Example of our adaptation of the normalized confusion matrix to show classification performance for detailed ball contact labels (bcs). $P_{c,b}$ denotes predictions of class c of instances of the true ball contact b. For orientation, we give the true class on the bottom. Light color represents low values, dark color represents high values. For an optimal classifier $P_{A,1}$, $P_{A,2}$, $P_{B,3}$ and $P_{C,4}$ are one and all other cells contain zeros.
