This guy is definitely one of the best teacher available on TH-cam Simple but effective explaination Lots of love for you Sir ♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
The explanation is great! Why is it used? 1. ROC & AUC - Plotted between TPR & FPR, helps in - visualization & explanation & selection of a required threshold for the model! What is ROC & AUC? 2. ROC - (Receiver Operating Characteristic curve) that you have drawn & AUC is the - (Area under the curve). How does the curve look like? 3. AUC should be greater than the 0.5 line drawn, which indicates a better model. 🙇♂️🙇♂️🙇♂️
great explanation video..anyone confused or overwhelmed about how much to study and from which channel to study...simply follow krish naik playlist from start to end.....
Hi I couldn't find anywhere part 3 - performance metrics for classification problem part 3 ( you said in the first one there are 3 parts I only found 2).By the eay, I became a memeber more than half a year ago to support your work, because you are an excelent lecturer and you helped me a lot.
Krish, please make a video on "implementing all the Metrics For Classification Problem in ML by taking improper data set" as you mentioned in one of the videos of ML playlist (#1:05 minute of Tutorial 34 of Complete ML playlist)
for the threshold value of y^=0.4 and y^=0.6 , tpr and fpr values is same i.e.,(0.5,0.5) and for y^=0.8 is (0,0.5). Now the graph will be different and AUC might be less than 0.5.
Hi...can you share the link for part 3 of the performance metric video. Also, can you share any real life example when domain expertise would want threshold to be say 0, 0.6.?
Krish, at the end of this video, you said: "if they focus on both TPR and FPR, we can also choose TH(0.4) at that plot". But in real ROC there are always a lot of inflection points like TH(0.4), then which inflection point should we choose?
hello sir, i am working on my final year project, Resume classification and ranking system using knn and cosine similarity, the roc auc curve for all my class label came 0.5, what should i do?
Great explanation but I didn't get how to take the threshold values , this is , the values we have taken to predict and draw ROC. Can we select them randomly or is there a way?
Hi Krish, Suppose i want to set the threshold at .75. then how i can do this in python code. is there any parameter in ruc_curve method or have to do it by using logic/code.
Sir please make videos on web scrapping for beginners.. please sir and I am anabel to get the link of AQI website which you have shown in the video ....but please make more videos on web scrapping..
Hello sir , just a doubt need your help , I have a sample value, a control value and also a AUC value … I just want to plot 2*2 confusion matrix table… can you please help me
Hi Krish, your videos are very informative and helpful. I saw your video where you explained ROC-AUC based on thresholds in Logistic Regression. What is the intuition about thresholds for other classification models? For example, a decision tree will split based on feature value to determine the class, how is ROC constructed here? Similarly, for other classification algorithms, how is ROC constructed?
thanks for your knowledge Krish sir, I am new to date science ROC used to evaluate the logistic regression only or do we have any uses can anyone help with this
Can someone tell that as the sir said we have to see all these different metrics when we have an unbalanced dataset if we have balanced datasets then only accuracy is enough?
This channel is a gold mine. Thank you for your knowledge Krish.
Indeed
Agree
This guy is definitely one of the best teacher available on TH-cam
Simple but effective explaination

I swear to God man, I learn more from you than my professors at school... you're saving my assignments
In which school we are teaching ML?
Bro, You are a gem. I mean not a single unnecessary word, everything is explained clearly and concisely. Many many thanks brother
really ur communication ur voice and the way u explain it stole my heart broooookeep rocking broooo
Sometimes, I check this, that and then just search if you have made a video on the topic. No one can just simply explain better. You are an AVENGER.
Thanks krish.My doubts about ROC ad AUC are now clear.
you're a true supervisor for supervised learning! 🌷
great explanation video..anyone confused or overwhelmed about how much to study and from which channel to study...simply follow krish naik playlist from start to end.....
Please consider using manual focus and iso :D
Hey Krish, you are amazing! You explain topics clearly. So, everybody can understand it!
Hats off Krish..u r so deep in knowledge
Hi I couldn't find anywhere part 3 - performance metrics for classification problem part 3 ( you said in the first one there are 3 parts I only found 2).By the eay, I became a memeber more than half a year ago to support your work, because you are an excelent lecturer and you helped me a lot.
Best explanation on the internet. Thanks Krish!
Very clear and crisp explanation, great job👏
After reading about roc and auc, your example calculating manually the values was perfect to finally understand this topic. Thank you!
I just hit the jackpot with this channel, thanks alot
Me too
Finally I have understand ROC....Thank YOu Sir
Krish, please make a video on "implementing all the Metrics For Classification Problem in ML by taking improper data set" as you mentioned in one of the videos of ML playlist (#1:05 minute of Tutorial 34 of Complete ML playlist)
8:20 here I finally understand how to read the ROC curve. You really are great
Sir people like you should be admired ...big fan hope we meet one day
Krish you explain data science concepts so clearly that I have become fan of your's !!! thanks a ton man!!!
awsum explaination...ALL THE BEST for all your upcoming videos #Krish.
totally clear .. you way of explanations are really very amazing.
Brilliant. You are officially Sensei.
Superb explanation👌👏👏👏....Waiting for part-3. Please upload it as possible as sir
Very nicely explained. Thanks for sharing.
The best explanation ever seen, thank you
Awesome video sir.
I love it😍😍🥰🥰😘😊😊🙏🙏🙏🙏🙏👌👌👌👌
for the threshold value of y^=0.4 and y^=0.6 , tpr and fpr values is same i.e.,(0.5,0.5) and for y^=0.8 is (0,0.5). Now the graph will be different and AUC might be less than 0.5.
Yes!
How to reset the threshold value?
0:52 how to determine the threshold. can we set the threshold ourselves?
really awesome explanation....
superb explanation loved each bit😍😍
You explained it so nicely and make me understand the roc and auc concept so easily. Thanks a lot krish
Nice Video and clear explanation. Thanks a ton ! .. Please do post part-3 of the metrics soon....
What an informative video. Really amazing!
Lovely Explanation.
Brilliant explanation. Please make part 3 of this video.
Krish I really appreciate your effort in sharing your knowledge. Thanks
Thank you for this video. Eagerly waiting for part 3.
Very nicely presented ...clearly understood . Thank you sir
Your explanation is just amazing go ahead man
Hi Krish you are really superb... Excellent knowledge, well explained
Thanks Krish. This saved me a couple of hours
Hey Krish , Did you uploaded Part-3 of this video (i.e. Performance Metrics for Classification problem) ?
Hi...can you share the link for part 3 of the performance metric video.
Also, can you share any real life example when domain expertise would want threshold to be say 0, 0.6.?
Maza agaya bhai dekeke. Subscribed. The thing what I felt lacking was. More explainanation
Thanks a lot sir. I was seriously waiting since your last video on performance metrics.
Fantastic!
Great video, thank you Krish
Awesome Work Sir !!
In the case of binary classifier that outputs 0 and 1 labels how can we calculate auc score and roc curve
Awesome lecture
very short and srisp, i love it
Krish, at the end of this video, you said: "if they focus on both TPR and FPR, we can also choose TH(0.4) at that plot". But in real ROC there are always a lot of inflection points like TH(0.4), then which inflection point should we choose?
So comparing the Andrew Ng video, the true positive rate is same as recall? and the false positive rate is same as precision?
very nice explanation
hello sir, i am working on my final year project, Resume classification and ranking system using knn and cosine similarity, the roc auc curve for all my class label came 0.5, what should i do?
Hi Krish, Can you please upload Part-3 so that everything can be understood
Great explanation but I didn't get how to take the threshold values , this is , the values we have taken to predict and draw ROC. Can we select them randomly or is there a way?
Understood ROC. can any one suggest me video on "(CMC)Cumulative Match Score Curve"
Hi Krish, how did you come up with original y hat?
Hi Krish, Awesome explanation. Thanks a ton. Could you please help us by giving an example (Part-3) for all the performance metric in python.
Hi Krish, awesome teaching skills... please upload all parameters in python programming language take an example like iris data
Thanks Krish
Hi Krish, Suppose i want to set the threshold at .75. then how i can do this in python code. is there any parameter in ruc_curve method or have to do it by using logic/code.
Can we use AUC-ROC for multiclafication problem?
Keep up the good work.....Great explanation!
Sir please make videos on web scrapping for beginners.. please sir and I am anabel to get the link of AQI website which you have shown in the video ....but please make more videos on web scrapping..
Hello sir , just a doubt need your help , I have a sample value, a control value and also a AUC value … I just want to plot 2*2 confusion matrix table… can you please help me
Super Sir. Very clear
Amazing explanation
One construtive feedback: please lock your phone's focus so that it doesn't go haywire like at 1:47
perfectly explained
Good video Krish, could you please create a video on Cohen-Kappa score.
You are awesome krish. It takes so much effort to reach here. Brilliant :D
Thank you sir....It was very helpful.
nicely explained
Awesome video.
Great video Sir.
it really helped thnx

I am new to date science ROC used to evaluate the logistic regression only or do we have any uses can anyone help with this
awesome !!
Excellent
CAN YOU PLS EXPLAIN MULTICOLINEARITY AND HOW TO AVOID IT ? PLS or PERTUBATION TEST
You have great knowleg...Thanks a lot
Explain about epoch and its graphs with accuracy, Precision, Recall, f1Score. Also show in python or matlib how to draw
Sir can you plz make videos on statsmodal and scipy library
Can someone tell that as the sir said we have to see all these different metrics when we have an unbalanced dataset if we have balanced datasets then only accuracy is enough?
You can use precision & recall metrics,
Krish sir...... Hrithik Roshan ke bajaae aapko le rahe hain agli Krish Movie mein ??? Hero ho aap sir
sir can you explain roc auc in context to drought stress detection
hi krish in the previous lecture u said fpr =fp/p =fp/tp+fn now in this video it is fp/fp+tn which one is correct
what is the meaning of threshold value
krish please make part 3 and also list some performance matrix for multiclass classification.
How to use ROC AUC for multi-class problem?
Thanks! really.
