Description

“AFRAID: Active Fraud Investigation and Detection using Advanced Network Analysis”: Fraud is often socially contagious, resulting in an urge in both academia and industry to exploit (social) networks and to identify so-called guilt-by-associations. One of the main techniques in advanced network analysis is to deploy influence propagation algorithms. Such algorithms derive an exposure score for every network member which quantifies the probability to fraud. Exposure scores typically depend on the fraudulence, intensity and recency of the relationships with one’s peers in the network. In this presentation, Véronique will discuss how the performance of influence propagation algorithms can be largely improved by small investments in human interaction, a field commonly known as active learning. In active fraud investigation and detection, algorithms are optimized by asking a limited set of automatically selected questions to business experts. Results show that only limited human interaction has a huge impact on the performance of detection models. Véronique graduated in 2015 as Doctor in Business Economics at the KU Leuven with the department of Information Management and Decision Sciences under prof. dr. Bart Baesens. Her Ph.D is oriented towards the development of fraud detection frameworks and solutions from a data science perspective. She is co-author of the book “Fraud Analytics Using Descriptive, Predictive, and Social Network Techniques: A Guide to Data Science for Fraud Detection”. Since November 2015, Véronique has started as an Analytical Consultant at SAS with a strong interest in Data Analysis, Data Mining and Social Network Analysis. THE DATA INNOVATION EVENT ABOUT DIGITAL TRANSFORMATION #DIS2016 will focus this year on Digital Transformation and all about managing and monetizing disruptive innovations. Whether created through opportunity capture, adaptive defense or new ventures, today's digital ecosystems are evolving rapidly. As rapidly as companies compete for top talent, drive higher engagement levels from their customers, and ultimately define their organization's future profitability. The digital ecosystem needs to be designed, planned and implemented now, as organizations are called upon to integrate the latest virtual technologies, pioneer new business models and guide their organizations toward next generation environments. If smart, robust digital innovation and technology strategies are your priority, you won't want to miss #DIS2016 as we uncover the keys to success.
