我了解混淆矩阵的构造，以及如果更改了类，则条目的作用.

I have understood the construction of confusion matrices and the role of the entries if the class is changed.

使用以下方法获得的0类的混淆矩阵

The confusion matrices for the class 0 obtained using

caret::confusionMatrix(table(max.col(probabilities) - 1,Test_Set$Species), positive = '0')

以及使用

caret::confusionMatrix(table(max.col(probabilities) - 1,Test_Set$Species), positive = '1')

和

对于第0类，tp = 36，tn = 13，fp = 1，fn = 0，对于第1类:tp = 13，tn = 36，fp = 0，fn = 1(角色tp和tn的值，以及fp和fn的值被切换).

In case of class 0: tp = 36, tn = 13, fp = 1, fn = 0, and in case of class 1: tp = 13, tn = 36, fp = 0, fn = 1 (the roles of tp and tn, and that of fp and fn are switched).
