Practical Bayes: Variational vs. Sampling | Graham's Research Blog
Machine Translation, Speech Recognition, Machine Learning, and the like. Recently Bayesian methods (particularly non-parametric Bayesian methods) have been widely used in unsupervised learning for NLP, as they provide a principled way to balance model complexity and expressiveness. There are two major techniques for learning Bayesian models: Variational Bayes (VB), and Gibbs Sampling. For more det

The Bayesian Songbook
The Bayesian Singalong Book Abstract Recently updated for Valencia 9 (June 2010), this is a collection of some of the most well-known Bayesian Songbook classics, dating back to the very earliest days of the Valencia meeting cabarets. Like many "greatest hits" collections, it of course omits a lot of great material in order to make room for better-known "hits," some of which seem to smack of commer

Bayesian linear regression – Mailund on the Internet
Mailund on the Internet Computer science, bioinformatics, genetics, and everything in between I’m currently reading Bayesian Statistics: An introduction by Peter M. Lee, and today I’m reading chapter 6 on linear regression. I decided to play around with one of the examples in R. The model is just linear regression as we know and love it, that is we have explanatory variables $$x_i$$ and dependent

The software offered below was written by Paul O. Lewis unless otherwise indicated. Most are useful for teaching concepts in statistics or phylogenetics, and all are free for downloading. Unfortunately (as one person doing this in my spare time) I can offer very little in the way of support for these programs. You are welcome to email me; however, I cannot guarantee that I will have time
