Multifidelity Computer Model Emulation Via Diffusion Model Steering and Targeted Maximum Likelihood
Jongmin Mun
We develop a multifidelity method for fusing low-resolution simulations with computationally expensive high-resolution simulations, which are run infrequently and are therefore pro…
Hybrid Partial Least Squares Regression with Multiple Functional and Scalar Predictors
Jongmin Mun, Jeong Hoon Jang
Motivated by renal imaging studies that combine renogram curves with pharmacokinetic and demographic covariates, we propose Hybrid partial least squares (Hybrid PLS) for simultaneo…
Iterative Exploration-Driven Sparse SDP Clustering via Thompson Sampling
Jongmin Mun, Paromita Dubey, Yingying Fan
High-dimensional sparse clustering is a challenging combinatorial problem due to the tight coupling between cluster assignment and variable selection. We demonstrate that semidefin…
Minimax Optimal Two-Sample Testing under Local Differential Privacy
Jongmin Mun, Seungwoo Kwak, Ilmun Kim
We explore the trade-off between privacy and statistical utility in private two-sample testing under local differential privacy (LDP) for both multinomial and continuous data. We b…
