On the optimal selection of meteorological variables as inputs to machine learning models for solar irradiance forecasting
Variables output from numerical weather models are essential and widely used as inputs to machine learning models for forecasting the solar irradiance available at ground level. This abundance of data necessitates an effective optimization strategy to identify the most relevant features and eliminate those with limited impact in order to reduce computational resources.
