Our 2017 Top Blogs: Data Science

December 15, 2017 at 3:01 PM

Data science continues to be a hot topic in many large firms globally.  2017 saw data science subjects such as R vs. Python, deep learning, natural language, gamification, AI and machine learning being arguably the most topical.

We continue to be passionate about this rapidly evolving world and as it’s the end of the year we’ve decided to look back at our top data science blogs of the year.  We are running a series of these retrospective assemblies of blogs having previously looked back at our best Machine Learning blogs and thereafter our Credit Risk blogs.

If you missed them during the year, I hope you enjoy them now.

The Four Types of Data Analytics

Simplistically, analytics can be divided into four key categories. In this blog post, we focus on the four types of data analytics we encounter in data science: Descriptive, Diagnostic, Predictive and Prescriptive.

The Seven Logical Fallacies to Avoid in Data Analytics

“Lies, damned lies and statistics” is the frequently quoted adage attributed to former British Prime Minister Benjamin Disraeli. The manipulation of data to fit a narrative is a very common occurrence from politics, economics to business and beyond.

In this blog post, we'll touch on the more common logical fallacies that can be encountered and should be avoided in data analysis.

What is Mathematical Optimisation and How Does It Benefit Business?

The word optimisation is used quite loosely and can relate to many different areas.  For example, there is search engine optimisation (getting your website pages to the top of online search results), process optimisation (making existing processes more efficient), code optimisation (making your code run more efficiently) and then there is mathematical optimisation.

In this blog post, we'll be focusing on mathematical optimisation: what it is, how it can be applied in making more optimal business decisions at a customer level, and specifically how it's applied in credit risk.

13 South African Data Science & Machine Learning Meetup Groups To Join

Meetup (www.meetup.com) was founded in 2002 and is an online service used to organise groups that host in-person events for people with similar interests. A social networking tool, unlike any other, Meetup, has more than 35 million users in 180 countries. In South Africa, there are many meetups organised for various interests. Of course, our interests span data science, machine learning and AI, so we took the time to put together a (non-comprehensive) list of the groups who organise meetups that we (and hopefully you) find of interest. We hope you make it out to one of these groups meetups soon!
