Much scientific research across a range of disciplines tries to find linear approximations of nonlinear behaviors. But what does that mean? Spend some time browsing around the web site of MIT’s ...

Investopedia / Michela Buttignol Nonlinear regression is a form of regression analysis in which data is fit to a model and then expressed as a mathematical function. Simple linear regression ...

In one variable, a linear function can be written as follows ... If one variable increases then the other variable decreases. A nonlinear relationship can be seen by scatter plots on a graph ...

It is often said that grief isn’t linear; it doesn’t plod in a predictable straight line, but takes terrible twists and turns, rearing up without warning.

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. The tradeoff for that is ...

For this, you also need non-linear thresholding functions that adjust the weights between the layers of neurons. “What makes deep neural networks so powerful is that we’re able to map very ...
