  Just another quick question about this part: The first term is $\frac{\partial \ell }{\partial z_9}=\frac{\partial (y-z_9{)}^2}{\partial z_9}=2z_9$.

  Shouldn’t this be: $\frac{\partial (y-z_9{)}^2}{\partial z_9}=-2(y-z_9)$?

  You mentioned just after something about notation, but I wanted to understand a bit better in case I’m missing something

  Cool, thanks a lot. I assumed the notation was right.

  Thanks for the post, by the way, really great work.

  Just wondering, you refer to the derivative here but the notation is for the partial derivative, which one is correct?
