Enhancing Missing Data Imputation of Non-stationary Signals with Harmonic Decomposition

1 code implementation8 Sep 2023 Joaquin Ruiz, Hau-Tieng Wu, Marcelo A. Colominas

In this paper, we introduce a novel algorithm, coined Harmonic Level Interpolation (HaLI), which enhances the performance of existing imputation algorithms for oscillatory time series.
