%description
Noise in the time-series data significantly affects the accuracy of the
Machine Learning (ML) models (Artificial Neural Network and Support Vector
Regression are considered here). Complete Ensemble Empirical Mode
Decomposition with Adaptive Noise (CEEMDAN) decomposes the time series
data into sub-series and help to improve the model performance. The models
can achieve higher prediction accuracy than the traditional ML models. Two
models have been provided here for time series forecasting. More
information may be obtained from Garai and Paul (2023)
<doi:10.1016/j.iswa.2023.200202>.
