Witryna3 Computing Wasserstein Gradient Flows with ICNNs We now describe our approach to compute Wasserstein gradient flows via JKO stepping with ICNNs. 3.1 JKO Reformulation via Optimal Push-forwards Maps Our key idea is to replace the optimization (6) over probability measures by an optimization over convex functions, … Witryna10 maj 2024 · Optimization is at the heart of machine learning, statistics, and many applied scientific disciplines. It also has a long history in physics, ranging from the minimal action principle to finding ground states of disordered systems such as spin glasses. Proximal algorithms form a class of methods that are broadly applicable and …

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 …
Witrynaexpressivity is strong, i.e., there exists at least one global minimizer with zero training loss. 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

Furthermore, the new point of view shows that our geometric element transformation untangles the individual volume elements (see section 6) and regularizes them (see section 7). 3.
