Universal Functional Regression with Neural Operator Flows

no code implementations3 Apr 2024 Yaozhong Shi, Angela F. Gao, Zachary E. Ross, Kamyar Azizzadenesheli

We empirically study the performance of OpFlow on regression and generation tasks with data generated from Gaussian processes with known posterior forms and non-Gaussian processes, as well as real-world earthquake seismograms with an unknown closed-form distribution.

Discovering Structure From Corruption for Unsupervised Image Reconstruction

no code implementations12 Apr 2023 Oscar Leong, Angela F. Gao, He Sun, Katherine L. Bouman

We show that such a set of inverse problems can be solved simultaneously without the use of a spatial image prior by instead inferring a shared image generator with a low-dimensional latent space.

Image Reconstruction without Explicit Priors

no code implementations21 Mar 2023 Angela F. Gao, Oscar Leong, He Sun, Katherine L. Bouman

We show that such a set of inverse problems can be solved simultaneously by learning a shared image generator with a low-dimensional latent space.

Seismic wave propagation and inversion with Neural Operators

no code implementations11 Aug 2021 Yan Yang, Angela F. Gao, Jorge C. Castellanos, Zachary E. Ross, Kamyar Azizzadenesheli, Robert W. Clayton

We develop a scheme to train Neural Operators on an ensemble of simulations performed with random velocity models and source locations.

Generalized Unsupervised Clustering of Hyperspectral Images of Geological Targets in the Near Infrared

1 code implementation24 Jun 2021 Angela F. Gao, Brandon Rasmussen, Peter Kulits, Eva L. Scheller, Rebecca Greenberger, Bethany L. Ehlmann

The application of infrared hyperspectral imagery to geological problems is becoming more popular as data become more accessible and cost-effective.
