PPT-Introduction to Neural Networks

Dr David Wong with thanks to Dr Gari Clifford GIT Overview What are Artificial Neural Networks ANNs How do you construct them Choosing architecture Pruning How do you train them. Bullinaria 2004 1 Introduction to Radial Basis Functions 2 Exact Interpolation 3 Common Radial Basis Functions 4 Radial Basis Function RBF Networks 5 Problems with Exact Interpolation Networks 6 Improving RBF Networks 7 The Improved RBF Network brPa Easy to understand Easy to code by hand Often used to represent inputs to a net Easy to learn This is what mixture models do Each cluster corresponds to one neuron Easy to associate with other representations or responses But localist models are ver 1. Recurrent Networks. Some problems require previous history/context in order to be able to give proper output (speech recognition, stock forecasting, target tracking, etc.. One way to do that is to just provide all the necessary context in one "snap-shot" and use standard learning. Brains and games. Introduction. Spiking Neural Networks are a variation of traditional NNs that attempt to increase the realism of the simulations done. They more closely resemble the way brains actually operate. Deep Learning @ .
