Second, we identify a nice local region with no local-min or saddle points. Nevertheless, it is not clear whether gradient descent can stay in this nice re-gion. Third, we consider a constrained optimization formulation where the feasible poros formation

"Witryna1. Introduction. In recent years the gradient flow has attracted much attention for practical and conceptual reasons [1– 7].Practically, as shown by Lüscher and Weisz [2, 3], the gradient flow in non-Abelian gauge theory does not induce extra UV divergences in the bulk, so that the bulk theory is finite once the boundary theory is properly … " - Improves expressivity and gradient flow
