Why You Should Encourage Your Daughters to Become Data Scientists

The fact that women are underrepresented in technology roles is not a novel observation. Data science roles follow this unfortunate pattern. In the United States, women hold a mere 26% of data jobs. The data science field is booming and the rise of big data is visible almost everywhere. While data science is still new, as a society, we cannot be complacent with women making up just a quarter of the field — we need more women in data…

How an Artificial Intelligence project is helping to make Brazilian politicians more accountable?

Chamber of Deputies is the lower house of National Congress of Brazil. It has 513 congress people, 219 of them max out their monthly spending that can be reimbursed. One congressperson gets 30 gas tanks filled every month. Two congress people have claimed 13 meals paid on the same day. These were identified by an Artificial Intelligence project - Operation Serenata de Amor. The platform has analysed more than 3 million notes and raised about 8000 cases in irregular public…

This is Why Data Scientists Make So Much

If you have ever wondered or still wonder what the best job in Silicon Valley is, which ranks No. 1 on Glassdoor’s best jobs in America list for 2016 and 2017, you can stop now. Also referred to as the sexiest job of the 21st century, it’s data science.

Whether you look at the salary and packages currently being offered for this job, or the rise in demand for these professionals, the numbers still look pretty impressive. According to Glassdoor, data scientists make on average $128,549…

Passive vs. active data scientists

While the skills required or expected from data scientists can vary based on the organization or domain they work in, being a data scientist can be viewed not merely as owning a set of skills, but also as having a certain mindset. In that sense I can differentiate between passive data scientists and active data scientists.

The passive data scientists will use the data they receive, or perform basic tasks to collect data stored in one or several central sources. Once they have the…

Data Lineage: The History of your Data

Data Denialism

A common scenario that data analysts in general encounter is what I like to describe as "data denialism". Often, and especially while consulting, an analyst will find that the data tells a different story than what the customer holds to be true. It is also often the case that, when presenting this finding, the customer will outright deny the evidence, asserting that either the data or the analysis must be wrong. For example, it may be that a retailer focused on the…

The essence of machine learning is function estimation

Machine learning is cool. There is no denying in that. In this post we will try to make it a little uncool, well it will still be cool but you may start looking at it differently. Machine learning is not a black box. It is intuitive and this post is just to convey that. 



If I give you this function f(x) = x^2 + log(x) and ask you to tell me what will be f(2), you will first laugh at me and then run away to do something important. This is trivial for you,…

Open Source Deep Learning Frameworks and Visual Analytics

Deep Learning gets more and more traction. It basically focuses on one section of Machine Learning: Artificial Neural Networks. This article explains why Deep Learning is a game changer in analytics, when to use it, and how Visual Analytics allows business analysts to leverage the analytic models built by a (citizen) data scientist.

What is Deep Learning and Artificial Neural Networks?

Deep Learning is the modern buzzword for artificial neural networks, one of many concepts…

Data is not facts - the impossibility of being unbiased

Best intentions

We talk a lot about making decisions based on data but we need to be careful about how hard and fast those decisions are. Our decisions are only as good as our data and our analysis.

Neither can be perfect. Data is always a sample of the full scope of reality and analytics is always an interpretation…

It’s been a rather quiet summer on Data Science Central with fewer blog posts being published than at other times of the year, but I guess it shouldn’t be too much of a surprise – DSC has had to compete against summer holidays, the Euro 2016 football tournament and the Rio 2016 Olympics.

Of the relatively few that have been published, there have been a few gems. At the time of writing, the 5 blog posts on this list have been read by almost 60,000 of you.

Why Good Data Scientists are Worth the Big Bucks

Data scientist is the ‘Sexiest Job of the 21st Century’, so say Thomas Davenport and DJ Patil in their seminal 2012 Harvard Business Review article.

Since then, data scientists have been very much in demand and their wages have soared. Compared to statisticians, computer programmers and AI guys (who are still regarded as geeks), they are extremely well paid.

But…

Statistics is Dead – Long Live Data Science…

I keep hearing Data Scientists say that ‘Statistics is Dead’, and they even have big debates about it attended by the good and great of Data Science. Interestingly, there seem to be very few actual statisticians at these debates.

So why do Data Scientists think that stats is dead? Where does the notion that there is no longer any need for statistical analysis come from? And are they right?

Is statistics dead or is it just pining for…

We wanted to gather and analyze news content in order to look for similarities and differences in the way two journalists write headlines for their respective news articles and blog posts. The two reporters we selected operate in, and write about, two very different industries/topics and have two very different writing…
