The role of predictive analytics in business


Data is everywhere. We generate data when using an ATM, browsing the Internet, calling our friends, buying shoes in our favourite e-shop or posting on Facebook. Companies collect this data en masse in order to make more informed business decisions, such as:

Data Transmutation vs. Data Analytics: Round 1


I became a Data Science practitioner in probably the most peculiar, counter-intuitive way of becoming one.

18 Reasons Data Scientists are Difficult to Manage

Of course each data scientist is different, so please take this criticism with a grain of salt. By a long stretch, they don't apply to all data scientists.


  1. Data scientists are creative and bring disruptive IP (intellectual property), and this can cause havoc for their company. 
  2. They can steal and…

How to Become a Data Scientist on a Shoestring

In the increasing number of organizations where data science is valued, data scientists know they are working on the cutting edge solving problems in ways no one has thought of before. They generally command very decent salaries, too.…

Top 10 Commercial Hadoop Platforms

Hadoop – the software framework which provides the necessary tools to carry out Big Data analysis – is widely used in industry and commerce for many Big Data related tasks.

It is open source, essentially meaning that it is free for anyone to use for any purpose, and can be modified for any use. While designed to be user-friendly, in its “raw” state it still needs considerable specialist knowledge to set up and run.

Because of this a large number of commercial versions have come…

The Biggest Risks of Big Data

As with any business initiative, a Big Data project involves an element of risk. Any project can fail for any number of reasons - bad management, under-budgeting or a lack of relevant skills. However Big Data projects, due to their nature, bring their own specific risks.

Due to the advanced technology often needed, and the relative newness of the skillsets required to truly “think Big” (or as I prefer to say, “…

Get Past the Flash and Into the Data

Guest blog from David Lefkowich at FreeSight


Today’s world is split-second. Whether you’re pitching an idea, selling a product, or presenting last quarter’s results, if you don’t grab your audience’s attention in the first moment, you are beat.

In Defence of Small Data

There has been enough buzz about Big Data over the past year or two to create a very big data file.  It seems that if you do not have a strategy around big data, mining ecommerce and social media sites for new insights into your customers, using new data management software tools like Hadoop, you are at a serious disadvantage to your competitors who are all jumping on the big data bandwagon.


And - there is merit to this line of thought for some companies.  The increase in the…

The Decision Frame

There are a number of movies that I consider much more suitable for television than theatre: Alien Versus Predator; Doom; Snakes on a Plane; The Cave; The Colony. The stories of these movies play out in environmentally-limited sometimes enclosed settings. In the theatre, I considered Alien Versus Predator the worst movie I ever had to sit through in my entire life, second perhaps only to the original Tron. But at home on a 36-inch display, it has become one of my all-time favourites. On the…

An introduction to ElasticSearch

Search engines are now an integral part of people’s everyday lives. We are used to having access to information at the click of a button. However we rarely think how much work goes into this ability to search for information.
