Convolutional generative adversarial imputation networks for spatio-temporal missing data in storm surge simulations
Ehsan Adeli, Jize Zhang, Alexandros A. Taflanidis
Imputation of missing data is a task that plays a vital role in a number of engineering and science applications. Often such missing data arise in experimental observations from li…
A Deep Learning-Accelerated Data Assimilation and Forecasting Workflow for Commercial-Scale Geologic Carbon Storage
Hewei Tang, Pengcheng Fu, Christopher S. Sherman +6
Fast assimilation of monitoring data to update forecasts of pressure buildup and carbon dioxide (CO2) plume migration under geologic uncertainties is a challenging problem in geolo…
Offline state estimation for hybrid systems via nonsmooth variable projection
Jize Zhang, Andrew M. Pace, Samuel A. Burden +1
A hybrid dynamical system switches between dynamic regimes at time- or state-triggered events. We propose an offline algorithm that simultaneously estimates discrete and continuous…
Bounded Regression with Gaussian Process Projection
Jize Zhang, Lizhen Lin
Examples with bound information on the regression function and density abound in many real applications. We propose a novel approach for estimating such functions by incorporating…
A Relaxed Optimization Approach for Cardinality-Constrained Portfolio Optimization
Jize Zhang, Tim Leung, Aleksandr Aravkin
A cardinality-constrained portfolio caps the number of stocks to be traded across and within groups or sectors. These limitations arise from real-world scenarios faced by fund mana…
Mean Reverting Portfolios via Penalized OU-Likelihood Estimation
Jize Zhang, Tim Leung, Aleksandr Y. Aravkin
We study an optimization-based approach to con- struct a mean-reverting portfolio of assets. Our objectives are threefold: (1) design a portfolio that is well-represented by an Orn…
