A novel hybrid approach to Baltic Dry Index forecasting based on a combined dynamic fluctuation network and artificial intelligence method
作者:
Highlights:
• A novel hybrid approach (DFN-AI) integrating complex network theory and AI algorithms is proposed to enhance the accuracy of the Baltic Dry Index (BDI) forecasting.
• DFN-AI models outperform their corresponding single AI forecasting models with lower absolute value, variance of errors, and also higher directional matching rates.
• The accuracy improvements of DFN-AI models are robust for different time-scale BDI datasets as well as in the respect of random sampling cases and challenging situations.
