WebThis paper presents a set of optimizations in learning algorithms commonly used for training radial basis function (RBF) neural networks. These optimizations are applied to a RBF neural network used in identifying helicopter types, processing their rotor sounds. The first method uses an optimum learning rate in each iteration of training process.
