    • A Hybrid Algorithm for Missing Data Imputation and Its Application to Electrical Data Loggers 

      Crespo Turrado, Concepción; Sánchez Lasheras, Fernando; Calvo-Rolle, José Luis; Piñón-Pazos, A.; Melero, Manuel G.; Cos Juez, Francisco Javier de (Multidisciplinary Digital Publishing Institute, 2016)
      The storage of data is a key process in the study of electrical power networks related to the search for harmonics and the finding of a lack of balance among phases. The presence of missing data of any of the main electrical ...

    • A New Missing Data Imputation Algorithm Applied to Electrical Data Loggers 

      Crespo Turrado, Concepción; Sánchez Lasheras, Fernando; Calvo-Rolle, José Luis; Piñón-Pazos, A.; Cos Juez, Francisco Javier de (Multidisciplinary Digital Publishing Institute, 2015)
      Nowadays, data collection is a key process in the study of electrical power networks when searching for harmonics and a lack of balance among phases. In this context, the lack of data of any of the main electrical variables ...

    • Comparative study of imputation algorithms applied to the prediction of student performance 

      Crespo Turrado, Concepción; Casteleiro-Roca, José-Luis; Sánchez Lasheras, Fernando; López-Vázquez, José-Antonio; De Cos Juez, Francisco Javier; Pérez Castelo, Francisco Javier; Calvo-Rolle, José Luis; Corchado, Emilio (Oxford University Press, 2019-12-27)
      [Abstract]: Student performance and its evaluation remain a serious challenge for education systems. Frequently, the recording and processing of students’ scores in a specific curriculum have several f laws for various ...

    • Missing data imputation of solar radiation data under different atmospheric conditions 

      Crespo Turrado, Concepción; Meizoso-López, María-Carmen; Sánchez Lasheras, Fernando; Rodríguez Gómez, Benigno Antonio; Calvo-Rolle, José Luis; Cos Juez, Francisco Javier de (MDPI, 2014-10-29)
      [Abstract] Global solar broadband irradiance on a planar surface is measured at weather stations by pyranometers. In the case of the present research, solar radiation values from nine meteorological stations of the ...
