The Chain Rule is a method for finding complex derivatives and is used all the time in Statistics and Machine Learning. This video breaks it down into its two simple pieces and shows you how they easily come together. We then use the Chain Rule to solve a common Machine Learning problem - optimizing the Residual Squared Loss Function.

0:00 Awesome song and introduction
2:02 A super simple example
6:32 A slightly more complicated example
9:16 The Chain Rule when the relationship is not obvious
11:47 The Chain Rule for the Residual Sum of Squares
Corrections:
13:05 When the residual is negative, the pink circle should be on the left side of the y-axis. And when the residual is positive, the pink circle should be on the right side.

As someone who is doing medical research and needs to learn little-by-little about statistics, neural networks and machine learning as my project goes on, your channel is a literal life-saver! It has been so hard to try to keep my M.D. stuff together with my PhD research all the while learning statistics, programming and neural network structures and machine learning. Trying to arrange courses from my uni to fit in with all the other stuff is simply impossible, so I've been left to my own devices and find a way to gain knowledge about said subjects and your channel has done just that. Your teaching is great and down-to-earth enough to be easily grasped, but you also delve deep into the subject after the initial baby steps, so the person watching isn't just left with "nice to know"-infobits. Love it! Keep up the great work!

Over the past three years, I have been studying neural networks and delving into the world of coding. However, despite my best efforts, I struggled to grasp the true essence of this complex subject. That is until I stumbled upon your enlightening video. I cannot emphasize enough how much your video has helped me. It has shed light on the intricate aspects of neural networks, allowing me to comprehend the subject matter with greater clarity and depth. The way you presented the material was truly remarkable, and it made a profound impact on my understanding. What astounds me even more is that you provide such valuable content for free. It is a testament to your passion for educating and empowering individuals like myself. Your dedication to spreading knowledge and fostering learning is truly commendable. Thanks to your channel, I have been able to unlock the true essence of mathematics and its relationship with neural networks. The confidence and clarity I now have in this subject are invaluable to my personal and professional growth. Your video has been a game-changer for me, and I am grateful beyond words. Please continue your fantastic work and know that your efforts are deeply appreciated.

​@@statquestI know this isn't related to this video, i just want you to help me because you replied to this comment. With gradeint descent, how am i supposed to get the derivative for each weight and bias in a loss function dynamically? because surely for networks with more than 100 neurons there would be a way, i know there is i just don't know. When i am calculating the derivative for one varaible in the loss function, to optimize it, i get some overly complicated function, but i see some papers on it and it isn't complicated.

Hi Josh, thank you for your awesome video as always! Been learning with you for some time now. I really enjoy learning thru your lens, and been curious why you call terminology dreadful :D ? Although the first time exposure is always not easy, terminology is an anchor to me. It keeps me from getting adrift amidst the sea of confusing concepts and ideas. Sometimes teachers and tutors go so fast, so I make sure to ask them if what they are talking about has a name. So I can always read more about it at my pace when I'm lost again. Sharing a bit of my lens. Thank you always ;-) !

13:15 Is the residual(squared) graph mirrored? Since residual=(observed - predicted), wouldn't that mean that when on the original graph the intercept is zero, the residual would be positive(2-1=1), so the position on the residual(squared) graph should be on the positive x-axis(x=1), as opposed to the negative side on the video, and vice versa?

13:27 When the residual is negative, the pink circle is shown to be on the right side of the y-Axis, but shouldn't it be on the left side? Aside from that, great content! Cheers from Germany

Yep. Thanks for catching that! I've added a correction to the pinned comment.

Best reference for learning statistics. Btw, would just like to point out that in 6:16, there appears to be a minor mistake. Actually for every 1 unit increase in Weight, there is a 2 unit increase in Shoe Size, because the equation would be Size = (1/2)*Weight, or 2*Size = 1*Weight

This video is actually correct. For every one unit increase in weight, there is only a 1/2 unit increase in Shoe Size. What your equation shows is that for every unit increase in Size, there is a 2 unit increase Weight. That's not the same thing as "for every unit increase in Weight, there is a 2 unit increase in Size".

@@statquest I calculated through the equation, and you are correct. Thanks for the verification!

Amazing Video. Helps a lot! Does anyone know an example of an empirical research paper in which the chain rule (two step procedure) is applied in the context of empirical testing of the research question/hypothesis? Thank you very much for a reply!

Logistic Regression uses Gradient Descent, which, in turn, often uses the chain rule

​@@statquest Dear Josh, thank you for your answer. I want to concretise my question. I understood from your videos that the chain rule is used in neural networks to solve the optimization problem and also in logistic regression using gradient descent etc.. I'm currently looking for a content example of published research (= a concret study) in which the modelling approach weight (some indepedent variable) predicts height(some other independent variable) and height predicts shoe size(dependent variable). Does anyone know an example of such an empirical research paper? Thank you very much for a reply!
