Autocorrelated Optimize-via-Estimate: Predict-then-Optimize versus Finite-sample Optimal

Zichun Wang, Gar Goei Loke, Ruiting Zuo

Models that directly optimize for out-of-sample performance in the finite-sample regime have emerged as a promising alternative to traditional estimate-then-optimize approaches in…

From Continuous to Discrete: a No-U-Turn Sampler for Permutations

Nawaf Bou-Rabee, Zichu Wang

We introduce a discrete-space analogue of the No-U-Turn sampler on the symmetric group , yielding a locally adaptive and reversible Markov chain Monte Carlo method for $\mathr…

Nonholonomic Narrow Dead-End Escape with Deep Reinforcement Learning

Denghan Xiong, Yanzhe Zhao, Yutong Chen +1

Nonholonomic constraints restrict feasible velocities without reducing configuration-space dimension, which makes collision-free geometric paths generally non-executable for car-li…

Optimal transport with a density-dependent cost function

Zichu Wang, Esteban G. Tabak

A new pairwise cost function is proposed for the optimal transport barycenter problem, adopting the form of the minimal action between two points, with a Lagrangian that takes into…
