Scientific visualizations in early mathematical biology and morphology.

In 1917, Darcy W. Thompson, a pioneering mathematical biologist wrote a beautiful and exceptional demonstration about the relation between morphology and biology. Indeed, Thompson introduces its famous and elegant form of varying the Cartesian space as a tool to show the analogies between species. The central thesis of…

Lenders, know thy customer

Consumer complaints about financial institutions are never all that surprising. When it comes to money—purchasing, saving and borrowing—many people are sensitive, protective, and cautious, especially in tough economic times. Consumer confidence has waned in the past decade, and the reputations of banks (mortgage lenders, in particular) has suffered. Yet…

Practical illustration of Map-Reduce (Hadoop-style), on real data

Here I will discuss a general framework to process web traffic data. The concept of Map-Reduce will be naturally introduced. Let's say you want to design a system to score Internet clicks, to measure the chance for a click to convert, or the chance to be fraudulent or un-billable. The data comes from a publisher or ad network; it could be Google. Conversion data is limited and poor (some conversions are tracked,…

Not just analyze the log, mine it.

Much more devices held, much more messages sent, much more data up in the air.

Upon the arrival of IOT (Internet of Things) era, number of connected devices grows rapidly, the signals of which stack up mines containing valuable, hidden insights.

We used to analyze log files for risk management, spotting the anomalies and exceptions based on outlined records. Via the ever-richer meta data and context, we are entitled to weave more story from the strings now. By union or…

The Data Science Toolkit - taking your first steps towards becoming a Data Scientist

When I stumbled upon the phrase "Data Scientist" 3 years ago, I immediately recognized it as my best prospect for a productive career. How to start? What are the tools of the trade?

This is the blog post I wish I could have read back then.

Many of the things I list here didn't exist or were unstable until recently.

I discovered the "predictive analytics" rabbit hole and started to read and watch whatever I could find on the subject. Upon watching the Gigaohm…

Article: Using Data Mining Techniques to Predict the Winter Olympics Medal Counts

Can data mining techniques accurately predict the medal counts at the Olympics?  This question came into mind four years ago while I was watching the Winter Games in Vancouver.  I knew that a predictive model could give us an estimate of the number of medals each nation might win; but how close could we get to the actual outcomes? It was a tantalizing project…

Data Science: What goes around comes around

Many, many moons ago I began my first data science project. It involved a search algorithm for selecting the most probable mode of inheritance for a congenital anomaly given 10,000 two-generation pedigrees. Given the complexity of the algorithm I had to do my own coding: in FORTRAN ! It was tedious to say the least but I felt that I thoroughly knew the ins and outs of the methodology as a consequence writing code.

After that project I discovered a new analytical tool that promised to…

Three myths about data scientists and big data
