Density-based Adaptive Mode Decomposition

Variational Mode Decomposition (VMD) requires manual specification of mode numbers and center frequencies, limiting its practical applicability for non-stationary signals. This paper introduces Density-based Adaptive Mode Decomposition (DAMD), which addresses these limitations through three key innovations. First, we establish mathematical equivalence between VMD optimization and density-based clustering, enabling automatic mode detection through meanshift clustering with adaptive bandwidth esti
