Heavy Tailed Homogeneous Structural Causal Models
Vishal Routh, Shuyang Bai
We consider causal discovery in structural causal models driven by heavy-tailed noise, where extremes carry important information about causal direction. We introduce the Heavy-Tai…

Conditional Independence under Infinite Measures and Poisson Point Processes
Shuyang Bai, Vishal Routh
We study conditional independence under infinite measures on punctured product spaces, a notion recently introduced for graphical modeling in multivariate extremes and Lévy proces…

On estimation and order selection for multivariate extremes via clustering
Shiyuan Deng, He Tang, Shuyang Bai
We investigate the estimation of multivariate extreme models with a discrete spectral measure using spherical clustering techniques. The primary contribution involves devising a me…
