How to think like a data scientist to become one

We have all read the punchlines – data scientist is the sexiest job, there’s not enough of them and the salaries are very high.

After my previous blog post I have received questions from people asking how to become a data scientist – which courses are the best, what steps to take, what is the fastest way to land a data science job?

I tried to really think it…

wired-Google DeepMind’s Untrendy Play to Make the Blockchain Actually Useful

For Silicon Valley, the headline was sweet nectar: Google DeepMind, the world’s hottest artificial intelligence lab, embraces the blockchain, the endlessly fascinating idea at the heart of the bitcoin digital currency.

But the buzzwords bely the reality. The lab’s re-imagining of the blockchain has very little to do with AI—or the blockchain, for that matter. If you want AI crossed with the blockchain, try wrapping your head around Numerai, the world’s strangest hedge fund. To…

Being an Ontologist

I am sometimes asked whether I am working on the stats, whether I am making progress on the stats, and what I do with all of the stats.  People are also prone to hyperbole.  I am told that I sure work on a lot of stats, I am always keeping myself busy doing stats, and I am the person to go to for stats.  I suppose my real job is more mysterious than the one others imagine that I do.  I first want to explain that for everyday people, the term “stats” or “statistics” often means historical…

The Future Is Intelligent Apps

I have seen the future! Of course, I seem to say that every other month (maybe that’s because the future keeps changing?), but this is a good one. The future is a collision between big data (and data science) and application development that will yield a world of “intelligent apps.” These “intelligent apps” combine customer, product and operational insights (uncovered with predictive and prescriptive analytics) with modern application development tools and user-centric design to create a…

Data Virtualization: A Supermarket for Data

What is data virtualization? Here’s an analogy using a concept that we can all relate to: a supermarket.

Picture the scene: Shopping list in one hand, shopping basket in the other, you’re ready to tackle your weekly shopping in your local supermarket. Your items range from fruit and vegetables to washing detergent, perhaps with some free-range eggs thrown in for good measure. Quite the eclectic mix, but you know that you’ll be able to find all you need under one…

The Danger of Pursuing Customer 360 View

One of the best parts of my job is talking to a wide variety of customers across a wide variety of industries at a wide variety of different points on their big data journey. I’ve recently had several customer engagements where the client’s top business initiative is creating a Customer 360 View. Danger, Will Robinson!! I think the Customer 360 View business initiative is both dangerous and distracting; it is dangerous because it gives organizations a false goal to pursue, and it…

The IoT-Connected Car of Today— Cases From Hertz, Nokia, NTT, Mojio & Concur Technologies

Imagine a world where your car not only drives itself, but also says intelligent things like these:

  • A hotel is just around the corner and you have been driving for eight hours. Would you like to reserve a room and take rest for a couple of hours?
  • You last serviced the brakes twelve months ago and you have driven your car about 20.000 miles in this duration. Would you like me to find a dealer and book an appointment?
