Inferring Manifolds From Noisy Data Using Gaussian Processes

1 code implementation14 Oct 2021 David B Dunson, Nan Wu

In analyzing complex datasets, it is often of interest to infer lower dimensional structure underlying the higher dimensional observations.

Graph Based Gaussian Processes on Restricted Domains

no code implementations14 Oct 2020 David B Dunson, Hau-Tieng Wu, Nan Wu

The GL is constructed from a kernel which depends only on the Euclidean coordinates of the inputs.

Estimating densities with nonlinear support using Fisher-Gaussian kernels

1 code implementation12 Jul 2019 Minerva Mukhopadhyay, Didong Li, David B Dunson

We provide theory on large support, and illustrate gains relative to competitors in simulated and real data applications.

Targeted stochastic gradient Markov chain Monte Carlo for hidden Markov models with rare latent states

no code implementations31 Oct 2018 Rihui Ou, Deborshee Sen, Alexander L Young, David B Dunson

We propose a targeted sub-sampling (TASS) approach that over-samples observations corresponding to rare latent states when calculating the stochastic gradient of parameters associated with them.
