Faster than Fast-LTS: Robust Regression and Outlier Detection with DC Programming
Marah-Lisanne Thormann, Phan Tu Vuong, Alain B. Zemkoho +1
When datasets contain outliers, robust regression is a well-established alternative to Ordinary Least Squares. A commonly employed robust estimator is Least Trimmed Squares (LTS),…

Bilevel learning refers to machine learning problems that can be formulated as bilevel optimization models, where decisions are organized in a hierarchical structure. This paradigm…
Box Allocation Optimization in Meal Kit Delivery
Thi Minh Thu Nguyen, Loic Genest, Alain Zemkoho
This study introduces the Box Allocation Problem (BAP), a novel optimization challenge in the $1.4 billion UK meal kit delivery market. BAP involves assigning orders across multipl…
Achieving Better Regret against Strategic Adversaries
Le Cong Dinh, Tri-Dung Nguyen, Alain Zemkoho +1
We study online learning problems in which the learner has extra knowledge about the adversary's behaviour, i.e., in game-theoretic settings where opponents typically follow some n…
