Packt Publishing has provided Chapter 10 of their forthcoming Hadoop MapReduce Cookbook for DZone Readers, covering Hadoop and Amazon ElasticMapReduce.
I have a strong opinion, and a rule for using printf(): don't use it.
Jim Guszcza from the Wisconsin School of Business leads this tutorial on Actuarial analytics with R.
David Mease's "Statistical Aspects of Data Mining" course, taught a few years back at both Stanford and Google, is a great introduction to data mining and R.
In this data link roundup from Arthur Charpentier, there's more on Reinhart-Rogoff, a look at "reverse-causality," plus: what percentage of the world population is actually online?
The speed with which the Boston Marathon bombing suspects were identified was a remarkable sign that we’re in the age of ubiquitous photos and video of the public square, albeit at a major international event.
Lots of data news lately: Arthur Charpentier's roundup covers Reinhart-Rogoff, Kaggle, what algorithms tell us about the language of news, and much more.
Today: Mozilla's pluggable collaboration tool, CISPA, homemade drones, a radical new CSS best practice, and Code Monkey Saves World.
I needed to compute the higher moments of a mixture distribution for a project I’m working on. I’m writing up the code here in case anyone else finds this useful. (And in case I’ll find it useful in the future.)
Eric Siegal, author of the recent Predictive Analytics: The Power to Predict Who Will Click, Buy, Lie, or Die, takes on eight Big Questions.
In the early days of data warehousing, there was a raging debate between two architectural approaches. There was a camp that advocated Ralph Kimball’s federated data mart architecture, and a camp that advocated Bill Inmon’s enterprise data warehouse architecture.
Let’s take our new knowledge for a test drive with this puzzler: Why would adding a field to qf cause our result set to actually shrink in size?
I first heard about Blaze from NumPy’s original developer’s blog back in December 2012. Recently InformationWeek announced that DARPA was funding the project to the tune of $3 million dollars.
Not so long ago, businesses didn’t care about information outside the normal structure of trusted outlets like print media, trade journals, academic research and other trusted system-generated information.
If you are working on Big Data and its bleeding edge technologies like Hadoop etc., the primary thing you need is a "dataset" to work on.
Nicolas Dugué and Anthony Perez from the University of Orleans introduce new techniques to detect social capitalists on Twitter using Graph Databases.
It isn’t until we encounter flawed design that we are jolted out of our flow and forced to make choices that don’t seem to fit with either our expectations or the natural course of our activity.
If you’ve been struggling to get Python adopted at your place of work, this brochure might help as it showcases how Python is used in business in various fields from industry and science to education and government.
For instance, the social networks of the Iliad and Beowulf look more like actual social networks than does the social network of Harry Potter. Real social networks follow a power law distribution more closely than do social networks in works of fiction.
I travelled to Ireland last week, to attend the second meeting of the European Data Forum (EDF). The EDF provided travel support for my trip, and I am grateful to them for that.
Today’s facial recognition software lies at an interesting intersection of three concepts: How long things are stored for, pictures in which a person appears, and people who can recognize faces in a photo (and tag them).
GIS, an acronym that brings joy to some and strikes fear in the heart of those not interested in buying expensive software. Luckily fight or flight can be saved for another day because you don’t need to be a GIS jock with a wad of cash to work with spatial data and make beautiful plots.
A few months ago, I did published a post on negative values in triangles, and how to deal with them, when using a Poisson regression (the post was published in French). The idea was to use a translation technique...
Recently I was puzzled by some behavior Solr was showing me. I scratched my head and called over a colleague. We couldn’t quite figure out what was going on. Well Solr is open source so… next stop – Debuggersville!
