Beyond wind speed: Integrating oceanic indices and time-lagged features for superior wind energy prediction
Fig 6
SHAP summary dot-plot for the three top MRMR-selected predictors (WIND, AMM_9, WIND_6).
Each point represents one forecast instance, plotted by its Shapley value (x–axis) to show the feature’s impact on the model’s output, and colored by the corresponding predictor value (blue = low, yellow = high). The current wind speed (WIND) dominates model behavior; higher WIND values consistently push predictions upward, while the nine-month Atlantic Meridional Mode index (AMM_9) and the six-month lagged wind (WIND_6) exert more moderate positive and negative influences, respectively.
