Untitled. Data is beautiful, data is a story. Packages. Using R to quickly create an interactive online map using the leafletR package. The Molecular Ecologist. First off, thanks to Tim and Jeremy for the invitation to write a guest post here on using R to make maps!
As a brief introduction, my name is Kim Gilbert, and I am a Ph.D. student at the University of British Columbia working with Mike Whitlock. I am broadly interested in population genetics and population structure, and am currently studying local adaptation in a tree species. If you want to know more, check out my website, where I also have this tutorial as a .pdf presentation. Okay, onward with R! And apologies in advance that the R code provided will not show color coded text (a limitation of wordpress), but I decided that it is more useful to leave as text in order to allow copying and pasting rather than insert screenshots that might look nicer but require retyping on your part.
In the field of molecular ecology we see many, many maps. Packages. Data Science - Community. Web Technologies and Services. Data Sets. Index of /ml/machine-learning-databases. Publishable Stuff.

Posted: February 19th, 2014 | Author: Manuel Lima | Filed under: Uncategorized | No Comments » As many readers might have noticed, from my first and most recent book, I’m slightly obsessed with medieval information design, and the remarkable work of many our visualization forefathers, such as Isidore of Seville (ca. 560–636), Lambert of Saint-Omer (ca. 1061–ca. 1125), or Joachim of Fiore (ca. 1135–1202).
An important figure in this context was the German historian and cartographer Hartmann Schedel (1440–1514). Information aesthetics - Data Visualization & Information Design. Principal Component Analysis step by step. In this article I want to explain how a Principal Component Analysis (PCA) works by implementing it in Python step by step.
To help you get started, we have put together a selection of the tools we use the most and that we enjoy working with.

Machine Learning (Theory) Data Mining: Text Mining, Visualization and Social Media. The Turing Test for artificial intelligence is a reasonably well understood idea: if, through a written form of communication, a machine can convince a human that it too is a human, then it passes the test.
The elegance of this approach (which I believe is its primary attraction) is that it avoids any troublesome definition of intelligence and appeals to an innate ability in humans to detect entities which are not 'one of us'. This form of AI is the one that is generally presented in entertainment (films, novels, etc.). However, to an engineer, there are some problems with this as the accepted popular idea of artificial intelligence. I believe that software engineering can be evaluated in a simple measure of productivity. Hilarymason.com. Big Data, Plainly Spoken (aka Numbers Rule Your World) Two years ago, Wired breathlessly extolled the virtues of A/B testing (link).
A lot of Web companies are in the forefront of running hundreds or thousands of tests daily. The reality is that most A/B tests fail. A/B tests fail for many reasons. Typically, business leaders consider a test to have failed when the analysis fails to support their hypothesis. Statisfaction. Statisfaction. Doing Bayesian Data Analysis. Three-Toed Sloth. "Learning Spatio-Temporal Dynamics" : Boasting about my student's just-completed doctoral dissertation. Over 2500 words extolling new statistical methods, plus mathematical symbols and ugly computer graphics, without any actual mathematical content, or even enough detail to let others in the field judge the results. On Monday, my student Georg M. Goerg , last seen here leading Skynet to declare war on humanity at his dissertation proposal , defeated the snake — that is, defended his thesis: Learning Spatio-Temporal Dynamics: Nonparametric Methods for Optimal Forecasting and Automated Pattern Discovery.
