The ROC curves obtained for the ICA-computed component, for the choices $\mathcal{V}$ = V (black), $\mathcal{I}$ (red) or $\mathcal{D}$ (blue); the data are those for 1 subject (AW) in the experiment. This is done for 36 cases: 2 components, 2 ICA algorithms (InfoMax or FastICA), 3 different time paradigms, 3 different overlap angles (θ = 100 is the independent case when $\mathcal{V}$ = $\mathcal{D}$). The comparison is with the ground truth activation patterns G₁ (1st component), G_2,θ (2nd component).
