Thank You so much Sir. Your video series on machine learning using R is the best and the most helpful among all the R ML content that I have seen on the RU-vid platform. Sir, I have a small doubt regarding Random Forest. Can we also use it for scenarios when the dependent(target ) var is continuous? And also is there any way to tackle missing values in R when we are working with Random Forest?
@bkrai
@bkrai 2 года назад
That will be regression trees. See link below: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-hCLKMiZBTrU.html For handling missing values, refer to: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-An7nPLJ0fsg.html

Thanks for the video, it is really helpful. I step on var importance plot, it is useful to get the most significant variables. Also it would be really interesting to show the same output but for each class instead to see the variables which best describe each class. By any chance, do you know how to get that idea? I sought though different websites but couldn't get a clue.

Probably you can calculate averages for each level of a important variable. That way you can see their impact.

Dear sir, Please advise on below request - I think ROSE package work for binary classification and doesn't work for multi-class classification. How to do for this multi class classification ? Can you please upload a video for detailed data manipulation from raw data to ready data to process . Again thanks for great support. Regards, Hanspal Yadav

As usual brilliant work. Learning alot from these videos. A small question though. ind=sample(2,nrow(mydata),replace=TRUE, prob=c(0.7,0.3). Can I use this code for my dataset when i have alot of classes? or if theres a video talking about what this sampling does? Thank you.

You can use this approach for many classes too. For explanation of data partitioning see: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-aS1O8EiGLdg.html
