Descrição

Detect fraud earlier to mitigate loss and prevent cascading damage 'Fraud Analytics Using Descriptive, Predictive, and Social Network Techniques 'is an authoritative guidebook for setting up a comprehensive fraud detection analytics solution. Early detection is a key factor in mitigating fraud damage, but it involves more specialized techniques than detecting fraud at the more advanced stages. This invaluable guide details both the theory and technical aspects of these techniques, and provides expert insight into streamlining implementation. Coverage includes data gathering, preprocessing, model building, and post-implementation, with comprehensive guidance on various learning techniques and the data types utilized by each. These techniques are effective for fraud detection across industry boundaries, including applications in insurance fraud, credit card fraud, anti-money laundering, healthcare fraud, telecommunications fraud, click fraud, tax evasion, and more, giving you a highly practical framework for fraud prevention. It is estimated that a typical organization loses about 5% of its revenue to fraud every year. More effective fraud detection is possible, and this book describes the various analytical techniques your organization must implement to put a stop to the revenue leak. Examine fraud patterns in historical data Utilize labeled, unlabeled, and networked data Detect fraud before the damage cascades Reduce losses, increase recovery, and tighten security The longer fraud is allowed to go on, the more harm it causes. It expands exponentially, sending ripples of damage throughout the organization, and becomes more and more complex to track, stop, and reverse. Fraud prevention relies on early and effective fraud detection, enabled by the techniques discussed here. 'Fraud Analytics Using Descriptive, Predictive, and Social Network Techniques' helps you stop fraud in its tracks, and eliminate the opportunities for future occurrence. The sooner fraud detection occurs the better--as the likelihood of further losses is lower, potential recoveries are higher, and security issues can be addressed more rapidly. Catching fraud in an early stage, though, is more difficult than detecting it later, and requires specific techniques. Packed with numerous real-world examples, 'Fraud Analytics Using Descriptive, Predictive, and Social Network Techniques' authoritatively shows you how to put historical data to work against fraud. Authors Bart Baesens, Veronique Van Vlasselaer, and Wouter Verbeke expertly discuss the use of unsupervised learning, supervised learning, and social network learning using techniques across a wide variety of fraud applications, such as insurance fraud, credit card fraud, anti-money laundering, healthcare fraud, telecommunications fraud, click fraud, and tax evasion. This book provides the essential guidance you need to examine fraud patterns from historical data in order to detect fraud early in the process. Providing a clear look at the pivotal role analytics plays in managing fraud, this book includes straightforward guidance on: Fraud detection, prevention, and analytics Data collection, sampling, and preprocessing Descriptive analytics for fraud detection Predictive analytics for fraud detection Social network analytics for fraud detection Post processing of fraud analytics Fraud analytics from an economic perspective Read 'Fraud Analytics Using Descriptive, Predictive, and Social Network Techniques' for a comprehensive overview of fraud detection analytical techniques and implementation guidance for an effective fraud prevention solution that works for your organization.

'Fraud Analytics Using Descriptive, Predictive, and Social Network Techniques' offers a current, state-of-the-art detection and prevention methodology, describing the data necessary to detect fraud. Taking you from the basics of fraud detection data analytics, through advanced pattern recognition methodology, to cutting-edge social network analysis and fraud ring detection, this book presents essential coverage of: The fraud analytics process model Big data Break point/peer group analysis Anomaly detection Linear/logistic regression Neural networks Ensemble methods Social network metrics Bipartite graphs Community mining Visual analytics Model monitoring and backtesting Insightful and clearly written, this hands-on guide reveals what you need to know about fraud analytics and the secret to putting historical data to work in the fight against fraud.
