Making Sense of Bank Networks Using High-dimensional Classification Techniques


We build an integer-programming optimization model to classify the entities of a directed network in a high-dimensional feature space. The network is associated with cross-border payments flowing through the global SWIFT platform. Our objective is to detect, in the network of an international commercial bank, the low-profit high-risk entities, so they can be removed without losing a lot of business.
