title: 'SVMD: Spearman Variational Mode Decomposition'
version: 0.1.0
doi: 10.32614/CRAN.package.SVMD
abstract: In practice, it is difficult to determine the number of decomposition modes,
  K, for Variational Mode Decomposition (VMD). To overcome this issue, this study
  offers Spearman Variational Mode Decomposition (SVMD), a method that uses the Spearman
  correlation coefficient to calculate the ideal mode number. Unlike the Pearson correlation
  coefficient, which only returns a perfect value when X and Y are linearly connected,
  the Spearman correlation can be calculated without knowing the probability distributions
  of X and Y. The Spearman correlation coefficient, also called Spearman's rank correlation
  coefficient, is a subset of a wider correlation coefficient. As VMD decomposes a
  signal, the Spearman correlation coefficient between the reconstructed and original
  sequences rises as the mode number K increases. Once the signal has been fully decomposed,
  subsequent increases in K cause the correlation to gradually level off. When the
  correlation reaches a specific level, VMD is said to have adequately decomposed
  the signal. Numerous experiments revealed that a threshold of 0.997 produces the
  best denoising effect, so the threshold is set at 0.997. This package has been developed
  using concept of Yang et al. (2021)<https://doi.org/10.1016/j.aej.2021.01.055>.
