Popular Software Skills in Data Science Job postings.

This exercise was done to understand the software skills that are in high demand for Data Science. Analysis was done by extracting the job postings from popular online websites. The findings are interesting. R continues to be the most popular skill, found in 70% of the postings. Python follows as a close second. Surprisingly, in spite all the talk about "Big Data Science", SQL comes up third. This shows that traditional RDBMS still continue to be the base for machine learning work…

Data Science Musings: We Make Better Health Choices When We Think We're in Control

Obviously, there are few topics that are as morbid as our own morbidity, and it is for this reason that we often avoid thinking about it. However, as it turns out, how we view the probability of the causes and the timing of our own demise is very important. Why? It is because these views are subconsciously affecting how we approach health related decisions that we are making every day.

Think of it this way. If you believed that you would likely die from an…

Data Science for Improved Democracy

The current (November 2014) United States election reminds us that sophisticated data science techniques are employed on the public in attempt to influence opinion and persuade votes. The slick television advertising, debate prevarications, and policy position distortions and exaggerations have soured many citizens on the current state of modern democracy. Indeed, most feel we are not getting the straight scoop - the…

Why Paddy Cosgrave hired Data Scientists to grow websummit from 400 to 20k attendees in just 4 years

Arguably no technology conference in history has grown faster. Somehow we’ve achieved that growth with no background in the conference industry and no resources to speak of, and all from a pretty peripheral location called Dublin. - Paddy Cosgrave

Huge Trello List of Great Data Science Resources

I have been reading and collecting data science resources for years (back in the days when BI / BA was all the rage). While there are lots of resources on the net, not all are great and some are even misleading.

Now, I have updated my collection and placed them into a neat Trello list, open to all.

Of course it features some of the great and interesting articles from data science central:…

22 Non Statistical Questions for a Statistician

We have always believed that when the world of business collides with the world of math, magic unfolds. As these 2 worlds collide, it also presents a set of unique challenges - bridging the semantic language gap between business and math. Modelling complex business outcomes using math requires an interdisciplinary team consisting of business folks, data folks and math folks. While doing so business folks are always at a loss because a language chasm exists. Math folks love their ”geek…

Data Shinobi: 2 - The Tree of the Data Shinobi

Having looked at the fundamentals in the first blog, the natural next step is to understand the various types of strategies to "attack" the data and make it reveal useful information. However, there is one step we must take just before that: Understand the "enemy" i.e. the problem at hand and the data available.

The Tree of the Data Shinobi:

Data Shinobi: 1 - The Fundamentals

With loads of content and hype about Data Science, Analytics and Big Data coming up every day, I felt compelled to share my journey and experiences in exploring this space.

While there are a whole bunch of directions these subjects could be approached from, I present here the path that I found most convenient to tread. I would like to call it the path…
