Figure 8
The spectral error [defined in equation (5)[link]] associated with each of the discussed algorithms: random raster sampling, data-driven raster sampling (RISS) and data-driven CUR raster sampling (CURISS). The experimental set-up is the same as in Fig. 7[link]. We provide a close-up of the results for subsampling ratios less than 10% in Fig. 9[link].
