How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more

Article
We describe a methodology for identifying and ranking candidate audit targets from a database of prescription drug claims. The relevant audit targets may include various entities such as prescribers, patients and pharmacies, who exhibit certain statistical behavior indicative of potential fraud and abuse over the prescription claims during a specif...

At WinterSim 2011, we originally proposed an agent-based framework for healthcare simulations, enabling flexible integration of multiple simulation models, including models of disease progression, effects of provider interventions, and provider behavior models that are responsive to contractual incentives. In this paper, we report results using our...
Article
Sound marketing decisions often require understanding the cause-and-effect relationships between treatment and outcomes. Market research traditionally approaches such questions by designing randomized experiments that aim to isolate the effects of the specific treatment from other effects. We review an alternate methodology that is well suited to o...
Article
The typical marketing environment in the business-to-business (B-to-B) world is very complex. Companies selling in that environment initiate promotional contacts across different channels and in support of various product lines targeted at many marketable points-of-contact. A fundamental question is “Given a budget of marketing contacts, how can th...
Article
Chid Apte, manager of data analytics, and his team conduct pure and applied research in data mining and related topics and discusses about the success of data mining. The greatest success of data mining is that it has opened the possibility that businesses that have large amounts of data can perform analysis and explorations of that data in a littl...
Article
Data mining mitigate many of the factors by considering virtually unrestricted amounts of data and analyzing very complex data relationships to make better decisions. Most organizations try to analyze the problems using either existing knowledge or traditional analysis tools, such as query and reporting, spreadsheets, and online analytic processing...
Article
IBM's emergency response service provides real-time intrusion detection (RTID) services through the Internet for a variety of clients. As the number of clients increases, the volume of alerts generated by the RTID sensors becomes intractable. This problem is aggravated by the fact that some sensors may generate hundreds or even thousands of innocen...

The list of enterprises that have taken the leap across the data mining technological chasm continues to grow. Some have fallen into the abyss while others have landed safely on the other side. Our experience has shown that there are common Critical Success Factors that distinguish the fortunate ones from their unlucky counterparts. We would like t...

Article
An analysis of the low-order model for two-dimensional fluid flow with shear proposed by Drake [ital et] [ital al]. [Phys. Fluids B 4, 488 (1992)] is undertaken. Their two-term model for the shear is an extension of the model put forth by Howard and Krisnamurti [J. Fluid Mech. 170, 385 (1986)], and is shown to be an improved model in the sense that...
Article
The nonlinear behavior of the two-dimensional Benard problem with periodic boundary conditions in the horizontal direction is studied with particular emphasis on the role of self-consistent chaotic advection. The results show a complex interplay between vortices driven by the Benard (Rayleigh--Taylor) instability and shear flow, which is driven by...
