Notes on ridge functions and neural networks
WebRecent years have witnessed a growth of interest in the special functions called ridge functions. These functions appear in various fields and under various guises. They appear in partial differential equations (where they are called plane waves), in computerized tomography, and in statistics. WebWhere do we use Ridge Functions? Neural Networks{ One of the popular neuron models is that of a multilayer feedforward neural net with input, hidden and output layers. In its simplest case, and without the terminology used, one is interested in functions of the form Xr i=1 i˙ n j=1 w ijx j + i!; where ˙: R !R is some given xed univariate ...

Webenough to solve the problem at hand. Shin and Ghosh (1994) proposed ridge-polynomial networks (RPNs) with universal approximation capabilities, trained using an adaptive net-work construction algorithm, and consisting of components that generalize PSNs. A ridge polynomial network computes a function of the form WebBetter Neural Network Training; Convolutional Neural Networks 109 – “Centering” the hidden units helps too. Replace sigmoids with tanh = e e e +e = 2s(2)1. [This function ranges from 1 to 1 instead of from 0 to 1.] [If you use tanh units, don’t forget that you also need to change backprop to replace s0 with the derivative of tanh ...
