  This motivates using Radial Basis Function neural network structure in SVM. RBF neural network provides a smooth interpolating function, in which the number of basis functions are decided by the complexity of mapping to be represented rather than the size of data. RBF can be considered as an extension of finite mixture models.

  The neural network was trained with MetaNeural™, a general-purpose neural network program that uses the backpropagation algorithm and runs on most computer platforms. The neural network was trained on the same 10 patterns that were used for the regression analysis and the screen response is illustrated in figure 2.5.

  A neural network with a similar capability is called a self-organising system because during training, the network changes its weights to learn appropriate associations, without any right answers being provided. The propagation of biological neural activation via axons can be modelled using a Mexican hat function:

  Neural networks process information in a similar way the human brain does. The network is composed of a large number of highly interconnected processing elements (neurones) working in parallel to solve a specific problem. Neural networks learn by example. They cannot be programmed to perform a specific task.

  Example: The objective of this effort is to develop a precise form of a neural-network and to determine, in a hybrid scheme with some conventional pattern recognition algorithms, the usefulness of the neural-network. The tools for efficient computer utilization to accomplish this task must also be developed and specified.

  The neural network model building platform is shown on the following page. There are numerous options that can be set which control different aspects of the model fitting process such as the number of hidden layers (1 or 2), type of “squash” function, cross-validation proportion, robustness (outlier protection), regularization (similar to ridge and Lasso), predictor transformations, and ...
