Deep Analysis & Enterprise Applications
Select a topic to dive deeper, then explore the specific findings from the research, rebuilt as interactive, enterprise-focused modules.
The BWDformer model enhances runoff prediction through three key innovations: Wavelet Decomposition extracts multi-scale features; a Dynamic Feature Fusion (DFF) Module adaptively combines features; and Bayesian Optimization fine-tunes hyperparameters for optimal performance. This integrated approach addresses non-stationarity and improves prediction accuracy.
BWDformer consistently outperforms benchmark models (CNN, LSTM, Transformer, Informer) across four hydrological stations. It achieves significant reductions in MAE and RMSE, and improvements in R, NSE, and KGE, demonstrating superior prediction accuracy, robustness, and practicality in diverse hydrological environments.
While BWDformer achieves superior accuracy through complex integration, this comes with increased computational cost and parameters. Bayesian optimization, although increasing runtime, ensures optimal parameter configuration, trading efficiency for enhanced prediction performance and robustness. Future work will balance accuracy with efficiency.
