Understanding Backpropagation In Neural Networks with Basic Calculus

[@Slim]

Spent the past weeks trying to grasp backpropagation mathematically. Spent countless days on videos and textbooks. This is by far the most intuitive explanation. Just subbed. Thank you.

I am glad this was helpful and thank you for subscribing.

Thank you again! This was incredibly simple to understand and exactly what I was looking for.

Very helpful

at 12:18 at the bottom right corner i think the matrix with the xs should be a 1 x 3 matrix and not a 3x1 matrix, otherwise the matrix multiplication wont work

[@DrDataScience]

Both vectors x and w are 3x1. Note that we are using the transpose of W, which means that the result would be (1 x 3) x (3 x1), which is scalar.

Can you explain about optimizer state

[@llothar68]

Do i need to understand all this to use neural networks? I'm scared shitless but my curiculuum says i have to learn it

[@leonmark2416]

the best session tha i can recommend to anyone. I studied computer science and i am not good at math and this was really a saver to coninue on.

[@polycarpnalela2297]

Thanks!! It was very useful

[@DrDataScience]

Thanks!

Can you please do a video on different cross validation techniques in machine learning

[@DrDataScience]

Great suggestion, thanks!

What is phi with a1? Is it activation function.?

[@hieuluc8888]

I couldn't really understand what a computational graph was until I watched this video. Thank you very much.

[@DrDataScience]

Thank you!

[@Fantastics_Beats]

I love you brother your teaching

[@parisahajibabaee2893]

You can present complex information in simplified manner, many thanks!

[@omnnnooy3267]

I cannot express how thankful I'm !

thanks for meaningful describe

[@DrDataScience]

Thank you!

[@esper5429]

The only video that explained me everything

[@DrDataScience]

Thank you so much!
