grnns can be designed very quickly. net = newgrnn(P,T,spread) takes three inputs, P R-by-Q matrix of Q input vectors T S-by-Q matrix of Q target class vectors spread Spread of radial basis functions (default =
Based on this, a carefully-designed generalized regression neural network (GRNN) with a limited number of parameters is hierarchically trained by the feature vectors from samples in the training IQA data set. Comprehensive experimental evaluations on the hyperspectral IQA images from the DOTA dataset ...
Generalized regression neural networks (GRNNs) [6], a variant of radial basis function networks [7], exhibit interesting properties to develop a fast forecasting tool: 1) they have a single-pass learning, 2) they only need to set or fit one parameter and 3) they produce deterministic result...

neural network put forward by SCHUH et al [9] has the problem of low efficiency, being sensitive to the initial values and non-unique solutions. In this work, we propose to use a highly efficient ANN model, i.e., the generalized regression neural network (GRNN), to predict the ...
The solubility parameters of 1228 solvents, from all the chemical groups, were predicted using Genetic Algorithm-Based Multivariate Linear Regression (GA-MLR) and Generalized Function Approximation Neural Network (GRNN). GA-MLR was used to select the molecular descriptors, as inputs for GRNN. The ...
This study introduces a new and effective epileptic seizure detection system based on cepstral analysis utilizing generalized regression neural network for classifying electroencephalogram (EEG) recordings. The EEG recordings are obtained from an open database which has been widely studied with many differen...
