[@deepakawasthi2540]

Excellent, to the point , very informative. great explanation

[@utkarshsingh2675]

Didn't know that roc curve is actually for varying threshold values...thanks for the video

[@anny23108]

Sir, that was an amazing explanation! Thank you so much!

[@anirbansarkar6306]

for the firs time I got the intuition for roc curve. Thank you so much Aman Sir

[@UnfoldDataScience]

You're most welcome

[@siccasim1520]

@@UnfoldDataSciencewas pretty good thanks

[@ajaykumar-rh2gz]

Hi UDF, I saw your videos very interesting. Thanks

[@SwethaNandyala-sf9lt]

I already knew the concept.. by I didn't think in this direction that it is at the model level and is one and only performance matrices which is unaffected by the threshold. Thanks for your Gyann :)

[@shreekrishna1518]

Thank you so much..i understand this concept more clearly

[@UnfoldDataScience]

You're most welcome

[@dr.muhammadjunaid949]

Well done. You have cleared my confusion

[@UnfoldDataScience]

Thanks a lot.

[@knubbe]

Best teacher!!

[@rahulsingh-qs7lm]

superb

[@RamanDeep-tj1jf]

Best video

[@explorewithskp1237]

Very useful sir 🤗 so Shared in grp

[@UnfoldDataScience]

Thanks a lot for sharing

[@Rider-jn6zh]

Please explain rnn and LSTM layers parameters...having lot of confusion in it..

[@shine_through_darkness]

Really great video bro!!! Can you please also put some videos for LLMs mainly peft

[@shreyasb.s3819]

Very well explained

[@UnfoldDataScience]

Thanks Shreyas. Pls share with friends as well.

[@hussainkanchwala968]

Great explanation!!

[@UnfoldDataScience]

Glad it was helpful!

[@squadgang1678]

Can you explain transformer and self attention model and explain difference between lstm and transformer

[@lenaara4569]

Thank you for the video. Do you know why the plot starts with threshold value =2 ? According to my understanding threshold should be between 0 and 1, because these are probabilities, correct?

[@murapakaganesh1108]

Sir please do a video on fbprophet

[@UnfoldDataScience]

Thanks Ganesh. Sure

[@shekharkumar1902]

Aman Sir , how can I join your coaching class? You are superb teacher.

[@UnfoldDataScience]

Thanks Shekhar. Please click on below link

[@jyotshanajha8316]

Sir please explain how threshold is different for each value. it should be same right? i am literally very confused with threshold value changing.

[@UnfoldDataScience]

Hmm...you have asked a very good question. It confuses many people
Let me try creating a video around it.

[@nooreldali7432]

How do we interpret the AUC value? for example the value you showed was 0.93, do we say it's good or bad? and how do we know?

[@UnfoldDataScience]

good, think like percentage of marks out of 100

[@sameenapajanikar624]

you must teach in detail, i dont know anything about tp,fn

[@eagleblaze9292]

It can't be applied for multiple classes classification is is true? Sir

[@ghadashafiq6698]

Have you found the answer ?

[@vedangchavan3321]

How to find optimal threshold?

[@UnfoldDataScience]

Business knowledge + Experience + What data is saying

[@ankitdhanore1355]

Sir first tell one thing how did you know that I'm learning roc auc and I'm getting confused in it .😂😂😂 Jokes apart , great knowledge ... Getting ready for interviews .😊

[@UnfoldDataScience]

Thanks Ankit 🙂.
