Distribution of the $\lambda$ (a), difference in signal-to-noise ratio $\mathsf{\Delta }SNR$ (b) and root mean square error $RMSE$ (c) dataset average values obtained with the rejection ICA, wICA and the proposed method. For $\lambda$ and $\mathsf{\Delta }SNR$ the higher, while for $RMSE$, the lower values mean better performance.
