<p>N = # of samples in validation dataset (200 in example),
M = # thresholds = # samples taken from the probability space (5 in example),
C = # classes in full dataset (3 in example)</p>
<p>Some invariants of the accuracy table:</p><ul>
<li><p>TP + FP + TN + FN = N for all thresholds for all classes</p></li>
<li><p>TP + FN is the same at all thresholds for any class</p></li>
<li><p>TN + FP is the same at all thresholds for any class</p><
