Full Summary
Time-series forecasting often suffers from uncertainty and variability, making accurate predictions challenging. To address this, ensemble models combine predictions from multiple individual models, enhancing overall accuracy.
By applying information theory, the study identifies optimal ways to select and weight these models based on their predictive performance. The methodology involves evaluating various ensemble techniques, including weighted averages and stacking, to determine their effectiveness.
Results indicate that ensembles can reduce forecast error by up to 15% compared to single models. This improvement is particularly beneficial in fields like finance and supply chain management, where precise forecasts are critical.
The findings suggest that engineers and researchers should consider ensemble methods as a standard practice in time-series analysis.
