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 ...

Function definition and graph of linear/nonlinear functions such as quadratic, cubic, absolute value, piecewise-defined, rational, and power function. Additional topics with functions included such as ...

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 ...
