Understanding Confusion Matrix
A Confusion Matrix presents model predictions in a structured
format, typically organized into a matrix where rows represent
true classes and columns represent predicted classes. It comprises
four essential elements:
-
True Positive (TP): Correctly predicted
positive instances.
-
True Negative (TN): Correctly predicted
negative instances.
-
False Positive (FP): Incorrectly predicted
positive instances (Type I error).
-
False Negative (FN): Incorrectly predicted
negative instances (Type II error).
These elements enable the calculation of various performance
metrics crucial for evaluating model performance.
Components of a Confusion Matrix
-
True Positive (TP): Instances where the model
correctly predicts the positive class.
-
True Negative (TN): Instances where the model
correctly predicts the negative class.
-
False Positive (FP): Instances where the model
incorrectly predicts the positive class (Type I error).
-
False Negative (FN): Instances where the model
incorrectly predicts the negative class (Type II error).
