Abstract: |
This study presents a multiple-input multiple-output (MIMO) approach for
multi-step-ahead time series prediction with a Gaussian process regression
(GPR) model. We assess the forecasting performance of the GPR model with
respect to several neural network architectures. The MIMO setting allows
modelling the cross-correlations between all regions simultaneously. We find
that the radial basis function (RBF) network outperforms the GPR model,
especially for long-term forecast horizons. As the memory of the models
increases, the forecasting performance of the GPR improves, suggesting the
convenience of designing a model selection criteria in order to estimate the
optimal number of lags used for concatenation. |
