Abstract Modeling feature interactions in tabular data remains a key challenge in predictive modeling, for example, as used for insurance pricing. This paper proposes the tree-like pairwise interaction network (PIN), a novel neural network architecture that explicitly captures pairwise feature interactions through a sh...
