Journal ArticleDOI
Soft-computing techniques and ARMA model for time series prediction
Ignacio Rojas,Olga Valenzuela,Fernando Rojas,Alberto Guillén,Luis Javier Herrera,Héctor Pomares,Lozano Marquez,Miguel Pasadas +7 more
TL;DR: A new procedure to predict time series using paradigms such as: fuzzy systems, neural networks and evolutionary algorithms, so that the linear model can be identified automatically, without the need of human expert participation is presented.
Journal ArticleDOI
Hybridization of intelligent techniques and ARIMA models for time series prediction
Olga Valenzuela,Ignacio Rojas,Fernando Rojas,Héctor Pomares,Luis Javier Herrera,Alberto Guillén,Lozano Marquez,Miguel Pasadas +7 more
TL;DR: This paper proposes a hybridization of intelligent techniques such as ANNs, fuzzy systems and evolutionary algorithms, so that the final hybrid ARIMA-ANN model could outperform the prediction accuracy of those models when used separately.
Journal ArticleDOI
Recursive prediction for long term time series forecasting using advanced models
Luis Javier Herrera,Héctor Pomares,Ignacio Rojas,Alberto Guillén,Alberto Prieto,Olga Valenzuela +5 more
TL;DR: This paper presents the utility of two different methodologies, the TaSe fuzzy TSK model and the least-squares SVMs, to solve the problem of long term time series prediction using recursive prediction.
Journal ArticleDOI
Combination of heterogeneous eeg feature extraction methods and stacked sequential learning for sleep stage classification
Luis Javier Herrera,Carlos M. Fernandes,Carlos M. Fernandes,Antonio M. Mora,Daria Migotina,Rogerio Largo,Alberto Guillén,Agostinho Rosa +7 more
TL;DR: Two main approaches are proposed: the combination of features extracted from electroencephalogram (EEG) signal by different extraction methods, and the use of stacked sequential learning to incorporate predicted information from nearby sleep stages in the final classifier.
Journal ArticleDOI
Yield development in potatoes as influenced by cultivar and the timing and level of nitrogen fertilization
TL;DR: Path-coefficient analysis based on an ontogenetic model was used to study the relationships between tuber yield and yield components as influenced by cultivar and nitrogen fertilization, finding that compensatory mechanisms during the formation of the three yield components in the potato resulted stronger in the N experiments.
