NOTE: Gradient Boost usually uses regression trees. These are very similar to classification trees, but have a slightly different way to decide how to add branches and leaves.

Hey your channel is a saviour for me because you make all complicated concepts easy to understand . Thanks for contributing the datascience community with such great content
I was scratching my head for 2 days to understand the GB algorithm and all the sites and resources on the internet are quite confusing. You just explained it so clearly and BAM...you got a new subscriber!
Holy shit, I was able to finish my assignment in 1 night while watching this. For the past 1-2 weeks I'm doing an all-nighter and pulling my hair to finish my assignment using the notes I have from my class.
Thanks for your hard work producing all these incredible tutorials Josh. I just can't imagine how'd I have learned these concepts otherwise without your videos!
Loved your videos, man! It's actually makes it's easy to understand the concepts behind the models instead of trying to read their papers, which can take time and some times can be really hard .
Hi Josh, this is by far, the clearest explanation for a concept I was try to figure out for 3 months. Thank you very much! really appreciate your effort ! Keep up the good work !
Same here. For more than a year, I have been using Gradient Boosting heavily because of its accuracy, without understanding how it works. Now all is clear to me. Thank you, StatQuest!!!!!!!!!!!!!!!!!
thanks for another amazing vid. watching this video alone improves my understanding not only about the model, but also about hyperparameters which makes me better at ML modelling. lucky to have you in the community.
Salut Josh et merci! (Just a french person trying to show his gratitude). Man, your method is amazing and you have a good voice. I saved your videos and locked them in a safe for when my 5 y old daughters are ready to hear about stats and ML... Precious gift you've got. Au revoir!
Thank you! Very few people watch the summaries (youtube gives me statistics that tell me when people stop watching) so I've been debating whether or not they are worth the effort. It's good to know that you appreciate them.
This is some godlike storytelling, I know myself sometimes skipped/half-understand the mathematical reasoning behind every algorithm, because sometimes its unbearable, too mathematical. You get the essence and storytelling it perfectly! Thanks man! Tha'ts a subs and bell for you!
great material, thank you :) sometimes, we need to relax, take a step back and look at seemingly complicated things with a simple perspective. I hope more teachers are exposed to this kind of freedom and agility to creatively present their lessons.
Hi Josh, I am a Data Scientist and a music enthusiast (drummer). This video has cleared a long time confusion of mine. Thanks a lot buddy. Your songs are also good. :) Keep Rocking.
This man saves my life. I first tried to understand the one by reading the book: Elements of Statistical Learning, the book is too complicated and too much information for beginners. I think it's better approach to learn the cores with the visualization first, just like this video, and mathematical properties then next. Looking forward to watching the next video! Right away!
I found boosting conceptually harder to grasp than bagging and random forest. This video explains each step with nice clear graphics with just about right pace! Thanks for the great efforts you have put into making this brilliant work.
People who doesn't like his videos ... are with no BAM! please guys who watch his videos do like it .. least you can contribute and you know how much it takes to make such videos ...just go through refrence and read it
I was working on this all day, because most examples on the internet only touch the classification side of tree-based models. And now my Messiah, my saviour. StatQuest is the only true way of living and all infidels shall be doomed to misinterpret data for the rest of their mortal existence.
