Best video on Random Forest
Thanks for comments!
Great video, thanks for sharing your understanding on RF....
Thanks for comments!
Thanks, i am happy if you share videos for prediction as the above is about classification.
You should be my lecturer Sir because within 30 min, you were able to simplify something that i couldn't understand in class which took me weeks of research
Thanks for comments!
Hi Bharat, i don't normally comments on youtube videos, but your explanation on each and every details is excellent. I hope you come up with more videos in R. Thanks a lot.
Thanks for your comments! For more R videos you can try following links:

I like your explanation.
thank you sir.. excellent video
Undoubtedly Awesome Stuff
Thanks for comments!
Sir, really, u r the man. thank you.
Welcome!
You have the best damn video's. You are so thorough and I love that you don't use easy data sets.
Thanks for comments and feedback!
@@bkrai Absolutely! This may be asking a lot, but it would be really nice to see your spin on the Titanic Kaggle data set.
I'm adding it to my list of future items. Thanks
@@bkrai Awesome! I super excited. I have almost done every classification ML algorithm for the data set. But, I know there is massive room for improvement. Feature engineering was a very interesting process. I am a data analyst by trade, but I have never gone to this extent of creating features. Most of our features are already well defined within our business model.
Thanks!
Great video. Your video in CART was also excellent
Thanks!
are you available for consulting?
You have explain this very nicely. Very good video.
Thanks for comments!
Man, you are probably the best dude when it comes to R. You should consider teaching R courses on Udemy. Or come teach in NYC!
Thanks for your comments!
Thanks for the knowledge
Thanks for comments!
Hello Dr. Bharatendra... Thanks for you video
You are welcome!
This was awesome. Thank you!!!
thanks for comments!
Best tutorial Video for Random Forest in R so far! Thank you Mr. Rai. And I have one more question---I'm trying to predict the Player of the Week (NBA) based on the historical data. Given that the NBA select POW weekly based on the player's stats of that week compared to others, how should I deal with the data.For example, I have all 88 weeks dataset for all players, how should decide the which part the TRAIN/TEST data is? I can't just combine them together, can I?
Very good Video...keep it up thanks for sharing with us.
Thanks for comments!
Thank you so much sir! it was super helpful
You are welcome!
Thank you very much for this amazing so helpful video (y)
Thanks for feedback!
The best video on random forest in R: there is also one on Artificial Neural Network, glm by the same person
Thanks for comments!
I am also using the methods after these tutorials
Thank you very much for giving all the clarity regarding Random Forest.
Can you also give a little bit of explanation on how to analyze spatial data? Thank you in advance!
I've added analysis of spatial data to list of future videos. Thanks!
Great video! Thanks!
Thanks for comments
Great video, thank you!
My pleasure!
This is the best video!!
Thanks for comments!
First class, awesome :)
Thanks for comments!
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
I would suggest you do 2 at a time.
Respected Sir,
I am getting below error while trying to execute "over sampling" in CTG data for multiclass prediction of NSP -
code Over
Great video very very very good
Thank you so much
Thanks for comments!
Awesome; thank you!
Thanks for comments!
quality video.
Magnificent video
Thanks!
Great video, you made random forest clear and easy to understand. Thanks a lot. Would you please make an example on partial least square regression for discrimination and prediction?
Will plan it for future. Thanks!
Great thanks for informative video
Thanks for comments!
very informative sir !
Thanks for comments!
You're the best!!!!!!
