New Method of 1-D to 2-D Transformation of Time Series

EasyChair Preprint no. 3959

13 pagesDate: July 27, 2020


New method of 1-D to 2-D transformation of time series or one-dimensional signals was proposed. The method is based on a binary transformation of the time series. Resulting binary points are considered as interacting pseudo particles. The transformation is carried out using moving window. In each position of moving window, the pseudopotential is calculated and is written in the central point of moving window. Two pseudopotentials were considered: Ising spin-spin potential and Coulomb potential. Both potentials equally well describe the features of time series dynamics. Potential calculations were carried out at different values of the width of the sliding window. The resulting potential curves were grouped together to create 2-D images. This 1-D to 2_D transformation was compared with continues wavelet transform (CWT). The comparison showed that potential transformation gives more detailed information of hidden patterns then CWT.

Keyphrases: Binarization, clearing time series from outliers, continues wavelet transformation, Coulomb potential, Detrend, Ising potential, normalization, time series

BibTeX entry
BibTeX does not have the right entry for preprints. This is a hack for producing the correct reference:

  title = {New Method of 1-D to 2-D Transformation of Time Series},
  howpublished = {EasyChair Preprint no. 3959},

  year = {EasyChair, 2020}}
