Sensitivity analysis of parameter K and in VMD.

(A) Influence of K on the VMD performance. (B) Influence of on the VMD performance. X-axis represents the value of K or , left Y-axis represents spectral kurtosis, right Y-axis represents KL divergence. The parameters K and have significant and coupled impacts on decomposition performance.
