Singular Value Decomposition (SVD): Overview

[@aravindhvasu195]

Oh my god, was going through the control bootcamp, hit a wall with SVD, the next day, series in SVD. Thanks a lot for these gorgeous lectures.

[@philippbeer]

This is a fantastic channel Dr. Brunton! I just stumbled across it searching for SVD and got hooked on the content. Your unpretentious, clear and thorough explanations are a delight. They way you've set up the board and screen projection is fantastic. I'm really impressed with this and want to say thank you to you and the team that made this production possible.

It's really interesting to see how left-handedess works when mirrored. Quite an effect on the brain!

[@danluba]

Dude, I've been trying to figure out whether he's writing everything backwards, which side his parting is on, whether he's left-handed or right-handed, married or not... Do you understand what magic is this?!

[@shailshah5803]

are you writing backwards on a glass board or is this some kind of editing magic ... this keeps me up at night

I always wondered how these videos are recorded. Is there a glass between you and the camera? Great content anyways!

[@Sonnentau1]

Blind guess: Its glass and than they flip the video horizontally... Or Mr Brunton is not only a genius but is also able to write mirror font. I finde both equally likely

[@jobleser]

@@Sonnentau1 Dr Brunton seems to be actually left-handed as per other videos; so the glass/flip-video hypothesis/trick seems likely. Neat.

[@radarmaker1]

Wedding band on the "right" hand, so think he's left-handed and image flipped :)

[@hariprasadhparthasarathy6360]

I have asked Prof brunton in another video about the exact same thing and he replied with 'years of practice' :)

[@dylangomes3853]

If there is glass, the writing is still backwards relative to the writer. I don't see how it matters if you flip it.

Hi! Thank you so much for these vids. Realized yesterday that I couldn't make myself use SVD unless I understand the logic of it. Could someone possibly recommend the topics I should look into beforehand in order to understand it and subsequent topics? I don't have a foundation in Maths beyond High School Level.

[@ronronn3148]

you should learn some linear algebra. you need a little calculus to do linear algebra sometimes, but it can mostly be done with integration and differentation. easy topics to look into, you're going to be using basic integration and differentiation. linear systems, manipulating them, understand matrices and how to manipulate them, how to find eigen values and eigenvectors, what eigenvalues and eigenvectors are. kinda gives you a base level for linear algebra.
