«Fraud Analytics: Embracing Uncertainty»
Abstract: Fraud has been around since the early days of commerce, continuously evolving and adapting to changing times. The fraud instances can be seen in a wide range of domains such as healthcare and non-life insurance. For instance, in healthcare, overpayments are estimated to correspond up to 10 percent of overall spending. In order to address the complexity and big data size in healthcare, analytical methods are widely utilized. These include but are not limited to methods used for data description, discovery of hidden patterns, classification, and prediction of fraudulent transactions. This talk will cover major data challenges and provide an overview of methods with a brief illustration on emerging probabilistic clustering methods. The talk concludes with a discussion of implementation challenges, future opportunities and perspectives on fraud analytics.
