Supplementary material: - Swissroll_NoiseX10_rbf30.gif: GIF animation of the pDRUR with the 3D Swiss roll of fig. 7 (first 100 iterations). - Swissroll3D_NoiseX10_rbf30.gif: flyby around the 3D Swiss roll of fig. 7 for the initial and final iterations. - digit7_X.gif: GIF animation of the X in latent space of fig. 9 (first 200 iterations). - digit7.gif: 6160x2520 GIF image containing, as a grid of 220x90, all the 28x28 MNIST digits '7' and their rotated versions; this was the input to pDRUR. You may need to zoom in to see the detailed images. - digit78_X.gif: like digit7_X.gif but for a dataset containing rotations of 10 digits '7' (outside loops) and 10 digits '8' (inside loops); initial X from PCA. - digit7_fx.gif: reconstruction of an out-of-sample sequence similar to the one in fig. 9 (right plot). All these images and videos may be seen with a web browser or with specialized GIF image viewers.
