Graph distances for determining entities relationships: a topological approach to fraud detection

J. M. Calabuig, H. Falciani, A. Ferrer-Sapena +2

Given a set $\Omega$ and a proximity function $\varphi :\Omega \times \Omega \to {\mathbb{R}}^{+}$, we define a new metric for $\Omega$ by considering a path distance in $\Omega$, that is considered as a complete graph…
