Pandemic and Epidemic Models with Mathematica

Posted in anthropology, biology, data mining, mathematica, musings, science, social networks, social science, speculation, tagged , , , , , , , on May 6, 2009 | Leave a Comment »

In case you ever wanted to see some nice theory + simulation + visuals here’s a collection of nice Mathematica based explorations:
Jeff Bryant with Ed Pegg’s code on Influenza Epidemic modeling
Disease spread demonstration
SARs spread demonstration/animation
Oh, and I thought this was interesting… a nice PPT on pandemics.
I wonder if the swine flu spread through social networks [...]

Wolfram|Alpha? – Computing we were promised 50 years ago?

Posted in Statistics, automata, behavior, data mining, decision theory, economics, mathematica, mathematics, product development, programming, software, web 2.0, tagged , , , , , , on March 5, 2009 | 1 Comment »

An interesting approach to knowledge mentioned in Stephen Wolfram’s blog:
But what about all the actual knowledge that we as humans have accumulated?
A lot of it is now on the web—in billions of pages of text. And with search engines, we can very efficiently search for specific terms and phrases in that text.
But we can’t compute [...]

webMathematica and MacOS X

Posted in mathematica, mathematics, programming, software, tagged , , , , , , on February 7, 2009 | 2 Comments »

Getting webMathematica working on MacOS X was not entirely trivial, even with decent install instructions.
Here’s what you’ll need to avoid wasted time in getting set up:

Install Mathematica first, ideally the latest version
Your java should be fine provided you’re on OS X 10.4.11+, but double check your java -version looking for 1.5+
Use tomcat6.  I tried glassfish, [...]

Wolfram Mathematica Home Edition

Posted in cellular automata, computation, computer science, data mining, mathematics, programming, software, tagged , , , , , on February 7, 2009 | 5 Comments »

Wolfram Mathematica Home Edition is available.  It’s a $295 fully functional version of Mathematica 7.
Everyone should consider getting a copy.  No, really, everyone.  
What mathematica can help you do is as useful as word processing.  I know, that sounds crazy.  How could scientific computing be for everyone?
Consider the amount of math, data mining and research one [...]

What Is Functional Programming?

Posted in Uncategorized, tagged , , , , on December 21, 2008 | Leave a Comment »

Here’s a nice intro to functional programming on Dr. Dobbs.
In any functional programming language, you are likely to encounter these features:
* First-class functions, or higher-order functions: Functions can serve as arguments and results of functions.
* Recursion as the primary tool for iteration.
* Heavy use of pattern matching, although technically it is not a defining feature [...]

Image Recognition in Mathematica 7 – Cheaper than a VC Backed Start Up!

Posted in mathematics, media, product development, software, voice recoginition, web 2.0, tagged , , , , on December 10, 2008 | Leave a Comment »

Here’s a secret.
You don’t need VC money to build a kickass image/video/sound recognition search engine like Like.com or that silly iphone app in the commercials.
A copy of mathematica and this blog post on Mathematica 7s image manipulation features should get you well on your way.
Really folks. Mathematica has this out of the box.
Now, you probably [...]

Moebius Transformations and the Usefulness of Visualization

Posted in mathematics, media, tagged , , , , , , , on November 22, 2008 | 1 Comment »

Here’s an amazing video on YouTube (this will be old news to many people, as the video got popular last year at this time).  I got the back story on this bad boy from American Mathematical Society monthly mag, Notices.  You can get more detail on the video and the creators at IMA.
It’s a video [...]

Mathematica is rad.
Machine learning is also rad.
Check out these fine demos and code files for some nice informatics and machine learning ideas.

Church Rosser Theorem

Posted in computation, mathematics, new kind of science, tagged , , , , , on July 16, 2008 | Leave a Comment »

This is one fun little theorem.
Basically… if symbolic systems terminate (program halts/gives output), the terminating expression is independent of how the rules were applied.
You get “confluence” out of this.
You probably are thinking, “and so what does this have to do with my life?”
a) maybe nothing if arithmetic never enters your life (unlikely)
b) it’s extremely [...]

Simulating Boxing Matches with Cellular Automata

Posted in analysis of behavior, automata, data mining, economics, social science, tagged , , , , , on May 4, 2008 | 1 Comment »

I need a real world situation involving a rich, but somewhat contained behavior space to attempt a cellular automata model.
In watching the rather lame De La Hoya and Forbes fight last night (gosh, I haven’t seen a blockbuster match in 3-4 years and I watch a lot of boxing!) it occurred to me that boxing [...]
