As AJNeufeld's answer mentioned, the test case getTargetString("Where the start is before here.", "start", "here"); will return "". I am going to fix this with the vocabulary word comparison tec...
I have the following code for determining TP, TN, FP and FN values for binary classification given two sparse vectors as input (using the sparse library):
def confused(sys1, ann1):
# True Positive (TP): we predict a label of 1 (positive), and the true label is 1.
TP = np.sum(np.logical_an...
