Python function keeps returning nan?

Gradient Descent converging faster for one parameter than the other parameter

QUESTION

Python function keeps returning nan?

Asked 2019-May-12 at 00:36

I am currently learning python by rewriting some of the old programs I wrote using other languages. But for some reason, I keep running into an issue where a function call keeps returning a nan. Below is a code snippet.

The function theta0PartialDerivative returns a number if I call it outside the gradient descent function, but returns a nan otherwise. I am unsure what the issue is?

Found the problem. Alpha, the step variable, was too large (for the dataset I was dealing with) and caused the partial derivatives to diverge instead of converge. I changed alpha from 0.5 to 0.13 and it works

First of all you have to look at speed of convergence to global minimum not at speed of changes of bias. There are no error in model (Maybe you just forget 2/N coefficient but for m and b coefficient this parameter will be 1.).

As you know gradient descent method is using error from prediction for updating weights on each iteration. So if your bias get small error then updates will grab small changes. It's normal behavior for model.

There are example with good explanation.

PS. Custom change for learning rate can lead you to anomaly behavior and problem with reducing to gminimum. Recommend this course.
