Shea plays the role of host today and talks shop with Anders and Nick Vander Heyden, who competed as part of a team in the 2021 Milliman Health Practice Hackathon. The gang covers a wide range of topics, including team strategy and organization, exploratory data analysis, feature engineering, and choice of algorithm. Although Anders and Nick were generally pleased with their team’s performance, they discuss what they wish they had done differently and what they would have done to refine their predictions with more time. The discussion illuminates the practical considerations involved in tackling a real-world predictive analytics project and why the human element is still a critical part of machine learning.
