When you see google ads on Google search result pages or elsewhere, the ads that are displayed in front of you eyes (should) have been highly selected in order to maximize the chance that you convert and generate ad revenue for Google. Same on Facebook, Yahoo, Bing, LinkedIn and on all ad networks.

If you think that you see irrelevant ads, either they are priced very cheaply, or Google's ad relevancy algorithm is not working well.

Ad scoring algorithms used to be very simple,…

Here is how it works : Suppose that you are working for a Telco and wish to implement a new Churn prediction model. Rather than running this project in-house, you submit your data to Kaggle. What happens next is that -hopefully- many…

Of all the ills that impede development around the world, persistent conflict may be the most pernicious and the most widespread. As the World Bank noted in its April 2011 report, insecurity “has become a primary development challenge of our time. One-and-a-half billion people live in areas affected by fragility, conflict, or large-scale, organized criminal violence, and no low-income fragile or conflict-affected country has yet achieved a single United Nations Millennium Development…

What's your cloud integration strategy? If you're like most IBM i shops, much of your data interchange is handled via good old EDI or flat file transfers. But the rapid spread of cloud services is hastening the move to more sophisticated forms of data and application integration and interchange. According to EXTOL which develops integration broker software for IBM i and other platforms, the day is fast approaching when companies will need new techniques for integrating cloud…

The Washington Education Association (WEA, in Washington State) is partnering with Aon Hewitts (Illinois), a verification company, to eliminate a specific type of health insurance fraud: teachers reporting non-qualifying people as dependents, such as an unemployed friend with no health insurance. The fraud is used by "nice" people (teachers) to provide health insurance to people who would otherwise have none, by reporting them as spouse or kids.

Interestingly, I saw the letter sent to…

Big Data, housed in new and disruptive technologies, is expected to account for more than 50 percent of the world’s data in the next five years, according to a a new study. While it offers huge and untapped value, the inevitable result is stress and strain on the world’s Interent infrastructure as companies seek to manage this explosion of information.

The new study, released jointly by Internet Research Group and Infineta Systems a provider of WAN optimization systems, examines how…

This year has seen consolidation and engineering around improving the basic storage and data processing engines of NoSQL and Hadoop. That will doubtless continue, as we see the unruly menagerie of the Hadoop universe increasingly packaged into distributions, appliances and on-demand cloud services. Hopefully it won’t be long before that’s dull, yet necessary, infrastructure.

Looking up the stack, there’s already a line up of cool tools for data scientists and not to be left out,…

Back in 2000 I was working with GE's analytic team to improve sales forecasts for NBC Internet, a web portal owned by NBC. The sales / finance people were using a very basic formula to predict next month sales, based mostly on sales from previous month. With GE, we started to develop more…

The smart grid is leading the power industry into a data and analytics boom as its implementation phase gives way to its value phase, according to Christine Richards, senior analyst with Energy Central's Utility Analytics Institute.

Richards defined the decade from 2000 to 2010 as the smart grid's development phase, the five-year period from 2007 to 2012 as the infrastructure, or implementation phase and the decade from 2010 to 2020 as the value phase.

In the value phase, grid…

According to the Gartner report, "Demand trends have given rise to new challenges in 2011. Fresh needs arising from contemporary challenges are presenting new opportunities in this market as buyers seek to address data integration as a critical aspect of a coherent information management capability, and to integrate disparate data sources (including emerging sources such as 'big data') and new data types into a cohesive and usable set of information."(1) SAP is helping its customers address…

First, let me say how pleased I am to be a part of the Data Science Central community. While I was the VP of Marketing at EMC Greenplum, I had a front row seat to the dynamic and very exciting “Big Data” and “Data Science” shows. EMC Greenplum has played a pivotal role in helping organizations of all sizes start the process of orienting their businesses and decision-making around data. It has been said, and I’ll say it again –the companies that embrace the power of data and live that life…
