Transfer Learning for Credit Card Fraud Detection: A Journey from Research to Production
Wissam Siblini, Guillaume Coter, Rémy Fabry +5
The dark face of digital commerce generalization is the increase of fraud attempts. To prevent any type of attacks, state-of-the-art fraud detection systems are now embedding Machi…
A Constrained Randomized Shortest-Paths Framework for Optimal Exploration
Bertrand Lebichot, Guillaume Guex, Ilkka Kivimäki +1
The present work extends the randomized shortest-paths framework (RSP), interpolating between shortest-path and random-walk routing in a network, in three directions. First, it sho…
A Bag-of-Paths Node Criticality Measure
Bertrand Lebichot, Marco Saerens
This work compares several node (and network) criticality measures quantifying to which extend each node is critical with respect to the communication flow between nodes of the net…
An experimental study of graph-based semi-supervised classification with additional node information
Bertrand Lebichot, Marco Saerens
The volume of data generated by internet and social networks is increasing every day, and there is a clear need for efficient ways of extracting useful information from them. As th…
Two betweenness centrality measures based on Randomized Shortest Paths
Ilkka Kivimäki, Bertrand Lebichot, Jari Saramäki +1
This paper introduces two new closely related betweenness centrality measures based on the Randomized Shortest Paths (RSP) framework, which fill a gap between traditional network c…
Semi-Supervised Classification Through the Bag-of-Paths Group Betweenness
Bertrand Lebichot, Ilkka Kivimäki, Kevin Françoisse +1
This paper introduces a novel, well-founded, betweenness measure, called the Bag-of-Paths (BoP) betweenness, as well as its extension, the BoP group betweenness, to tackle semisupe…
