Bayesian Conditional Diffusion Models for Versatile Spatiotemporal Turbulence Generation

no code implementations14 Nov 2023 Han Gao, Xu Han, Xiantao Fan, Luning Sun, Li-Ping Liu, Lian Duan, Jian-Xun Wang

A notable feature of our approach is the method proposed for long-span flow sequence generation, which is based on autoregressive gradient-based conditional sampling, eliminating the need for cumbersome retraining processes.

Evaluating General-Purpose AI with Psychometrics

Bayesian Spline Learning for Equation Discovery of Nonlinear Dynamics with Quantified Uncertainty

1 code implementation14 Oct 2022 Luning Sun, Daniel Zhengyu Huang, Hao Sun, Jian-Xun Wang

The equation residuals are used to inform the spline learning in a Bayesian manner, where approximate Bayesian uncertainty calibration techniques are employed to approximate posterior distributions of the trainable parameters.

Mental health concerns prelude the Great Resignation: Evidence from Social Media

no code implementations16 Aug 2022 R. Maria del Rio-Chanona, Alejandro Hermida-Carrillo, Melody Sepahpour-Fard, Luning Sun, Renata Topinkova, Ljubica Nedelkoska

To study the causes of the 2021 Great Resignation, we use text analysis to investigate the changes in work- and quit-related posts between 2018 and 2021 on Reddit.
