Bayesian Non-linear Latent Variable Modeling via Random Fourier Features

1 code implementation14 Jun 2023 Michael Minyi Zhang, Gregory W. Gundersen, Barbara E. Engelhardt

The Gaussian process latent variable model (GPLVM) is a popular probabilistic method used for nonlinear dimension reduction, matrix factorization, and state-space modeling.

Active multi-fidelity Bayesian online changepoint detection

1 code implementation26 Mar 2021 Gregory W. Gundersen, Diana Cai, Chuteng Zhou, Barbara E. Engelhardt, Ryan P. Adams

We propose a multi-fidelity approach that makes cost-sensitive decisions about which data fidelity to collect based on maximizing information gain with respect to changepoints.

Latent variable modeling with random features

2 code implementations19 Jun 2020 Gregory W. Gundersen, Michael Minyi Zhang, Barbara E. Engelhardt

By approximating a nonlinear relationship between the latent space and the observations with a function that is linear with respect to random features, we induce closed-form gradients of the posterior distribution with respect to the latent variable.
