Scalable Inference of Customer Similarities from Interactions Data using Dirichlet Processes

Braun, Michael; Bonfrer, Andre


Under the sociological theory of homophily, people who are similar to one another are more likely to interact with one another. Marketers often have access to data on interactions among customers from which, with homophily as a guiding principle, inferences could be made about the underlying similarities.
