Let us visit an interactive visual cognitive tool for the basics ideas in linear regression:

The following video is a very concise and thorough treatment of linear regression for those who have taken the 200-level linear algebra. Others can fully understand it with some effort and revisiting.

(watch now 11:13):

Ridge regression has a Bayesian interpretation where the weights have a zero-mean Gaussian prior. See 7.5 in Murphy’s Machine Learning: A Probabilistic Perspective for details.

Please take notes in mark-down if you want.

For latex math within markdown you can do the following for in-line maths: $$\mathbf{A}_{i,j} \in \mathbb{R}^1$$. And to write maths in display mode do the following:

$\mathbf{A} \in \mathbb{R}^{m \times d}$

You will need to write such notes for your final project presentation!

Covers the training, test and validation and grid search… ridger regression…

Take your own notes if you like.
