In the confusion matrix (from a segmentation output) given below:

a) Where do the numbers for the Predicted columns come from? (HINT: We all know it comes from the data. The question is: how do we predict them?)

b) what do the two circled numbers indicate? Please be SPECIFIC in your response to show that you understand the subject well.

\begin{tabular}{cccccc} \hline & Predicted 1 & Predicted 2 & Predicted 3 & Predicted 4 & Total \\ \hline Segment 1 & 8 & 1 & 3 & 0 & 12 \\ \hline Segment 2 & 1 & 13 & 0 & 0 & 14 \\ \hline Segment 3 & 2 & 2 & 4 & 0 & 8 \\ \hline Segment 4 & 3 & 3 & 0 & 0 & 6 \\ \hline Total & 14 & 19 & 7 & 0 & 40 \\ \hline \end{tabular}
