Abstract (en)

This research applies artificial intelligence techniques to predict physical variables such as irradiance and temperature, addressing the challenge of time series nonlinearity. The main objective is to compare the predictive performance of LSTM, GRU, and SGPR models across three datasets (Jena, Solcast, and IDEAM), evaluating threes liding-window configurations and an hourly prediction scheme, where a separate model is trained for each hour instead of relying on a single general model. Results, assessed using MAE, RMSE, and R², show that in the Jena dataset, for example, the SGPR model under the hourly approach achieves average values of 0.53◦C, 0.74◦C, and0.99, respectively. Overall, the findings suggest that employing multiple Gaussian process-based models trained with hour-specific information yields superior performance compared to using a single model.

Abstract (es)

Esta investigación aplica técnicas de inteligencia artificial para predecir variables físicas como irradiancia y temperatura, enfrentando el reto de la no linealidad en series de tiempo. El objetivo principal es comparar la eficiencia de modelos LSTM, GRU y SGPR en tres bases de datos (Jena, Solcast e IDEAM), evaluando tres configuraciones de ventanas deslizantes y un esquema de predicción horaria, en el cual se entrena un modelo independiente para cada hora en lugar de un único modelo general. Los resultados, medidos mediante MAE, RMSE y R², muestran que, en la base de datos Jena, por ejemplo, el modelo SGPR bajo el enfoque horario alcanza valores promedio de 0.53◦C, 0.74◦C y 0.99, respectivamente. En conjunto, los hallazgos sugieren que emplear múltiples modelos basados en procesos gaussianos con información específica por hora ofrece un desempeño superior al uso de un único modelo.
