Illustration of the atoms learned with different values of η, placed at node 10 of the cimis graph. The more we penalize the quantization error, the more localized are the atoms. a η = 0.1; S = 1. b η = 0.1; S = 2. c η = 0.1; S = 3. d η = 10; S = 1. e η = 10; S = 2. f η = 10; S = 3. g η=∞; S = 1. h η=∞; S = 2. i η=∞; S = 3
