Essential Matrix Algebra for Neural Networks, Clearly Explained!!!

Although you don't need to know matrix algebra to understand the ideas behind neural networks, if you want to code them or read the latest manuscripts about the field, then you'll need to understand matrix algebra. This video teaches the essential topics in matrix algebra and shows how a neural network can be written as a matrix equation, and then shows how understand PyTorch documentation, error messages and the equations for Attention, which is the fundamental concept behind ChatGPT.

Note: If you want to learn more about neural networks...
...backpropagation...
...the ReLU activation function...
...tensors...
...SoftMax...
...Transformers and Attention...

All visual learners are blessed by the great Josh Starmer!

What you do is nothing short of a miracle! Immense gratitude

Could you please make a video about QLORA? ❤ You're our savior when it comes to understanding complex concepts, thank you man

I found this channel when searching for a clear explanation of central limit theorem on Google (after doing some simulation in R using sample size much less than 30 and being intrigued by the results I got) and I just want to say I love the content so much! (And the ukulele episode ❤) I’ve recently started some machine learning classes on coursera and EdX, and I must say the explanation you have here in these episodes are SO MUCH BETTER AND MORE TO THE POINT/BETTER DEFINED than the multi thousand dollar classes (I’m surely glad I chose to audit them first!) taught by professors from Harvard or Engineers working for Google/IBM. So much better!… ❤❤❤

Just want to say thank you and Merry Christmas! I know I will be going through these videos one by one in the coming months…

I was thinking about taking a course to learn matrix algebra yesterday. Thanks for posting this video. It is really helpful and it is like a wish came true.

Hi Josh... would you please make a video and explain the differences between different statistical tests like t, z, chi... I want to know the differences and when to use each.

[yurobert]

Crisp and clear explanation on matrix multiplication in the context of neural networks. Moreover, the quality of graphics/visual presentation is impeccable!

[백영래-ux]

You have been staying the course for a long, long time. It's not so easy ! Keep up the good work!

[ShadArfMohammed]

Baaam this is good :D I have been waiting for this, to be honest, I had the feeling that one day you would make such a tutorial. Your content is great.

[louisnemzer]

Squatch: So it's all just matrix multiplication?

Josh: Always has been

[ageofkz]

Really amazing work! This set of videos (neural network playlist) has really helped me in my uni coursework and project! My groupmates and I are planning to get a statquest triple bam hoodie each haha!

[haitematik]

Man u deserve a thousand times more subscribers

[anmolarora]

Thank you for explaining it so simply even a novice like me can understand it.

[varshinibalaji]

Wow, just the perfect video I was looking for! Loved all the Taylor references, and music puns.

[randr]

Thank you for this video. I think I understand what a transformer is now.

[michaelzap]

Best of the best. I'm really speechless now.

[techproductowner]

You will be known and remembered for the next 1000 years ..

[kujohjotaro]

Your video is just a lifesaver to me and my essay! Could you make a video on the Glove model in NLP?

[NJCLM]

Very good video ! You should remake one of the transformer videos with the matrix notation as you done at the end of this vide.
