Conditional Pseudo-Reversible Normalizing Flow for Surrogate Modeling in Quantifying Uncertainty Propagation

1 code implementation31 Mar 2024 Minglei Yang, Pengjun Wang, Ming Fan, Dan Lu, Yanzhao Cao, Guannan Zhang

We introduce a conditional pseudo-reversible normalizing flow for constructing surrogate models of a physical model polluted by additive noise to efficiently quantify forward and inverse uncertainty propagation.

Diffusion-Model-Assisted Supervised Learning of Generative Models for Density Estimation

no code implementations22 Oct 2023 Yanfang Liu, Minglei Yang, Zezhong Zhang, Feng Bao, Yanzhao Cao, Guannan Zhang

Unlike existing diffusion models that train neural networks to learn the score function, we develop a training-free score estimation method.

Convergence Analysis for Training Stochastic Neural Networks via Stochastic Gradient Descent

1 code implementation17 Dec 2022 Richard Archibald, Feng Bao, Yanzhao Cao, Hui Sun

In this paper, we carry out numerical analysis to prove convergence of a novel sample-wise back-propagation method for training a class of stochastic neural networks (SNNs).

A Backward SDE Method for Uncertainty Quantification in Deep Learning

no code implementations28 Nov 2020 Richard Archibald, Feng Bao, Yanzhao Cao, He Zhang

We develop a probabilistic machine learning method, which formulates a class of stochastic neural networks by a stochastic optimal control problem.
