The new superstars: data scientists | Silicon Angle


Data Scientists are the new rock stars of the technology world.

Don’t believe me? At last week’s Strata conference, throngs of attendees were jockeying so intensely for position to listen to bitly Data Scientist Hilary Mason that I thought I might be at a Bon Jovi concert circa 1986.

Ok, perhaps I’m exaggerating just a…

IBM launches city parking analytics system | IDG News

IBM has launched a system designed to help cities ease parking congestion and collect more parking fees, the company announced Wednesday. The service could also help motorists find parking spaces more easily in crowded urban areas.

"The existing parking systems are pretty inefficient [in terms] of how cities manage them," said Vinodh Swaminathan, IBM's director of intelligent transportation systems. "Think of a parking spot as a revenue-producing asset. With the…

Identifying the number of clusters: finally a solution

Here I propose a solution that can be automated and does not require visual inspection by a human being. The solution can thus be applied to billions of clustering problems, automated and processed in batch mode.

Note that the concept of cluster is a fuzzy one. How do you define a cluster? How many clusters in the chart…

NASA satellite fall on Earth: 1-in-3200 chance to hit someone. How so?

How was this statistic computed? Is it based on the formula

Q = 1 - (1 - x/y)^26 = 1/3200,


  • If we pack all 6 billion human beings into a very compact square area, that area will cover x square miles.
  • The total area of the earth is y square miles,
  • Q is the chance that at least one out of 26 pieces (expected to fall on earth) hits the square area in question

If this is the case, then the human beings occupy a proportion R = 1 - {1…

Lifetime value of an e-mail blast: much longer than you think

See below an example of an Analyticbridge email campaign that was monitored over a period of about 600 days. It clearly shows that 20% of all clicks originate after day #5. Yet most advertisers and publishers ignore clicks occurring after day #3. Not only 20% of all clicks occurred after day #3, but the best clicks (in terms of conversions) occurred several weeks after the email…

Scientists tried on manslaughter charges for providing incorrect predictions | USA Today

ROME (AP) – Seven scientists and other experts have gone on trial on manslaughter charges for allegedly failing to sufficiently warn residents before a devastating 2009 earthquake that killed more than 300 people in central Italy.

The case is being closely watched by seismologists around the globe who insist it's impossible to predict earthquakes and dangerous to suggest otherwise, since seismologists will be discouraged from issuing any advice at all if they fear…

Newton's Laws of Motion and its relevance to Business Intelligence (BI)


Hi there! If you are perplexed by the title of this blog article, I wouldn't be surprised. I am sure you would be muttering under your breath "What on earth have Newton’s Laws of Motion got to do with Business Intelligence (BI)?"

Before I quench your curiosity to know more, let me for the benefit of everyone state here the three Laws of Motion as discovered by Sir Isaac Newton.

Law I: (1)

Creativity vs. Analytics: Are These Two Skills Incompatible?

In a nutshell, are great analytic people lacking creative skills? And are great creators lacking analytic skills? How to fix this gap?

Here are a few interesting questions:

  • Should analytic people focus on measuring, and nothing else? 
  • Do analytic people lack business skills because they were odd kids in high school, because the way the school system is working in US?
  • Is it impossible to hire great analytic people combining both soft and hard skills, because…

Barriers to hiring analytic people

You hear all the time that it is very hard to find and hire a great data scientist. Yet these scientists can't find a job, and are typically unemployed for many months after graduating or after being laid off - even those with 15 years of experience and stellar degree and accomplishments. 

So what's the problem? I'm suggesting a few possibilities:

  • Candidates lack business acumen
  • Candidates have poor communication skills, are asking too much…
