The effect of various model norms on the model from a synthetic given dataset. Norms with a smooth amplitude constraint, represented by [2,2,2,2], [2,1,1,1], and [2,0,0,0], are shown in the top row (a–c). Models with a moderate amplitude constraint, such as [1,2,2,2], [1,1,1], and [1,0,0,0], are displayed in the middle row (d–f). And the models [0,2,2,2], [0,1,1,1], and [0,0,0,0] are displayed in the bottom row (g–i) of models with a compact amplitude constraint. The true model is illustrated in panel (j)
