Investigating the accuracy of cross-learning time series forecasting methods
The M4 competition identified innovative forecasting methods, advancing the theory and
practice of forecasting. One of the most promising innovations of M4 was the utilization of
cross-learning approaches that allow models to learn from multiple series how to accurately
predict individual ones. In this paper, we investigate the potential of cross-learning by
developing various neural network models that adopt such an approach, and we compare
their accuracy to that of traditional models that are trained in a series-by-series fashion. Our …
