Fraud Detection Using Descriptive, Predictive, and Social Network Analytics (E-learning)

📅 Self-Paced E-learning course
🌍 English


Business Knowledge Series course

Presented by Bart Baesens, Ph.D. Professor at the School of Management of the University of Southampton (UK); or Christophe Mues, Ph.D., Professor at the School of Management of the University of Southampton (UK); or Cristian Bravo, Ph.D, Assistant Professor, Business Analytics, University of Southampton (UK); or Wouter Verbeke, Ph.D., Assistant Professor, Business Informatics, University of Brussels (Belgium); or Stefan Lessmann, Ph.D., Professor, School of Business and Economics, Humboldt University (Germany)

This E-learning course will show how learning fraud patterns from historical data can be used to fight fraud. To be discussed is the use of descriptive analytics (using an unlabeled data set), predictive analytics (using a labeled data set) and social network learning (using a networked data set). The techniques can be applied across a wide variety of fraud applications, such as insurance fraud, credit card fraud, anti-money laundering, healthcare fraud, telecommunications fraud, click fraud, tax evasion, counterfeit, etc. The course will provide a mix of both theoretical and technical insights, as well as practical implementation details. The instructor will also extensively report on his recent research insights about the topic. Various real-life case studies and examples will be used for further clarification.  The E-learning course consists of more than 20 hours of movies, each approximately 5 minutes on average.  Quizzes are included to facilitate the understanding of the material. Upon registration, you will get an access code which gives you unlimited access to all course material (movies, quizzes, scripts, ...) during 6 months year. The E-learning course focusses on the concepts and modeling methodologies and not on the SAS software!  To access the course material, you only need a laptop, iPad, iPhone with a web browser. No SAS software is needed.

Learn how to

  • preprocess data for fraud detection (sampling, missing values, outliers, categorization, and so on)
  • build fraud detection models using supervised analytics (logistic regression, decision trees, neural networks, ensemble models, and so on)
  • build fraud detection models using unsupervised analytics (hierarchical clustering, non-hierarchical clustering, k-means, self organizing maps, and so on)
  • build fraud detection models using social network analytics (homophily, featurization, egonets, PageRank, bigraphs, and so on).
