Mitigating distribution shift in machine learning-augmented hybrid simulation

1 code implementation17 Jan 2024 Jiaxi Zhao, Qianxiao Li

We study the problem of distribution shift generally arising in machine-learning augmented hybrid simulation, where parts of simulation algorithms are replaced by data-driven surrogates.

Scaling Limits of the Wasserstein information matrix on Gaussian Mixture Models

no code implementations22 Sep 2023 Wuchen Li, Jiaxi Zhao

We consider the Wasserstein metric on the Gaussian mixture models (GMMs), which is defined as the pullback of the full Wasserstein metric on the space of smooth probability distributions with finite second moment.

SocialVisTUM: An Interactive Visualization Toolkit for Correlated Neural Topic Models on Social Media Opinion Mining

no code implementations RANLP 2021 Gerhard Johann Hagerer, Martin Kirchhoff, Hannah Danner, Robert Pesch, Mainak Ghosh, Archishman Roy, Jiaxi Zhao, Georg Groh

In this paper, we demonstrate how these methods can be used to display correlated topic models on social media texts using SocialVisTUM, our proposed interactive visualization toolkit.

A matter of time: Using dynamics and theory to uncover mechanisms of transcriptional bursting

1 code implementation20 Aug 2020 Nicholas C. Lammers, Yang Joon Kim, Jiaxi Zhao, Hernan G. Garcia

Eukaryotic transcription generally occurs in bursts of activity lasting minutes to hours; however, state-of-the-art measurements have revealed that many of the molecular processes that underlie bursting, such as transcription factor binding to DNA, unfold on timescales of seconds.
