Web2. RBF and MLP belong to a class of neural networks called feed-forward networks. Hidden layer of RBF is different from MLP. It performs some computations. Each hidden unit act as a point in input space and activation/output for any instance depends on the distance between that point (Hidden Unit) and instance (Also a point in space). WebApr 12, 2024 · The analytic hierarchy process is used to construct the health evaluation index system and grading standard of small- and medium-sized rivers in the region. Based on the principles of RBF and GRNN neural network algorithms, the river health evaluation models of radial basis function neural network (RBF) and general regression neural …
Webgatech.edu 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.
