description |
Time series forecasting has attracted much attention due to its impact on many practical
applications. Neural networks (NNs) have been attracting widespread interest as
a promising tool for time series forecasting. The majority of NNs employ only autoregressive
(AR) inputs (i.e., lagged time series values) when forecasting time series.
Moving-average (MA) inputs (i.e., errors) however have not adequately considered.
The use of MA inputs, which can be done by feeding back forecasting errors as extra
network inputs, alongside AR inputs help to produce more accurate forecasts. Among
numerous existing NNs architectures, higher order neural networks (HONNs), which
have a single layer of learnable weights, were considered in this research work as they
have demonstrated an ability to deal with time series forecasting and have an simple
architecture. Based on two HONNs models, namely the feedforward ridge polynomial
neural network (RPNN) and the recurrent dynamic ridge polynomial neural network
(DRPNN), two recurrent error-based models were proposed. These models were
called the ridge polynomial neural network with error feedback (RPNN-EF) and the
ridge polynomial neural network with error-output feedbacks (RPNN-EOF). Extensive
simulations covering ten time series were performed. Besides RPNN and DRPNN, a
pi-sigma neural network and a Jordan pi-sigma neural network were used for comparison.
Simulation results showed that introducing error feedback to the models lead
to significant forecasting performance improvements. Furthermore, it was found that
the proposed models outperformed many state-of-the-art models. It was concluded
that the proposed models have the capability to efficiently forecast time series and that
practitioners could benefit from using these forecasting models. |
