Random Forest Algorithm Clearly Explained!

[@noahrubin375]

Easily the best video on Random Forests I've seen

[@NormalizedNerd]

Thank you!!

[@sidchatt]

Not only a very well-explained video, but aesthetically superb too; the diagrams, the music when the trees are being created - brilliant video! Well done!

[@smitm.1342]

Unbelievable clarity and simplicity. Hallmark of someone who has truly understood in depth and genuinely wishes to share😊

[@yashmore3525]

Hey, I really like the fact that you tend to justify why certain concepts are used the way they are! Hoping to see more fundamental machine learning concepts covered in the future!

[@NormalizedNerd]

That's exactly my goal!

[@red-bluelife]

Exactly!

[@raphaellaoun2784]

I totally agree really helpful, thank you for the nice videos

[@ismail3721]

Awesome video! You explained the concept so much better than many university lectures. I would just like to make a quick point about the random feature selection step when bootstrapping. (imho) According to most recent/popular papers on random forest algorithms, the most common and efficient approach appears to randomly select feature subsets at each node when traversing each tree rather than selecting it only once at the tree level. One explanation I found online is that "while sampling features at every node still allows the trees to see most variables (in different orders) and learn complex interactions, using a subsample for every tree greatly limits the amount of information that a single tree can learn. This means that trees grown in this fashion are going to be less deep, and with much higher bias, in particular for complex datasets. On the other hand, it is true that trees built this way will tend to be less correlated to each other, as they are often built on completely different subsets of features, but in most scenarios, this will not outweigh the increase in bias, therefore, giving a worse performance on most use cases." I really hope this was clear. Any comments are very welcome!

I've done a few machine learning courses on KZbin and LinkedIn and none of them give a good explanation for bagging and I struggled with why and how you would logically aggregate over many models with different parameters and the feasibility of the application of such models. After watching this, I see a clearer picture. Thank you I've been normalized ;)

[@Mutual_Information]

As someone who makes videos on machine learning, I'll say this is an excellent explanation. I like how the algorithm is explained verbally with a visual example. Also, you explain the motivation for the choices of algorithm as you come across them. Variance reduction is key! Very nice - keep it up!

[@NormalizedNerd]

Thanks mate! 😄 I just watched your distribution video and enjoyed it a lot...great work!

[@Mutual_Information]

@@NormalizedNerd Thank you! Much appreciated :)

[@shivoham5939]

variance can be reduced by increasing the no of estimators or trees and by decreasing the no of row sample and column samples for each tree

[@yd3021]

I had no idea about what is random forrest before watching it. This 8 minuts talk helped me alot! Thank you!

[@ericametta6964]

Just came across your channel and i must say you deserve a lot of accolades for how much effort you put into visualizing these concepts and explaining the motivation behind everything so well. Good job really. Not many like you out here

[@tomaszbaczkun8572]

Thank you - that was a really clear explanation! 8 minutes and you made me understand the basics of Random Forest. Crazy.

[@kenshin198406]

Love your animations, they make it so easy to understand. Best that I have seen so far!

[@mohammedarshad9318]

[@saqlainsajid1274]

Man you're really good at explaining things simply and visually love your work

[@MadeleineParnot]

Genuinely the most clear video I've yet to see on Random Forest, I can't believe I finally understand !!

[@richardiovanna1432]

Well done! I've been reading/watching tutorials on this subject ad nauseam for the past week and yours was the first to clearly explain it. Will definitely be watching more of your videos.

[@rose_garden_chess]

Favorite Random forest video yet!! Thank you Normalized Nerd!!

[@NormalizedNerd]

Wow, thanks!

[@NormalizedNerd]

I also think so :P

Thanks man! I know sometimes the courses fail to cover all the details because they have to fit so many things into one semester!

[@fawadafridi3570]

@@NormalizedNerd i dont think syllabus is the reason why would they spent 4 - 5 hrs on random forest then. Its about the technique. However in class teacher cannot focus on every student and also people who search on internet are all dedicated to learn unlike to that of class which is sort of compulsory and you do not get the time of your choice also
