ROC statistics depicting the mean and std. deviations of TPR and FPR for 10 random noise frames generated for each combination of signal and noise: (a) Signal level = 1%; (b) Signal level = 3%. Clearly, w-ICA shows superior statistics for all combinations except lower TPR for 1% signal and higher levels of noise.
