WebMay 22, 2024 · “Differentiation rules” can be developed that allow us to compute all the partial derivatives at once, taking advantage of the matrix forms of the functions. As you will see, these rules are mostly ‘organizational’ and seldom go beyond differentiation of linear expressions or squares. We cover here only the most basic ones. http://www.gatsby.ucl.ac.uk/teaching/courses/sntn/sntn-2024/resources/Matrix_derivatives_cribsheet.pdf
Webthe derivative of one vector y with respect to another vector x is a matrix whose (i;j)thelement is @y(j)=@x(i). such a derivative should be written as @yT=@x in which case it is the Jacobian matrix of y wrt x. its determinant represents the ratio of the hypervolume dy to that of dx so that R R f(y)dy = f(y(x))j@yT=@xjdx. however, the sloppy …
