general, functional data contains both phase (or x or horizontal) and amplitude (or y or vertical) variability. Traditional … technique called elastic shape analysis of curves that involves a new mathematical representation of functional data. Then … that ignore phase-amplitude separation. Furthermore, the generative models are applied to classification of functional data …
