  • Evolutionaty training for dynamical recurrent neural networks: an application in finantial time series prediction 

    Delgado Calvo-Flores, Miguel; Pegalajar Jiménez, Mª Carmen; Pegalajar Cuéllar, Manuel (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 2006)
    Article
    Open Access
    Theoretical and experimental studies have shown that traditional training algorithms for Dynamical Recurrent Neural Networks may suffer of local optima solutions, due to the error propagation across the recurrence. In the ...
  • Fuzzy Grammatical Inference Using Neural Network 

    Blanco Morón, Armando; Delgado, A.; Pegalajar Jiménez, Mª Carmen (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1998)
    Article
    Open Access
    We have shown a model of fuzzy neural network that is able to infer the relations associated to the transitions of a fuzzy automaton from a fuzzy examples set. Neural network is trainned by a backpropagation of error based ...
