Brief biography

I revieved a PhD from Iowa State University in Applied Mathematics in 2012. Prior to that I revieved a bachelors degree from Minnesota State University - Mankato in Mathematics and Computer Science.

I am currently an Associate Professor of Mathematics at the UWL where my interests include:

  • teaching undergraduate mathematics with special emphasis on applications,
  • co-organizing a student research group on Machine Learning and Data Science, 
  • researching cutting machine learning techniques and applying ideas to business and marketing,
  • and collaborating with local companies on research and student opportunities.

published

Marco Vriens, Marketing and Chad Vidden, Mathematics & Statistics, co-authored the article "The benefits of the Shapley Value for key drivers analysis" in Applied Marketing Analytics and was accepted for publication by Henry Stewart. Linear (and other types of) regression are often used in what is referred to as ‘driver modelling’ in customer satisfaction studies. The goal of such research is often to determine the relative importance of various sub-components of the product or service in terms of predicting and explaining overall satisfaction. Driver modelling can also be used to determine the drivers of value, likelihood to recommend, etc. A common problem is that the independent variables are correlated, making it difficult to get a good estimate of the importance of the ‘drivers’. This problem is well known under conditions of severe multicollinearity, and alternatives like the Shapley-value approach have been proposed to mitigate this issue. This paper shows that Shapley-value may even have benefits in conditions of mild collinearity. The study compares linear regression, random forests and gradient boosting with the Shapley-value approach to regression and shows that the results are more consistent with bivariate correlations. However, Shapley-value regression does result in a small decrease in k-fold validation results.
