Dynamic Latent Space Modeling of Inhomogeneous Poisson Network Processes with Applications to International Relations
Jie Jian, Jiguo Cao, Owen G. Ward
We study continuous-time relational event data, where time-stamped dyadic interactions reflect both individual node propensities and evolving relational proximity. We propose a dyn…
Functional Attentive Interpretable Regression
Haixu Wang, Tianyu Guan, Jiguo Cao
In function-on-function regression, the coefficient surface may exhibit complex support structure---from localized patches to global patterns such as disconnected regions,…
Estimation of Functional Principal Components from Sparse Functional Data
Uche Mbaka, Jiguo Cao, Michelle Carey
Sparse functional data arise when measurements are observed infrequently and at irregular time points for each subject, often in the presence of measurement error. These characteri…
Learning Data-Efficient and Generalizable Neural Operators via Fundamental Physics Knowledge
Siying Ma, Mehrdad M. Zadeh, Mauricio Soroco +3
Recent advances in scientific machine learning (SciML) have enabled neural operators (NOs) to serve as powerful surrogates for modeling the dynamic evolution of physical systems go…
Locally sparse estimation for simultaneous functional quantile regression
Boyi Hu, Jiguo Cao
Motivated by the study of how daily temperature affects soybean yield, this article proposes a simultaneous functional quantile regression (FQR) model featuring a locally sparse bi…
