Classifying Breast Cancer as Benign or Malignant Using RTextTools
Updated: 2012-02-12 05:08:38RTextTools has largely been used for topic classification in the social sciences. However, recent discussions with researchers at various universities have demonstrated that the package can be applied to a host of problems in the natural sciences as well.One such application is using text classification to identify breast cancer masses as benign or malignant. Using the Wisconsin Diagnostic Breast Cancer Dataset [...]RTextTools Short Course Materials
Updated: 2012-02-11 01:15:15Attached are some of the materials from the recent short course at UNC. For confidential reasons, we are unable to present all of the materials, but this is enough to get someone started. 1. Lecture; 2. Intro to R; 3. NY Times; 4. [...]Digital art by Eric Hayes
Updated: 2012-02-09 18:49:06I received this email yesterday from Eric Hayes. I like what he's up to so I thought I'd give him a plug. Good luck, Eric. My name is Eric Hayes, and I am a programmer and digital artist. I have written a software application called "Commander Crayon" which translates the elegance of mathematics to the [...]Plotting “traveling salesman problem” routes on an iPhone
Updated: 2012-02-07 16:45:45Here's something quite remarkable, from the Princeton University Press Blog: Twenty-four years ago a 2,392-city example of the TSP was solved in a 23-hour run on a super computer to set a new world record. This same problem now solves in 7 minutes on an iPhone 4 thanks to a free app: Concorde TSP Solver! [...]Disagreement on operator precedence for 2^3^4

For example, in MATLAB 2010a we have 2^3^4 = 4096 which is equivalent to putting (2^3)^4 whereas Mathematica 8 gives 2^3^4 = 2417851639229258349412352 which is the same as putting [...]A month of math software – January 2012

This series has been going for a year now and I’m very pleased to say that it’s become quite popular. In the beginning I had to trawl the web for all of the news I featured here but a sizeable percentage of it gets sent to me these [...]C and a Box of Chocolates: Video Presentations from the Wolfram Technology Conference 2011
