The most important limitation of th

The most important limitation of the proposed VMD is
with boundary effects, and sudden signal onset in general.
This is strongly related to the use of an L2-based smoothness
term, that overly penalizes jumps at the domain borders and
within; conversely, this is also reflected by implicit periodicity
assumptions when optimizing in Fourier domain, and by the
narrow-band violation caused by discontinuous envelopes in
such AM-FM signals. Another point that critics might high-
light, is the required explicit (manual) selection of the number
of active modes in the decomposition, like in EWT but as
opposed to EMD. Current work addresses these shortcomings,
and we are also working on suitable extensions to signals on
domains of dimension greater than one.

拟议的 VMD 最重要的限制是边界效应与一般信号突然发病。这是强烈有关使用基于 L2 的平滑度术语，过度惩罚跳跃在域边界和内;相反，这也反映在的隐式的周期性假设当优化傅里叶域中和通过窄带违反造成的不连续的信封在这样的调幅-调频信号。另一个点，批评家可能会高光，是数的需要显式 (手动) 选择主动模式的分解，喜欢在东环但作为反对 EMD。当前工作解决这些缺点，而且我们也正在对信号的适当扩展域的尺寸大于一。
