Hello, \(\displaystyle w, w^T, w_x, w_y\) are vectors of same dimensions
\(\displaystyle (w^Tw_x-w^Tw_y)^2=w^T(w_x-w_y)(w_x-w_y)^Tw\)
I dont understand where the right \(\displaystyle w\) comes from.
I do:
\(\displaystyle
(w^Tw_x-w^Tw_y)^2 = (w^Tw_x-w^Tw_y)(w^Tw_x-w^Tw_y)^T = ?\) here I would do \(\displaystyle w^T(w_x-w_y)w^T(w_x-w_y)^T\) but its not correct
thx
