Hi All
New to the forum. I am in the process of learning about backpropagation for use in AI. My maths is very rusty and i am stuck at intuitively understanding the chain rule. I have designed a spreadsheet as to confirm my understanding of how the chain rule works with multi-variable functions.
There is a function Z which is dependent on X and Y where X and Y are dependent on N. I want to know the following: If i make a small change to N how much will this affect the output of function Z. I get to an answer but this does not correspond to change in the output of Z when i actually make a small change to N. See below image of spreadsheet.
