This group of researchers deal with a frequent problem in data processing of meteorological data series: the absence of data in several time intervals.
They recognize the usefulness of two traditional methods – Autoregressive Integrated Moving Average (ARIMA) and Regression Analysis (interpolation) – but also their limitations under particular conditions, and address the problem from a neural networks perspective, using 10 years of data from the UFPS weather station: 125658 records of temperature, radiation and energy, with 9.98% of missing data. Estimación de datos faltantes en series históricas de radiación global mediante algoritmos de redes neuronales abre la edición, el artículo reporta los resultados del trabajo realizado por un grupo de investigadores de la Universidad Francisco de Paula Santander (Cúcuta, Colombia), quienes abordan un problema recurrente en los datos de las series de tiempo meteorológicas: la falta de información (datos) en algunos intervalos de tiempo.
Los investigadores, luego de revisar las limitaciones que tienen en alg...
