Matlab

• Probabilistic models: I have put together some Matlab programs to find maximum likelihood estimates of several kinds of probabilistic models:
  • Factor analysis
  • Principal component analysis
  • Mixture of multivariate Bernoulli distributions
• Mode-finding in Gaussian mixtures (including the calculation of error bars, gradient and Hessian). For an explanation, see my page on Gaussian mixtures.
• Electropalatography: these are some tools for imaging EPG frames.
• Articulatory databases: the following tools allow you to read files into Matlab, plot animations of the vocal tract and speech, and various other things, for the MOCHA and XRMB databases:
  • MOCHAtools: for the MOCHA-TIMIT database. Example displays for utterance fsew0_001: animation and scatterplot.
  • XRMBtools: for the Wisconsin X-ray Microbeam (XRMB) database. Example displays for utterance jw11_tp105: animation and scatterplot.
  Both of them require you to install our speech analysis functions.

Databases

• A database of ear images I created for my 1995 MSc thesis on ear biometrics and ear identification.

LaTeX

• MACPcv: A LaTeX2e class file to typeset a personalised curriculum vitae. I decided to create my own CV style since none of the ones available in the web satisfied me.
• MACPremark: A LaTeX2e package to add remarks to a draft LaTeX file, such as I need to complete this section and add a bibliographic reference or Extend this proof to the complex numbers.
• MACPpreprint: A LaTeX2e package to add remarks to a preprint LaTeX file without modifying its layout, as if the text of the remarks had been typed over the paper once printed. This is useful to put online copies of papers in your web page which are exactly like the camera-ready ones published in proceedings or journals, but over which some text has been typed, such as a copyright notice, bibliographical information or page numbers.
• MACParrow: A simple LaTeX2e package to add horizontal curved stretchable arrows under and over a formula, as are common in commutative diagrams, like . There are other packages that do this and much more, like xypic, but if you just need over- and underarrows, this one is very compact and simple to use.

Emacs Lisp

• www-comand.el package: allows automatic sending of commands to certain WWW sites from inside XEmacs. It currently includes:
  • Lookup of words in the Anaya dictionaries for Spanish and English (as well as the Merriam-Webster dictionary and thesaurus)
  • Lookup of terms in Eric Weisstein's World of Mathematics and Britannica.com
  • Search for keywords in the Google and Altavista searchers
  • Validation of HTML files in the W3C HTML Validation Service
  and it is straightforward to include others. This package is a minimal modification of Tomasz J. Cholewo's webster-www package that comes in the standard distribution of XEmacs.20.x.

Initialisation files for various programs

I have dedicated quite a lot of time to perfect them through the years (and I keep improving them often, as I learn new things), so I thought they might be useful for somebody else - for example, new students in our group. If you want to use them, be sure to read through them and adapt them to your local configuration; for example, you will need to change some directory names, the email address, check for the existence of certain programs in your system, etc.

• .emacs, for the Emacs or XEmacs editors (requires the www-command.el file)
• init.el and custom.el, internally loaded by my .emacs for the XEmacs editor
• .bibtex, internally loaded by my .emacs for use with XEmacs' BibTeX mode
• .gnus, for gnus, the XEmacs newsreader
• .vm, for VM, the XEmacs mail reader
• .ctwmrc, for the CTWM window manager

You can get all the files as MACPinit.tar.gz.
