From Nonsmooth Minima to Smooth Branches via Heat Kernel Regularization
Hyeontae Jo
Many optimization problems in science and engineering involve objective functions that are nonsmooth at their minimizers. A common strategy is to trace a branch of minimizers of a…

Estimation of System Parameters Including Repeated Cross-Sectional Data through Emulator-Informed Deep Generative Model
Hyunwoo Cho, Sung Woong Cho, Hyeontae Jo +1
Differential equations (DEs) are crucial for modeling the evolution of natural or engineered systems. Traditionally, the parameters in DEs are adjusted to fit data from system obse…
