While I do spend lots of time pushing the idea of linear approximations on my students, we do need nonlinear functions to describe most interesting physical phenomena.

For this, you also need non-linear thresholding functions that adjust the weights between the layers of neurons.

This article reviews work on the planning of experiments with response functions nonlinear in some parameters. Apart from older work on dilution series experiments and quantal bioassays, this field is ...

Conventionally, the money demand function is estimated using a regression of the logarithm of money demand on either the interest rate or the logarithm of the interest rate. This equation is presumed ...

However, this cannot easily be achieved whilst retaining the conventional non-linear transfer functions, known as gamma curves, which were designed for CRT displays.

A screenwriter makes the morph from films to games--and starts thinking differently.
