Forecasting Crude Oil Price Using Kalman Filter Based on the Reconstruction of Modes of Decomposition Ensemble Model

Autor: Wei Gao, Muhammad Aamir, Ani Bin Shabri, Raimi Dewan, Adnan Aslam

Publikováno v: IEEE Access, Vol 7, Pp 149908-149925 (2019)

The modes' reconstruction into the stochastic and deterministic components is proposed for forecasting the crude oil prices with the concept of “divide and conquer” and modes reconstruction. It is to reduce the complexity in the computation and t
