Finally, someone who introduces the problem first, the need, and then shows the solution. Most videos give you the solution and don't give you the problem at all, so you're left wondering why the thing exists in the first place. Great video!

I don't know if you realize how good you are!

Finally, a clear video on PCA for a guy coming from biomedicine.
Thank you!

This "high level" explanation was just what I needed to get rid out of doubts about how to implement PCA. Thanks so much for your effort. You got 1 new follower.

Finishing a degree during COVID-19 and this man has explained better in 6 minutes what a lecturer I'm paying £9, 000 spent 3 different 1 hour teams meetings trying and failing to explain

[robertc]

You have a rear gift of explaining things in a very clear way my friend. I’m curious to see the next video!

[Information-Overlord]

All the great reviews below are understatements ;-)

[noahrubin]

This was outstanding. Exactly what I needed.

I started teaching business analytics and find your teaching method as very consumable. Assuming length and weight of kitties is correlated I assume you could have just one PC.

[frenchmike]

thanks for explaining it in plain english before going into some crazy math. I appreciate this

[sammyj]

One of the best channels which go in depth while still keeping it clear. Thank you for creating such content!

Hey Ritvik,

I might be your biggest fan! Whether I'm cramming for an exam, trying to understand a paper, or just killing time on a curious Saturday, I always look for your videos first!

That said, it would be very helpful if you could include a link to part 2 in your description or at the end of the video.

Thank you for all you do :)

[zakzeaxer]

looked a bunch of videos, but only this explained me well the interest of PCA !

[xjggjmq]

fantastic video, the examples and using real numbers really clarifies things tysm !!

[sethquigley]

Awesome work man! Thank you and God bless

[priyankagupta]

When we study, our aim is to get clarity where we will use this concept, you explained it very well. Thank you so much.

[francescodipietro]

Thanks man, i really need this kind of video to understand the topic

You just saved me a lot of time and stress with this simple straightforward film. Thanks a lot.

Please make another one like this on the fisher-face and LDA algorithm. 😇😇😇

Absolutely genius. I was looking for an intuitive understanding and here you se brother.
Can you request you to do a few videos on locality preserving projection?
