Optimization example. We tested our clustering approach on synthetic data with linear and non-linear boundaries to predict the validity of the results on real data. This example shows the determination of KSC's optimal parameters σ and k for the solution of a problem with samples distributed into three concentric circles. Each combination of σ and k produces a compactness value. The solution is selected from the set of parameters which produced the minimum value of compactness (marked by the blue box)
