On Estimating the Gradient of the Expected Information Gain in Bayesian Experimental Design

1 code implementation19 Aug 2023 Ziqiao Ao, Jinglai Li

The gradient information is often needed for efficient EIG optimization, and as a result the ability to estimate the gradient of EIG is essential for BED problems.

Deep Unrolling Networks with Recurrent Momentum Acceleration for Nonlinear Inverse Problems

1 code implementation30 Jul 2023 Qingping Zhou, Jiayu Qian, Junqi Tang, Jinglai Li

We provide experimental results on two nonlinear inverse problems: a nonlinear deconvolution problem, and an electrical impedance tomography problem with limited boundary measurements.

NF-ULA: Langevin Monte Carlo with Normalizing Flow Prior for Imaging Inverse Problems

1 code implementation17 Apr 2023 Ziruo Cai, Junqi Tang, Subhadip Mukherjee, Jinglai Li, Carola Bibiane Schönlieb, Xiaoqun Zhang

Bayesian methods for solving inverse problems are a powerful alternative to classical methods since the Bayesian approach offers the ability to quantify the uncertainty in the solution.

Predicting the behaviors of pedestrian crowds is of critical importance for a variety of real-world problems.

Affine-Mapping based Variational Ensemble Kalman Filter

no code implementations10 Mar 2021 Linjie Wen, Jinglai Li

We propose an affine-mapping based variational Ensemble Kalman filter for sequential Bayesian filtering problems with generic observation models.

An approximate KLD based experimental design for models with intractable likelihoods

1 code implementation1 Apr 2020 Ziqiao Ao, Jinglai Li

Data collection is a critical step in statistical inference and data science, and the goal of statistical experimental design (ED) is to find the data collection setup that can provide most information for the inference.

Bayesian inverse regression for dimension reduction with small datasets

no code implementations19 Jun 2019 Xin Cai, Guang Lin, Jinglai Li

We consider supervised dimension reduction problems, namely to identify a low dimensional projection of the predictors $\-x$ which can retain the statistical relationship between $\-x$ and the response variable $y$.

Adaptive Gaussian process approximation for Bayesian inference with expensive likelihood functions

1 code implementation29 Mar 2017 Hongqiao Wang, Jinglai Li

In particular, we write the joint density approximately as a product of an approximate posterior density and an exponentiated GP surrogate.
