Intel® Summary Statistics Library: how to detect outliers in datasets?

Earlier I computed various statistical estimates like mean or variance-covariance matrix using Intel® Summary Statistics Library. In those cases I knew for sure that my datasets did not contain “bad” observations (points which do not belong to the distribution which I observed) or outliers. However, in some cases we need to deal with datasets which are contaminated with outliers.

Mainframe SOA

In many conversations I participate in regarding Service Oriented Architecture (SOA), part of the conversation oftens leads to "....how best can I incorporate my mainframe in the SOA architecture...".  There are a number of mainframe SOA-enabling options, and in this post I will share my opinion on the application of a short-list of tried and true approaches.

Intel® Ordinary Differential Equations Solver Library - released on Whatif.intel.com

The Intel® Ordinary Differential Equation Solver Library (Intel® ODE Solver Library) is a powerful, cross-platform tool set for solving initial value problems for Ordinary Differential Equations. It offers explicit, implicit, and mixed solvers for non-stiff, stiff, and ODE problems with variable stiffness. The solvers have a set of configurable parameters that allow experienced users to tune the algorithms for both better accuracy and performance.

  • Integrating SaaS to the Enterprise with SOA

    Integrating the hot, new SaaS application into a company can often be a challenging undertaking.  The SaaS application was acquired for a pressing departmental need, yet manually re-inputting and syncing key data like employee, vendor or supplier master directories is not practical.  Manually coordinating a sale by the customer saying "yes" with a win recorded in the sales force automation tool yet hand crafting delivery instructions in the order module of the ERP is not really a sustainable business proc

    SOA and SaaS ... What's the Difference?

    This might sound odd to some of you reading this, but I am regularly asked the following question ... "What is the difference between SOA and SaaS?".

    Given the acronym soup of the IT industry I am not surprised to get that question and expect to for some time to come. The simple answer is that:

    Usage of a SOA "soft appliance" for Federated SOA

    In my last several posts I have been sharing the concepts of a new product category I have been referring to as a SOA "soft appliance".  Those posts have covered the origin of the idea, features, benefits and how is it similar to and different from other types of service-enabling infrastructure.

    Going forward for a while, I plan on posting on the deployment architectures and usages of a SOA "soft appliance" platform like Intel SOA Expressway.

    The differences between a hard and soft SOA appliance

    In the last blog I wrote about the similarities and differences between a SOA "soft appliance" like Intel SOA Expressway and an ESB-based product.  Two key questions often arise out of that discussion: (1) Why do I need a SOA appliance if I already have an ESB, and (2) Why is a "soft appliance" better than an easy-to-deploy, secure and high-performance hardware appliance?
