Daily Crude Oil Price Forecasting Using Hybridizing Wavelet and Artificial Neural Network Model

Abstract EN

A new method based on integrating discrete wavelet transform and artificial neural networks (WANN) model for daily crude oil price forecasting is proposed.

The discrete Mallat wavelet transform is used to decompose the crude price series into one approximation series and some details series (DS).

The new series obtained by adding the effective one approximation series and DS component is then used as input into the ANN model to forecast crude oil price.

The relative performance of WANN model was compared to regular ANN model for crude oil forecasting at lead times of 1 day for two main crude oil price series, West Texas Intermediate (WTI) and Brent crude oil spot prices.

In both cases, WANN model was found to provide more accurate crude oil prices forecasts than individual ANN model.
