ConfusionMatrix Properties

Threshold to be taken into account when determining the confusion matrix. If the threshold is modified, the whole matrix will be updated accordingly, so setting this property may be a costly action.

Access the results stored in the confusion matrix. The confusion matrix is to be read as follows: The first index (usually considered the line index) corresponds to the true class index, whereas the 2nd index (column index) is the prediction result. Example: Consider the result counts in a confusion matrix for a two-class problem to be distributed as follows: A B A 10 3 B 1 6 This means that 10 samples of class A have been correctly identified as class A, while 3 samples of class A have been misclassified as class B. Likewise, one sample of class B has been misclassified as class A, while 6 samples of class B have been identified correctly.

Number of classes in this matrix.
