WebOne answer is provided by minimax theory which is a set of techniques for finding the minimum, worst case behavior of a procedure. We provide upper and lower bounds on … Weblower bound the minimax risk in terms of f-divergences other than total variation as well as follows: Using Le Cam’s method, we can nd a bound using total variation and then replace total variation with other f-divergences like ˜2 or hellinger distance. We can also use some other f-divergence directly instead of using total variation.

Webseries of minimax calculations for different sample sizes. There is no initial advantage in making the dependence on the sample size explicit. Consider then the problem of finding a lower bound for the minimax risk R(θ,P) = sup P∈P PL(θ(≤),θ(P)). The behaviour of the loss function enters the minimax problem through the constants c(θ0 ... Web4 does not a ect the minimax convergence rate. Secondly, we adapt the \pseudolabel" method (Car-mon et al., 2024) so that adversarial training achieves the minimax lower bound in classi cation. We gure out the minimax lower bound of the convergence with the presence of unlabeled data (i.e., S 1 to S 4) and pro- mariavallejopsico
