Reconstruction Performance for Different Experimental Conditions. Comparison between LD (Laplace, design) and LR (Laplace, random experiments) under different conditions. Score is average iAUC after 25, ..., 50 experiments. (Left): Number r of non-zero u coefficients in each disturbance varied, keeping ||u|| constant. (Middle): Norm ||u|| of disturbances varied, while keeping r = 3 and low noise level. (Right): Stochastic noise in the data (1) varied, for constant ||u||, r = 3. Settings marked with *: LD is significantly superior to LR, according to t-test at level 1%.
