Confusion Matrix
What is a confusion matrix?
Answer
A confusion matrix is the following (self-explanatory):
\[
\begin{array}{c|cc}
& \text{Predicted Positive (1)} & \text{Predicted Negative (0)} \\
\hline
\text{Actual Positive (1)} & TP & FN \\
\text{Actual Negative (0)} & FP & TN \\
\end{array}
\]
