To overcome this issue, this study offers Spearman\nVariational Mode Decomposition (SVMD), a method that uses the\nSpearman correlation coefficient to calculate the ideal mode\nnumber. Unlike the Pearson correlation coefficient, which only\nreturns a perfect value when X and Y are linearly connected,\nthe Spearman correlation can be calculated without knowing the\nprobability distributions of X and Y. The Spearman correlation\ncoefficient, also called Spearman's rank correlation\ncoefficient, is a subset of a wider correlation coefficient. As\nVMD decomposes a signal, the Spearman correlation coefficient\nbetween the reconstructed and original sequences rises as the\nmode number K increases. Once the signal has been fully\ndecomposed, subsequent increases in K cause the correlation to\ngradually level off. When the correlation reaches a specific\nlevel, VMD is said to have adequately decomposed the signal.\nNumerous experiments revealed that a threshold of 0.997\nproduces the best denoising effect, so the threshold is set at\n0.997. This package has been developed using concept of Yang et\nal.
