ADAPTIVE FLOW MATCHING FOR RESOLVING SMALL-SCALE PHYSICS

Abstract

Apparatuses, systems, and techniques for adaptive flow matching. In at least one embodiment, input is received, which includes one or more first variables at first scale. An encoder is used to encode the input to provide a base distribution at the first scale. The base distribution is associated with one or more second variables, and the one or more second variables include one or more variables absent from the one or more first variables. A perturbed base distribution is obtained based on the base distribution and an adaptive noise. A diffusion model is used to generate a target distribution at a second scale. The target distribution is associated with the one or more second variables. The second scale is finer than the first scale.
