The confusion matrix shows the ways in which your classification model is confused when it makes predictions. It is a table with 4 different combinations of predicted and actual values.
True Positive, True Negative, False Positive, False Negative
- “true positive” for correctly predicted event values.
- “false positive” for incorrectly predicted event values.
- “true negative” for correctly predicted no-event values.
- “false negative” for incorrectly predicted no-event values.
Type of errors
TypeI:- The model has predicted Yes, but the actual value was No. It is called False Positive.
TypeII:- The model has predicted no, but the actual value was Yes, it is also called a False Negative.
