Machine Learning for Optimization: Creating Personalized Concert Festival Schedules

Professor J. Christopher Beck, Department of Mechanical & Industrial Engineering, University of Toronto

Abstract

The power of off-the-shelf machine learning tools combined with the availability of data is changing how organizations and individuals make decisions. As an illustration, we address the creation of a personalized schedule for a large-scale music festival. Popular music festivals can exceed 600 shows per day across dozens of venues. With many artists performing at overlapping times in distant locations, preparing a personal schedule is a challenging task. Equally problematic is understanding a user’s preferences over the artists and shows without an unrealistic amount of data entry by the user. Using a small set of stated user preferences and available online tags, in real-time, we learn a user’s preferences over all artists. These preferences are then used to formulate a combinatorial optimization problem to provide optimal personal schedule. We evaluate our web-based system on a large set of real festival timetables, demonstrating that we can learn preferences and provide optimal solutions in about 10 seconds on average, making our system suitable for online use. This is joint work with Eldan Cohen at the University of Toronto.
