That's a good question, @IsmaelAh !!

The short answer is 0. zero is a good starter threshold value.

The long answer is a little bit complicated. First, we have to split the data into three sets: training set, validation set, and test set. Then we try different values for the threshold and choose the one that maximizes the validation set.
