This video explains how to find a polynomial of at most degree d which is as close to going through a set of points as possible.

This video is part of a series of video lectures for the linear algebra class I am teaching.

Amazingly insightful - you finally opened my eyes! Thanks!

Thanks a lot but could you please explain why you multiplied with transpose matrix on both sides and how it leads to the best fiiting least square polynomial...

Loved your session! Could you please explain why do you say in the end that this equation from the used method- has the lowest sum of squares? What if a higher polynomial or some other ML method defines a better curve fit?
