I have seen this a lot in my ML classes, and I wanted some clarification.
In vector calculus, what are the conventions for the shape of the gradients?
For example, here the gradient of a row vector u^T is a column vector v. Do the columns represents del f/... and the rows represent .../del u_i?
Quick question!
