Many of you have asked me to share my presentation notes, and now… I have them for you! Download all the PDFs of my Notion pages at www.emmading.com/get-all-my-free-resources. Enjoy!

[@ShortSnoph]

This is a great overview of methods of feature selection. This is just what I needed! Thank you

[@olawaleawe9615]

I enjoy your videos. Good job!

[@16876]

Great as always :)

[@Doctor_monk]

Thank you for the video. Even though I know these concepts it helps to watch these again just as a refresher.
I know I am getting repetitive but would love it if you can share the notion books of these topics to make notes and quick review/reference. 😊😊

[@emma_ding]

Of course! I'm working on getting all notes organized and sharable in one location, will let you know as soon as they are ready! :)

[@Doctor_monk]

@@emma_ding thank you so much!!

[@jkaeromero2288]

Hi, amazing video; maybe can you do feature selection into networks?

[@maximilianozirion1587]

Muchas gracias te amo

[@sssam844]

Could you please attach subtitles to the video? I'm a bit deaf and using automated subtitles doesn't help a lot

[@emma_ding]

Will definitely consider adding the feature for future videos! Thanks for the suggestion.

I like your videos but could you please talk a little bit slower?

You can reduce the speed using playback speed in setting
