A Shrinkage Path Heuristic for Wasserstein Distributionally Robust Optimization
Lingjun Meng, Ryan Cory-Wright, Wolfram Wiesemann
Wasserstein distributionally robust optimization (DRO) is a versatile and widely adopted framework for decision-making under uncertainty, yet its standard deterministic reformulati…
msPCA: An R Package for Sparse PCA with Multiple Components
Ryan Cory-Wright, Jean Pauphilet
We present msPCA: an open-source R package for sparse principal component analysis with multiple components. It implements an alternating maximization algorithm to generate a set o…
Compact Lifted Relaxations for Low-Rank Optimization
Ryan Cory-Wright, Jean Pauphilet
We develop tractable convex relaxations for rank-constrained quadratic optimization problems over matrices, a setting for which tractable relaxations are typically onl…
Pricing Discrete and Nonlinear Markets With Semidefinite Relaxations
Cheng Guo, Lauren Henderson, Ryan Cory-Wright +1
Nonconvexities in markets with discrete decisions and nonlinear constraints make efficient pricing challenging, often necessitating subsidies. A prime example is the unit commitmen…
