Complex Network Analysis in Python

The Pragmatic Programmers just published my book Complex Network Analysis in Python. Recognize → Construct → Visualize → Analyze → Interpret

The book covers both elements of complex network analysis (CNA), including social network analysis, and the use of networkx for CNA. It covers not only social networks, but also product, semantic, event, interaction, and other types of networks. The book has five complete case studies based on real-world data…

Social Metrics from Parallel Narrative Objects

At times it might be desirable to determine what storylines on a narrative database contain certain key elements.  In the example below, the object “Alien Allan” is used to compile a listing of titles on the database that are in thematic agreement.  But rather than simply provide the listing of titles, the algorithm tabulates the key elements contained in these titles.  Notice that the most important elements resulting from the search do not necessarily match the elements in the submitted…

Fascinating Chaotic Sequences with Cool Applications

Here we describe well-known chaotic sequences, including new generalizations, with application to random number generation, highly non-linear auto-regressive models for times series, simulation, random permutations, and the use of big numbers (libraries available in programming languages to work with numbers with hundreds of decimals) as standard computer precision almost always produces completely erroneous results after a few iterations  -- a fact rarely if ever mentioned in the scientific…

Hacking the Autonomous Vehicle

I love it when I get feedback from a blog that I’ve written. I appreciate the different perspectives and insights that others bring to a topic of interest. 

The section of the blog that fueled the most comments stem from a scene in the movie I, Robot where Detective Spooner (played by Will Smith) is explaining to Doctor Calvin (who is responsible for giving robots human-like behaviors) why he distrusts and hates robots. He is describing an incident…

Quantitative Alienation in the Workplace

For my graduate paper, I studied perceptions of workplace stress through the critical lens of social disablement.  Writing this paper was certainly an intellectual exercise that at the time didn’t seem to have many practical applications.  I am therefore honoured to become better acquainted with the “mechanics” of quantitative alienation through my day-to-day duties.  I respect the fact that I can’t share any substantial details about my actual work processes on a blog.  It will therefore be…

Artificial Intelligence, Globalization and International Basketball

A strong declaration from a historically antagonist foe should put chills in the hearts of Americans preparing themselves for the world ahead: Russian President Vladimir Putin says the nation that leads in AI will be the ruler of the world  … The ruler of the world!

From the article (with some modification to avoid political landmines), we get the following:

“The development of artificial intelligence has increasingly become a national security…

Implication of Cloud On Data Science

Ranked as one of the best jobs to have all across the globe by Glassdoor, Data Science happens to be a field with a lot of changes and developments in store for itself. This being said it is very important to note that when it comes to data science, these changes are just not within the field itself but are also influenced by various developments around it. Most commonly noted of these developments. These developments could refer to the development of new technologies like Artificial…

Periodic Table of Binary Classification Performance Measures/Metrics

Binary classification is one of the most frequent studies in applied machine learning problems in various domains, from medicine to biology to meteorology to malware analysis. Many researchers use some performance metrics in their classification studies to report their success. However, the literature has shown a widespread confusion about the terminology and ignorance of the fundamental aspects behind metrics.

In our paper tittled "Binary Classification Performance…

The Connection between Big Data Analytics and the Internet of Things

Many today would believe that the concept of big data analytics was no more different from the concept of the Internet of things, as is the fish different from the water it swims in. Which is why you would be very surprised to know that they are actually two different things in reality. Both these concepts being big names in the industry have some significant differences among them, these differences only exist very much for the boosting of various systems and operations of a…
