Figure 5.

Visualization of projected data onto a lower dimensional space (step 3 in Figure 3). The visualizations are scatter plots representing dimensionless scores of the projection of high-dimensional feature vectors onto the first (x-axis) against the second (y-axis) estimated components. (a) The data are from Task 1, which is the movement of finger taps. Triangles represent S_H, asterisks S_PD, and circles S_DBS. (b) The projections of PCA technique, (c) projections of Sammon's mapping, and (d) t-SNE map.
