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

    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!

    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.

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

    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.

    '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.

    What metric to use for multiclass classification?

    • @ritvikmath
      @ritvikmath  3 года назад +5

      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.

    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:)

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

  • @pedrogerum
    @pedrogerum 3 года назад

    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?
