Abstract
There are disclosed devices, system and methods for determining a performance score for a trained binary signal classifier (classifier) by determining test output predictions for test input data entries that are input into the classifier. The test outputs are then compared to known outputs of each of the input data entries to determine whether each test output is a true negative (TN), true positive (TP), false negative (FN) or false positive (FP). A number of correct test outputs (R) is defined as a number of the true negative outputs (TN) plus a number of the true positive outputs (TP). A number of incorrect test outputs (W) is defined as a number of the false negative outputs (FN) plus a number of the false positive outputs (FP). The performance score is then calculated using a mathematical expression that decreases as W increases, decreases as TN decreases and decreases as TP decreases.
