Summary

research-semester-programme-g

This semester programme aims to combine optimization and machine learning, in order to develop data-centric methods attaining both performance guarantees and explainability. This includes the design of algorithms incorporating machine-learned predictions of uncertain quality, methods using machine-learned models within algorithms, using machine-learning to model practical problems and using optimization techniques to analyze and improve machine learning algorithms. The programme consists of a bootcamp, a PhD School, two satellite workshops on different aspects of the topic and a seminar++ series. The organizational team comprises diverse international experts in optimization and machine learning, featuring both junior and senior researchers.

Introduction

Traditional optimization algorithms are based on abstract models that attempt to capture the essential properties of a practical problem. Such algorithms typically provide strong guarantees by assessing their performance on worst-case instances under this model, but which can be overly pessimistic with respect to their actual performance on practical instances. On the other hand, machine learning methods are trained and analyzed on practical data but generally offer no guarantee and poor explainability.

The scientific challenge addressed in this Research Semester Programme “Learning-Enhanced Optimization” is to combine optimization and machine learning to develop data-centric methods attaining both performance guarantees and explainability. This includes the design of algorithms incorporating machine-learned predictions of uncertain quality, methods using machine-learned models within an optimization algorithm, using machine-learning to model practical problems and using optimization techniques to analyze and improve algorithms used in machine learning.
