Resource Allocation under Stochastic Demands using Shrinking Horizon Optimization

Alexandros E. Tzikas, Nazim Kemal Ure, Mansur Arief +2

We consider the problem of optimally allocating a limited number of resources across time to maximize revenue under stochastic demands. This formulation is relevant in various area…

Distributionally Robust Control with Constraints on Linear Unidimensional Projections

Alexandros E. Tzikas, Lukas Fiechtner, Arec Jamgochian +1

Distributionally robust control is a well-studied framework for optimal decision making under uncertainty, with the objective of minimizing an expected cost function over control a…

An Iterative Bayesian Approach for System Identification based on Linear Gaussian Models

Alexandros E. Tzikas, Mykel J. Kochenderfer

We tackle the problem of system identification, where we select inputs, observe the corresponding outputs from the true system, and optimize the parameters of our model to best fit…

Enhanced Importance Sampling through Latent Space Exploration in Normalizing Flows

Liam A. Kruse, Alexandros E. Tzikas, Harrison Delecki +2

Importance sampling is a rare event simulation technique used in Monte Carlo simulations to bias the sampling distribution towards the rare event of interest. By assigning appropri…

Sliced Distribution Matching based on Cumulative Distribution Functions with Applications to Control

Alexandros E. Tzikas, Arec Jamgochian, Nazim Kemal Ure +2

Computing the similarity between two probability distributions is a recurring theme across control. We introduce a unified family of distances between the probability distributions…
