WebA stochastic projected Wasserstein gradient flow that keeps track of the belief of the estimated quantity and can consume samples from online data is devised, enabling, among others, improved robustness for decision-making. We study estimation problems in safety-critical applications with streaming data. Since estimation problems can be posed as … WebSOUPy is built on the open-source hIPPYlib library, which provides state-of-the-art scalable adjoint-based methods for deterministic and Bayesian inverse problems governed by PDEs, which in turn makes use of the FEniCS library for high-level formulation, discretization, and scalable solution of PDEs.
Orthogonal Estimation of Wasserstein Distances - University …
WebFeb 13, 2024 · We propose the projected error function regularization loss (PER) that encourages activations to follow the standard normal distribution. PER randomly projects activations onto one-dimensional space and computes the regularization loss in the projected space. WebDec 31, 2024 · Optimizing the Gromov-Wasserstein distance with PyTorch ===== In this example, we use the pytorch backend to optimize the Gromov-Wasserstein (GW) loss between two graphs expressed as empirical distribution. In the first part, we optimize the weights on the node of a simple template: graph so that it minimizes the GW with a given … date full moon party 2023
Two-sample Test using Projected Wasserstein Distance
Webprojected Wasserstein distance as the test statistic, i.e., the test statistic works by finding the linear projector such that the distance between projected distributions is maximized. … WebStrengths: (1) Computing the projected Wasserstein distance is an important topic in OT and ML. While previous work focuses on the statistical properties and convex relaxation of the projection robust Wasserstein distance, this paper considers a direct approach by solving a max-min formulation.
