SCTR7: Data Science and Analytics

Excuse me, do you speak fraud? Network graph analysis for fraud detection and mitigation by Scott Mongeau Executive summary Network analysis offers a new set of techniques to tackle the persistent and growing problem of complex fraud. Network analysis supplements traditional techniques by providing a mechanism to bridge investigative and analytics methods. Beyond base visualization, […]

Network analysis is a rapidly growing analytics domain propelled by the explosion of interest in social networking. The methods rest upon much older foundations in the realms of statistics and social science. Euler’s graph theory was proposed in the early 18th century and Moreno established the foundations for social network analysis (SNA) in the 1930’s. Want […]

As an analytics professional, it may perhaps be no surprise that I believe in a world which is susceptible to analysis – a world which yields to scientific inquiry. Further, I believe that if we invest effort, if we exert what Kahneman would call our System 2, we can improve decisions and overcome our tendency […]

The application of network analysis to the growing challenge of fraud and financial crime is a fast emerging advanced data analytics frontier. As any good fraud investigation knows, fraud and financial crime are as much deep social phenomenon as aspects of financial transactions gone awry. Thus the application of social network analysis is able to […]

A link to a good article proposing that our minds evolved to see patterns and significance, predisposing us to magical and superstitious beliefs: http://theconversation.com/caveman-instincts-may-explain-our-belief-in-gods-and-ghosts-26945 This supports the notion that a major challenge in data science is overcoming our inbuilt behavioral predispositions, for instance the tendency to overfit data samples or to conflate correlation with causation.

MODEL RISK: A central implication of the application of advanced analytics in the finance industry is that models, and model-based decision making, is becoming increasingly complex. There are growing risks for financial institutions that have failed to define and adopt formal approaches to model validation. The Deloitte ‘Global Model Practice Survey’ provides insights into financial […]

A TedX talk I gave November 18th 2013 in Rotterdam, Netherlands at the Rotterdam School of Management (RSM). This talk distills many of the thoughts discussed in this blog. If you like it, please forward! http://www.youtube.com/watch?v=q4d1DArZKgo

Increasingly sophisticated analytics tools and methods are available to derive business insight from data.  However, as a discipline which drives insight from data, the crucial ‘last step’ in the analytics process is about organizational decision making.  A sophisticated, intensive analysis may all be for naught if the crucial last step, framing and committing to a decision, misses the […]

As a companion to my recent post “Correlation versus Causation: The Science, Art, and Magic of Experimental Design”, I wanted to offer a more technical exposition concerning data science approaches to focused causal model development. A fundamental question faced by business analytics professionals and data scientists is whether they have a working correlative and causal […]
