WHOMP: Optimizing Randomized Controlled Trials via Wasserstein Homogeneity
Shizhou Xu, Thomas Strohmer
We investigate methods for partitioning datasets into subgroups that maximize diversity within each subgroup while minimizing dissimilarity across subgroups. We introduce a novel p…
Differentially Private Synthetic High-dimensional Tabular Stream
Girish Kumar, Thomas Strohmer, Roman Vershynin
While differentially private synthetic data generation has been explored extensively in the literature, how to update this data in the future if the underlying private data changes…
Quantum paving: When sphere packings meet Gabor frames
Markus Faulhuber, Thomas Strohmer
We introduce the new problems of quantum packing, quantum covering, and quantum paving. These problems arise naturally when considering an algebra of non-commutative operators that…
Convergence Analysis of the Alternating Anderson-Picard Method for Nonlinear Fixed-point Problems
Xue Feng, M. Paul Laiu, Thomas Strohmer
Anderson Acceleration (AA) has been widely used to solve nonlinear fixed-point problems due to its rapid convergence. This work focuses on a variant of AA in which multiple Picard…
Improving Autoencoder Image Interpolation via Dynamic Optimal Transport
Xue Feng, Thomas Strohmer
Autoencoders are important generative models that, among others, have the ability to interpolate image sequences. However, interpolated images are usually not semantically meaningf…
On the (In)Compatibility between Group Fairness and Individual Fairness
Shizhou Xu, Thomas Strohmer
We study the compatibility between the optimal statistical parity solutions and individual fairness. While individual fairness seeks to treat similar individuals similarly, optimal…
Auto-Calibration and Biconvex Compressive Sensing with Applications to Parallel MRI
Yuan Ni, Thomas Strohmer
We study an auto-calibration problem in which a transform-sparse signal is acquired via compressive sensing by multiple sensors in parallel, but with unknown calibration parameters…
