如果你有每个折叠的混淆矩阵，你可以简单地将它们的值相加得到总混淆矩阵.

If you have the confusion matrices for each fold, you can simply sum their values to get the total confusion matrix.

例如，如果你有两个折叠，结果混淆矩阵是

For example, if you had two folds,and the resulting confusion matrices were

                     Classifier
                 -----------------
                 Class 1   Class 2
Actual | Class 1      25         3
       | Class 2       6        21

                     Classifier
                 -----------------
                 Class 1   Class 2
Actual | Class 1      23         5
       | Class 2       4        23

那么总混淆矩阵为

                     Classifier
                 -----------------
                 Class 1   Class 2
Actual | Class 1      48         8
       | Class 2      10        44
