Bagging ensemble-based novel data generation method for univariate time series forecasting

作者:

Highlights:

• We propose a bagging based data generation method for univariate time series forecasting.

• We combine a wavelet transform with bootstrap for generating an ensemble model.

• The proposed method effectively enables univariate time-series data to the ensemble.

• The proposed method overcomes comparative prediction methods.

• The utility of the proposed method was proved through additional experiments.
