- The ROC curve is a very effective way to make decisions on your machine learning model based on how important is it to not allow false positives or false negatives. In this video we introduce the ROC curve with a simple example.

I have a great story about "a model that predicts worse than random". Many years ago when I first became involved in developing ML tools at work, one of my seniors noticed that the tool my team was working on was predicting things worse than random, which we found very surprising, because we had tested it before and it worked well. In fact, he scolded us for making such a terrible model, saying, "You would be better off if you guess the opposite of what your model was guessing!" Sure enough, we discovered that some refactoring had led to an extra negative sign being introduced that had flipped the direction of our model. Removing the negative got us back to a very accurate prediction!
probably the best explanation- simple and effective illustrations, thank you very much!
Just want to leave a comment so that more people could learn from your amazing videos! Many thanks for the wonderful and fun creation!!!
Absolutely brilliant! You're the one guy I dont mind spending a lot of money on your courses for
The final prediction rotation on RoC curve is really inspiring
Amazed with your teaching style! Kudos Dr. Serrano
Very clear explanation!
Your explanations are the best!!🔥🔥🔥
Great lecture. Thanks.
Wish you were my teacher when I was in school/college :/ Nevertheless, I'm grateful that I am getting to learn from u via youtube... Big thank you... Stay blessed
Great and Amazing explanation like usual Serrano
by far the best video on ROC curve.
Thanks, you helped me clear my mind up.
Awesome! This video is simply a gift; thanks for sharing this.
Very clear. I come to realize the different curve is due to different threshold.And some threshold doesn't hurt FPR in some cases as you mentioned.
Insightful, thanks a lot!
Nicely explained. Would have been great if I had your video 30 years ago😅
fantastic, thank you very much!
thanks for the appropriate illustrations!
best intution given on this topic ever !!
Amazing video ❤
Great explanation. Brilliant.
Best on the globe 💯💯💯🙏🏻🙏🏻🙏🏻
Great video! Thank you so much
Thank you so much
Great video thanks
This is brilliant
You're amazing!
wow, thank you
Perfect!
Thank you :)
Thanks Luis. This is the simplest and best ever tutorial in ML I have come across. do you have more courses? udemy? or other platform?
Gracias Jorge! Yes, this one! www.udacity.com/course/deep-learning-pytorch--ud188
And more to come soon, I'll announce them in the channel!
(also I'm sorry for the very late reply) :)
@@SerranoAcademy I didn't know your deep learning course was free! 😮 Every course I found in Udacity through search was around $1,000. While I can't afford that price point, I still want to support your work. Besides buying your book and subscribing, are there any other ways?
Very informative video, just one question can this be used as metric for multilabel classification (considering using machine learning algorithms not neural-nets)? I mean what can we get from roc-auc curve about multilabels and if not what will good metric to look for?
I am confused about what is referred to as "model". When we say that "the greater AUC the better the model" it seems to me like it's a bit of a misnomer since AUC characterises the whole set of the models (which we can obtain by translating the line from one extreme to another) but not a distinct one. A point on the curve, from the other hand, seems like a legitimate representation of "a model". It seems like these two terms are used interchangebly in the video and this is a root of my confusion. Other then that, it's a great visual!
Did you mean "so that it won't have any false negatives at all" @2:19? By the way , great video and explanation style!
awesome
I am disappointed in all the professors at my university who proudly overcomplicate things. After watching your videos, all the math and advanced topics make sense and become very obvious. This channel and your videos deserve to be called "must-watch," just like Jeremy Howard's and Andrew Ng's courses. I wish your full courses were available on a platform more affordable than Udacity😅
How can you make it so simple to learn?! when I need to revisit some concept I always search for: "Something that I need to learn Luis Serrano" :)
Thank you Rodrigo, that's such a nice thing to hear! :)
I come to say exactly the same thing! We need a video from Luis to tell us how he understands everything in simple terms like that!
Mmmm the temptation to draw a curvy overfit line through the data
Hey, I wonder how could we decide in a similar situation when the number of features is not just x & y but say for example 3 features or even more?
Hi, the manning website does not work. I am unable to buy the book :(
Hi Ashay, sorry about that. Did you try this one?

Let me know if that still doesn’t work. Thank you!
¿hay este vídeo en español?
Hola Jairo! Este todavia no, pero pronto lo pongo. Por ahora en este canal hay algunos en espanol, pero mi plan es ponerlos en un canal separado. Por aca hare los anuncios!
You are god
Luis...its my request to make series of videos of quantum computing bay sian learning and reinforcement learning..I am ready to pay for it..it is much needed to society ...the godly person like you can make the life of people better
Trust me you are here for giving like god ...please think of my request ..
