Semi-supervised Learning of Pushforwards For Domain Translation & Adaptation

no code implementations18 Apr 2023 Nishant Panda, Natalie Klein, Dominic Yang, Patrick Gasda, Diane Oyen

We compare our method (parOT) to related optimal transport approaches in the context of domain adaptation and domain translation on benchmark data sets.

Domain Adaptation Translation

Generative structured normalizing flow Gaussian processes applied to spectroscopic data

no code implementations14 Dec 2022 Natalie Klein, Nishant Panda, Patrick Gasda, Diane Oyen

In particular, in the physical sciences, limited training data may not adequately characterize future observed data; it is critical that models adequately indicate uncertainty, particularly when they may be asked to extrapolate.

Denoising neural networks for magnetic resonance spectroscopy

no code implementations31 Oct 2022 Natalie Klein, Amber J. Day, Harris Mason, Michael W. Malone, Sinead A. Williamson

Our motivating example is magnetic resonance spectroscopy, in which a primary goal is to detect the presence of short-duration, low-amplitude radio frequency signals that are often obscured by strong interference that can be difficult to separate from the signal using traditional methods.

Torus Graphs for Multivariate Phase Coupling Analysis

1 code implementation24 Oct 2019 Natalie Klein, Josue Orellana, Scott Brincat, Earl K. Miller, Robert E. Kass

Angular measurements are often modeled as circular random variables, where there are natural circular analogues of moments, including correlation.
