Fig. 6

Visualization of projected data onto a lower dimensional space. Separation of groups by the use of the Sammon’s projection method. The visualizations are scatter plots representing dimensionless scores of the nonlinear projection of high-dimensional feature vectors (FS-IA) onto the first (x axis) against the second (y axis) estimated components. Triangles represent SDBS, circles SH and asterisks SPD. a represents Task 1, b Task 2, c Task 3 and d Task 4
