Maximum Entropy PDF Reconstruction Code

Many of you have asked me to share my Maximum Entropy Method code for the reconstruction of density distributions. Unfortunately, I am unable to do that at the moment. In an effort to stop the email campaign that is asking me for the code, I decided to create a cgi interface for it and put it online. So here it goes...

Here is a summary of the maximum entropy method. You can access my code through the interface below. At the bottom of this page, you will find a example moments from known distributions. Use those to experiment with the code.

Usage:

• Known Moments: The set of all known moments for the unknown distribution. Enter one moment per line in the textarea below. Moments are assumed to be integer moments and are given as m0, m1, m2, etc...
• Number of Moments: Specify how many moments you wish to use (from the set of known moments) to reconstruct the distribution
• Lower Bound: Specify the lower bound on the reconstructed distribution
• Upper Bound: Specify the upper bound on the reconstructed distribution
• Number of Integration Points: Has to do with the numerical quadrature algorithm. Defaults to 80,000
• Maximum number of Iterations: specifies the number of internal iterations of the nonlinear solver
• Tolerance: Specifies the nonlinear solver tolerance
• Finite Difference Jacobian: Use finite difference to compute the Jacobian matrix
• Discrete Distribution: Use to reconstruct Discrete distribution. NOTE: Make sure you use a realistic number of integration points!

how to move keynote from one mac to another

See:

http://geekinc.ca/moving-iwork-pages-keynote-and-numbers-from-an-old-apple-to-a-new-one/

I basically moved the following files:

• Macintosh HD:Library:Preferences:com.apple.iWork09.Installer.plist

• Macintosh HD:Library:Preferences:com.apple.iWork09.plist 

•  Macintosh HD:Library:Application Support:Keynote

• Macintosh HD:Library:Application Support:iWork ’09

• Macintosh HD:Applications:iWork ’09

My New Project: Show Me the Math

Please join me in celebrating the launch of my new project "Show Me the Math", a journal purely dedicated to mathematical derivations of physical and numerical stuff. I will no longer post derivations on pleasemakeanote as those will go to showmethemath. I will start porting and improving the current derivations to the new blog as time goes by.

Thank you all for your support,
yNot

latex2html Underline Equations and Formulas

I recently tried to use latex2html to export a few of my tex documents to html. I simply used

latex2html main.tex

but I ended up with a bunch of unsavory lines under all of my equations. Upon googling things a bit, I found the following solution that worked for me:

https://ccrma.stanford.edu/~jos/webpub/Eliminating_Black_Rules_Equation.html

On my mac, here's what I did:

1. search for the file alt-rule.pro (on my Mac, I opened the folder /usr and searched for it there. the file was located under: /usr/local/texlive/2012/texmf/dvips/config/
2. edit the file as suggested by the link above. i.e., replace
   gsave newpath   /ruleY X /ruleX X
   with
   gsave newpath
   transform round exch round exch itransform
   /ruleY X /ruleX X

and Voila!
