Although optimization methods are at the core of ML, recent advances have mostly focused on unconstrained convex optimization. However, as mentioned earlier, many engineering applications feature combinatorial and highly constrained settings. Combinatorial optimization and MIP have yet to be used systematically in ML but have the potential to improve generalization and interpretability. The thrust will develop novel ML methods for constrained learning based on combinatorial optimization.

Meta-Algorithms Research Group

The goal of the meta algorithms research group is to develop automatic algorithm/model selection for optimization problems or for machine learning tasks.
