I recently came across 3Blue1Brown's "Essence of linear algebra" YouTube playlist. As the title implies, it covers the basics of linear algebra. Instead of focusing on the math though, it lays down a foundation that gives you a visual intuition that helps you reason about it. I would highly recommend this if you've never really grasped linear algebra that you've been taught in university, or if you've never gotten around learning about linear algebra at all. While watching the first video, I decided to code it all out in Scala to let it materialize.

Linear algebra is a field of mathematics and an important pillar of the field of machine learning. It can be a challenging topic for beginners, or for practitioners who have not looked at the topic in decades. In this post, you will discover how to get help with linear algebra for machine learning. Top Resources for Learning Linear Algebra for Machine Learning Photos by mickey, some rights reserved.
