CS231n assignment3 inline question1 GAN part

문제 : We will look at an example to see why alternating minimization of the same objective (like in a GAN) can be tricky business. Consider c(c,c)=ccf(x,y)=xy . What does mincmaxcc(c,c)minxmaxyf(x,y) evaluate to? (Hint: minmax tries to minimize the maximum value achievable.) Now try to evaluate this function numerically for 6 steps, starting at the point (1,1)(1,1) , by using alternating gradient (first updating y, then updating x using that updated y) with step size 11 . Here step size is the le...
