Özet
A Neural Architecture Search-enhanced Dual Stage Attention Bidirectional Long Short-Term Memory (NAS-DSA-BiLSTM) model is proposed to capture nonlinear temporal hydrological patterns and is evaluated at three hydrological stations. The NAS-enhanced model achieved the best performance at Kaptanpasa, with the lowest MSE (11.249-16.224) and the highest R2 values, outperforming LSTM and DNN-LSTM models. Additional evaluations using NSE, sensitivity analysis, and Taylor diagrams confirmed stable and accurate predictions, particularly at Ulucami (NSE = 0.91) and Kaptanpasa (NSE = 0.80), demonstrating the model's robustness for streamflow forecasting. The proposed model improved MSE by 15-26%, demonstrating robust and reliable streamflow forecasting performance.
