The ROC Curve : Data Science Concepts

[@sindytindy]

The connection to the business scenario really helps to understand the purpose and movements of the ROC... Thank you for your excellent explanation.

[@ritvikmath]

Glad it was helpful!

[@SouravGhosh-yb3oc]

Hands down the best intuitive explanation of the concept of ROC. Not even the gold standard books has taken the pain to explain this way. You inspire us!

[@kavinarasu6610]

I'd be a sinner if I would just walk away after watching such an amazing video! I'd want this video to be shown first on YT when someone searches for 'ROC curve'. Thanks a lot for this, mate!

[@Anooshehk]

Thank you so much! You are a MASTER Teacher. It is very hard to find teachers who teach in a way that makes sense and you have that gift. I LOVE your channel and wish you tons of success. I am an MIT student and will share it with my friends.

[@ritvikmath]

Wow, thank you!

[@vamshi755]

Watched lot of other videos, I got ROC concept 100% without any doubts from this video. Easy to understand. appreciate you effort.

[@ritvikmath]

Great to hear!

[@PeterRiccelli]

This is hands down THE BEST explanation of RoC construction, dynamic and interpretation I have ever viewed.

[@c0t556]

You are literally the best teacher for data science on KZbin!

[@ritvikmath]

Glad you think so!

[@QuantumQuasar91]

This is gold, you deserve way more subscribers! Thank you for using a business case, it makes it easier to understand.

[@hassanshahzad3922]

i can watch that the whole night! this is awesome!

[@vinceb8041]

Your format of hand-drawn presentation is amazing, it helps tremendously with understanding complex topics! Keep up the great work, it is much appreciated. :)

[@ritvikmath]

Thank you very much!

[@TheTriggerday1]

Love it! The only thing I'd add is clarify the underlying basic assumption that the predictions of the model are spread across this 0-1 probability space with a lot of mass on either ends and decreasing mass as you go to the center but more mixing.

[@kaduflutist]

Excellent teaching! I love to understand how things work and you does a good job on it.

[@shubhampandilwar8448]

Very well explained. The drawings are really helping to uncover the intuition behind them.

[@amaurylaine2093]

Best Explanation of the ROC curve I have seen on KZbin so far!

[@3omarmaryam]

one of the best channels ever. very informative straight to the point and takes my understanding to a whole new level. I cant thank you enough

[@alexanderbalasky6174]

Your explanations are absolutely the best.

[@EgorMatsuk]

One of the best channels with very intuitive and structured explanations. I wish I knew about you during my university study 👨‍🎓 Thank you!

[@SonyaO123]

'This is the best ROC explainer video that I have found to date...And, I have watched a lot! Thanks so much. Very clear presentation of key concepts illustrated with a realistic example. The pre-prepared hand drawn whiteboard illustrations were brilliant and easy to understand as your went through the video. I think I might use that technique in my own teaching vs drawing as I go. So much more efficient.

[@xavecoding]

An amazing video, as usual. A clear overview of the content is provided at 13:40 =D

[@amnont8724]

Your channel is outright amazing!! Discovered your channel recently, you explain things in such a short, simple and intuitive manner

[@ritvikmath]

Awesome, thank you!

[@atefe3919]

you are truly a gifted teacher, thank you so much for helping me getting ready for my interviews!

[@kaduflutist]

I agree!

[@eberlicouto1210]

Your channel is the best, thank you. I got stuck in my learning, but then found answers here (a few times already). Think I will just come here directly next times. 😄

[@ritvikmath]

Happy to help!

[@teegnas]

this is just ... simply amazing!

[@ritvikmath]

thanks!

[@synthds3897]

Very articulate presentation. Good job!

[@ritvikmath]

Thank you kindly!

[@rhyogi]

Good video, I also think of ROC Curve as a visual summary tool to help select the most suitable threshold, without having to go through lots of different confusion matrices.

[@ritvikmath]

Great point!

[@etnies397]

So helpful! I'm in grad school studying eyewitness testimony and your video helped so much!

[@diegososa5280]

Thank you so much, the best teacher out there

[@ritvikmath]

Wow, thank you!

[@pekpro1611]

Very useful video, you always make everything so so clear and understandable. Thanks!

[@ritvikmath]

Happy to hear that!

[@naveenreddy6599]

best explanation i have seen so far, Ty

[@stephonhenry-rerrie3997]

this was a very well explained video. thanks so much. this concept is not usually taught that well to be honest so you cleared up a lot of confusion that I Had.

[@keshavsharma267]

What metric to use for multiclass classification?

[@ritvikmath]

Good question. We can still use this ROC curve idea and extend to multiclass. Say we have three classes {0,1,2} and suppose class 1 and class 2 we care about most. Then, we can build one ROC curve for class 0 vs class 1 and one for class 0 vs class 2 and try to optimize both of these.

[@keshavsharma267]

@@ritvikmathGot it. Thank you so much

[@apterixbr]

as always, you are very clear and explain everything. i always recommend your videos. thank you!

[@pepsibrandambassador]

EXCELLENT VIDEO!! CLEARED MY CONCEPTS BEST.

My mind is churning with new information!

[@ritvikmath]

love the pun

[@rohitnema6933]

Excellent Sir .Hats off to you 💗❤️❤️

Millions of thanks!

[@vps071]

Fantastic explanation!

[@ForcesOfOdin]

Instantly subscribed! Great video, thank you so much.

[@ArunKumar-yb2jn]

You explanations are so cool!!

[@maciejk2306]

Another video about threshold selection (based on ROC AUC and TPR/FPR or maybe some different methods?) would be a great complement to this!

[@ritvikmath]

Great suggestion!

[@honeyBadger582]

Great as always! Waiting for that SVM video

[@ritvikmath]

Coming soon!

[@vinceb8041]

yesss, awesome! :D

Glad it was helpful!

[@sylvan4309]

this helped me SO MUCH. Thank you!

[@sans_12]

Hi Ritvik. Thank you for the great content and really loved your explanation on ROC curve-v helpful. Quick question-so why do we use Precision Recall instead of ROC curve. Do you have video on the same?. I read Precision Recall curve is used more in imbalanced dataset scenario-any inputs here? Thank you:)

[@khaldoun6260]

awesome job ...thanks for the great content

[@ritvikmath]

Thanks for watching!

[@absoluteanagha]

Very good explanation!

[@absoluteanagha]

Let me just order a pizza and watch all of your other videos as well.

[@vivek6389]

Hi Ritvik, a quick question why dont we set our probability threshold as 0.5 in case of binary classification lets say.

[@jshu7514]

definitely the best !!!

[@dhendroid2373]

Give this man a subscribe!!!

[@nicop175]

Great content. Thank you!

[@ritvikmath]

Glad you liked it!

[@ZettyIlham]

THANK YOU SO MUCH. IT'S VERY WELL EXPLAINED.

[@pedrogerum]

Why do we use the area under the curve vs using the minimum distance from the star point (top left corner) to the ROC? Is there any official reason for that?

[@pypypy4228]

Does it assume that a user of our modern will adjust this threshold according to his business scenarios at different time?

[@ritvikmath]

Yep that’s right

[@cleansquirrel2084]

Love your videos!!

[@ritvikmath]

Thank you!!
