Data science job ads that do not attract candidates, versus those that do

There's no shortage of great talent for companies such as Apple, Google, Intel, Facebook, Wikipedia and some exciting startups. But what if you are not one of these?

I received the following job ad in my mailbox (see below in italics), from a third-party recruiter, and it's probably for a data science position at Nike near Portland, Oregon (my guess). Basically, it's a 6-month gig to build an A/B platform.…

How invisible data could provide the tobacco industry a second life

This indeed applies to all industries and all products. In short, how do you detect new uses of a declining product (cigars in this case) that could turn them into a good product and revive the industry in question? The tobacco industry has tried to sell outside US (especially Asia) to make up for declining sales in US. They came with e-cigarettes. But they never thought of a tobacco use in a context not associated with addiction.…

Building a house and building a data-analytic model

If I want to build a house, wouldn't it be wise to learn carpentry? Does the analogy hold for data-analytic multivariate models? Or is it simply enough to let a machine do it, with no knowledge by the machine operator of how to interpret the results from those modeling efforts? Or is it true, as one person has recently asserted, that he could replicate ALL statistical procedures and techniques using MapReduce, without knowing anything about statistics and probability, or the vast collection…

The Dangers of the "Talent Shortage" Myth

Every time a new technology disrupts the job market a "skills shortage" is debated between economists and politicians. The story isn't new - 10 years ago recruiters were asking for programmers with 10+ years experience in Java. The gap is widened by non-technical recruiters employing rigid traditional hiring practices. The truth is that there are all kinds of smart people with relevant skills that don't fit into HR's pigeonhole - we're generalists, not specialists. The onus…

The Algorithmic Man - Epic Battle Against Headless Apparitions

There was a television interview of a man who had to deal with severe breathing problems through much of his adult life.  He underwent various procedures although he found little relief.  In fact, the adverse impact to his body was long-lasting.  So he was surprised to discover how he was extremely allergic to his breakfast cereal, something that he ate almost without fail.  When he stopped eating the cereal, his breathing problems disappeared.  I am sure that many people would regard the…

Take Me Out to the Data

America’s pastime is ripe with opportunities to dust off your data visualization tools and practice your Big Data swing.

As spring begins and bees collect pollen for honey, baseball statisticians collect millions of interesting facts about this year’s baseball season. Ever since the 1870s when sportswriter Henry Chadwick began pulling together players’ data, people have been keeping score on everything from hits and runs to strikeouts and averages.

This year is…

Data Embodiment – an Ecosystemic Approach

Embodiment is comparable to the idea of an “ecosystemic” or “holistic” approach. In an ecosystem, each thing affects everything else. In light of the interrelationship, a person would not attempt to correct a problem by considering only a single piece of the puzzle. Instead, there is a need to bring together many aspects of the body. To understand embodiment, it is necessary to recognize how “the body” separates an organism from its environment; in a manner of speaking, the body represents…
