A machine learning solution to a marketing problem
the recommender system
This essay presents a marketing problematic along with a way of solving it with the help of statistical tools. Precisely, a Recommender System is built to address a marketing problem for a supermarket in Germany. Both the the- oretical and the practical aspects of the use of Machine Learning methods are underlined. Our focus is oriented in two parts. First, we define precisely a problem, from the conceptual meaning to its natural mathematical transla- tion. Second, we provide an analysis that is anchored to business constraints, on top of being an academic paper. Highlight is made on unifying notations for this specific problem, and on comparing different methods before and after their implementation. This work is designed to fulfill the Master’s thesis re- quirements with advanced statistical approach. Mathematical background is emphasized in parallel with hands-on implementation using the open source software R.
