Non-KKT Accumulation in Entropic Mirror Descent
The episode discusses a paper titled "Non-KKT Accumulation in Entropic Mirror Descent" by Ding and Toh. The hosts explain how this paper provides a concrete counterexample showing that mirror descent can converge to points that do not satisfy KKT conditions. They conclude that this result challenges existing convergence theories and suggests future research should focus on structural properties of objectives or kernels to prevent this boundary behavior.
