Renormalizing Diffusion Models

no code implementations23 Aug 2023 Jordan Cotler, Semon Rezchikov

We explain how to use diffusion models to learn inverse renormalization group flows of statistical and quantum field theories.

Light Field Networks: Neural Scene Representations with Single-Evaluation Rendering

1 code implementation NeurIPS 2021 Vincent Sitzmann, Semon Rezchikov, William T. Freeman, Joshua B. Tenenbaum, Fredo Durand

In this work, we propose a novel neural scene representation, Light Field Networks or LFNs, which represent both geometry and appearance of the underlying 3D scene in a 360-degree, four-dimensional light field parameterized via a neural implicit representation.

Stochastic natural gradient descent draws posterior samples in function space

no code implementations25 Jun 2018 Samuel L. Smith, Daniel Duckworth, Semon Rezchikov, Quoc V. Le, Jascha Sohl-Dickstein

Recent work has argued that stochastic gradient descent can approximate the Bayesian uncertainty in model parameters near local minima.
