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.

Non-linear physics is the study of systems where the output is not directly proportional to the input. Unlike linear systems, which follow simple, predictable relationships, non-linear systems exhibit ...

The Southern Economic Journal features original, refereed scholarly articles in all areas of economics as well as contributions on the pedagogy of economics. The journal also contains occasional ...

You construct a generalized linear model by deciding on response and explanatory variables for your data and choosing an appropriate link function and response probability distribution. Some examples ...

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

Long wires or distant wireless communications always garble the transmission. How can an engineer cure that distortion? Turns out, a lot of math and a little experience can work wonders. This author ...

Asymmetric interactions between different species of molecules have previously been demonstrated to result in self-organized ...
