(a) The ROC curve derived from the probabilistic outputs of the model showing the relation of true positive rates and false-positive rates for all thresholds values ∈ [0, 1]. Two curves are shown for both the SF ≥ C1 and SF ≥ M2 cases. The dashed line denotes the random classifier behaviour. (b) Evolution of the TSS score for the same range of applied thresholds. Red circles mark the points for a threshold equal to 0.5.
