a=1，b=1]->[c=1]
举个例子，我没有得到

        //Define ArrayList to Add Clustered Information
        Apriori apriori = new Apriori();
        apriori.setNumRules(10);
        BufferedReader datafile = readDataFile("C:\\data.arff");
        Instances data = new Instances(datafile);
        apriori.buildAssociations(data);
        System.out.println("-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-");
        System.out.println("Number of Associations : " + apriori.getNumRules());
        System.out.println("Adding Association Information to ArrayList .."); 
        AssociationRules arules = apriori.getAssociationRules();
        int num = apriori.getAllTheRules().length;
        System.out.println("Num :" + num);

        for(AssociationRule ar : arules.getRules())
        {   
            System.out.println("premise: " + ar.getPremise());
            System.out.println("consequence: "+ar.getConsequence());

            System.out.println("---");
        }

data.arff

@relation Presence-Absence-Representation

@attribute a    {0,1}
@attribute b    {0,1}
@attribute c    {0,1}
@attribute d    {0,1}
@attribute e    {0,1}
@attribute f    {0,1}
@attribute g    {0,1}
@attribute h    {0,1}

@data
1,0,1,0,0,1,0,0
0,1,1,0,1,0,0,1
1,1,1,1,0,0,0,1
1,1,0,0,0,1,1,1
1,0,1,0,0,1,0,0
1,0,1,0,0,1,0,0
1,0,0,0,0,0,0,1
0,0,0,0,1,1,0,0
0,0,0,0,0,1,1,1

我得到以下输出：

-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-
Number of Associations : 10
Adding Association Information to ArrayList ..
Num :6
premise: [a=1]
consequence: [e=0]
---
premise: [b=0]

consequence: [d=0]

premise: [c=1]
consequence: [g=0]
---
premise: [a=1, d=0]
consequence: [e=0]

premise: [e=0, g=0]
