thank you, can I ask the derivative of d/dA ln(e^(X'A)) vs d/dA (e^(X'A))/(1+e^(X'A))? X' = transpose (X) X and A is matrix because I read a post, that the result d/dA ln (e^(X'...)) = X ... (matrix X not transpose, this is what confuses me). while d/dA (e^(X'...)/...)=X'.../... (transpose matrix X)
Thank you very much professor! I learned a lot from your LA lectures!

vs

X' = transpose (X)
X and A is matrix
because I read a post, that the result
d/dA ln (e^(X'...)) = X ...
(matrix X not transpose, this is what confuses me).

Did you forget to upload this one earlier?
It had been marked as unlisted but still linked to from the previous video- we made it public so it would be easier for folk to find.
