The performance of recently developed neural
network structure, general regression neural network
(GRNN), is examined on the medical data. Pima Indian
Dabetes (PID) data set is chosen to study on that had
been examined by more complex neural network
structures in the past. The results of early studies and of
the GRNN structure presented in this paper is
compared. Close classification accuracy to the
reference work using ARTMAP-IC structured model,
which is the best result obtained since now, is achieved
by using GRNN, which has a simpler structure. The
performance of the standard multilayer perceptron
(MLP) and radial basis function (RBF) feed forward
neural networks are also examined for the comparison
as they are the most general and commonly used neural
network structures. The performance of the MLP was
tested for different types of backpropagation training
algorithms.
