Meta-learning Based on Recurrent Neural Networks for Ensembling Forecasts of Time Series with Multiple Seasonal Patterns
摘要
This study explores meta-learning based on recurrent neural networks to combine forecasts generated by diverse models. While conventional forecast combination methods typically rely on basic averaging or linear regression, the application of machine learning opens the door to more advanced and efficient forecast aggregation via meta-learning. We define and evaluate different meta-learning scenarios tailored to time series with complex seasonality, leveraging the capabilities of modern recurrent neural networks to incorporate relevant information from recent time points. We specifically assess the performance of LSTM and GRU meta-learners, showcasing their superiority over conventional methods such as averaging and linear combination.
