Identification of transformer internal faults by using an RBF network based on dynamical principle component analysis
Ozgonenel, Okan; Kilic, Erdal; Thomas, David; Ozdemir, Ali Ekber (Ieee, 2007)In this paper; a method is proposed to detect and identify parameter faults in nonlinear dynamical systems. The approach is based on the principal component analysis (PCA) and artificial neural networks (ANNs) based on ... -
Reviewing and designing pre-processing units for RBF networks: initial structure identification and coarse-tuning of free parameters
Kayhan, Gokhan; Ozdemir, Ali Ekber; Eminoglu, Ilyas (Springer London Ltd, 2013)This paper reviews some frequently used methods to initialize an radial basis function (RBF) network and presents systematic design procedures for pre-processing unit(s) to initialize RBF network from available input-output ... -
A two-pass hybrid training algorithm for RBF networks
Ozdemir, Ali Ekber; Eminoglu, Ilyas (Ieee, 2013)This paper presents a systematic construction of linearly weighted Gaussian radial basis function (RBF) neural network. The proposed method is computationally a two-stage hybrid training algorithm. The first stage of the ...
