- Winning the War on spam: Comparison of Bayesian spam filters .
- Fortunately, just as we seemed to be losing the war on spam, a new technique appeared on the scene after a paper by Paul Graham: Bayesian filters, our last, best hope for spam-free inboxes. ... The beauty of bayesian filtering is that the filter can be trained by each individual user simply by categorizing each received e-mail as either spam or not-spam; after the user has categorized a few e-mails the filter will begin to make this categorization by itself, and usually with a very high level of accuracy. ...
- Now, even though the basic technique is the same, several software packages exist and the problem is choosing between them; this was my problem when I decided to switch from a keyword-based filter to a bayesian filter. ...
- Since bayesian filters requires training, their accuracy will increase with time. ...
- Realizing that even bayesian filtering is not always perfect, SpamBayes implements a solution to this which turns out to work very well in practice: instead of categorizing e-mails as either spam or not-spam it adds a third category: unsure. ...
- We can see here that the basic bayesian filter is in fact more or less equal in the two packages; however, in real-world use the result of the two first graphs are more important. ...
- As we can see from the graph of missed spams where the "unsure" spams from SpamBayes are included the basic bayesian filter engine in both products seem to be about equal. ...
- Since bayesian filtering is based on statistics and probabilities there is no one correct way to do things, and only real-world testing can evaluate the quality of the filter. ...
- Several people mentioned that the Mozilla mail client actually includes a bayesian filter, and, of course, Mozilla is cross-platform. ...
- The latest release of Opera includes the "revolutionary" M2 mail client, which supposedly includes a bayesian filter. ...

- astrosun.tn.cornell.edu
- Tom Loredo's Bayesian Reprints.
- From Laplace to Supernova SN 1987A: Bayesian Inference in Astrophysics A review of the fundamentals of Bayesian inference, with a somewhat conceptual or philosophical (rather than practical) emphasis. It's a bit more polemical in places than it would be if I wrote it today, but Bayesian methods have come a long way since 1989! I provide some simple examples with the Gaussian and Poisson distribution, and outline more complicated applications. Published in Maximum-Entropy and Bayesian Methods, Dartmouth, 1989, ed. ... Available at the Washington University Bayesian Reprints site as a gzipped PostScript file or a PDF file. The Promise of Bayesian Inference for Astrophysics Discusses the difference between Bayesian and frequentist calculations, emphasizing methodological (rather than conceptual or philosophical) differences between the approaches. I use simple examples throughout, and include an introduction to Bayesian inference with Poisson counting and point processes, including a Bayesian analysis of "on/off" data, and the Bayesian counterpart to the Rayleigh test for measuring periodicity in arrival time series. ... The Return of the Prodigal: Bayesian Inference in Astrophysics This 37 page review article, including a simplified analysis of the COBE CBR quadrupole data as a case study, was prepared as an invited review for the Bayesian Statistics 5 conference in Valencia in June 1994. ... Computational Technology for Bayesian Inference A preprint of a small part of my talk on "Bayesian Inference: A Developer's Perspective," given at the 1999 ADASS conference. It provides a nontechnical 10pp survey of some of the current approaches and algorithms for computing the integrals that arise in Bayesian calculations. ...
- Bayesian Inference: A Practical Primer Slides (minus two slides illustrating MCMC results from Phillips & Smith 1996 and Sibisi & Skilling 1997) for an hour+ tutorial on Bayesian methods given as the opening talk at the International Workshop on Maximum Entropy and Bayesian Methods, Gif-sur-Yvette, France (2000). ... Bayesian Adaptive Exploration A description of the Bayesian theory of experimental design, with a "toy problem" example worked out showing how to optimally schedule radial velocity observations for estimating the orbital properties of an extrasolar planet. ... Bayesian Data Analysis with Applications in Astrophysics: A Survey Slides from a talk given at the June 2002 CDF/D0 Advanced Analysis Group Workshop at Fermilab. The talk begins with a survey/tutorial on Bayesian inference, and continues with a description of two astrophysical applications: the "on/off" problem (Poisson counting process with uncertain background), and analysis of neutrino data from SN 1987A. ... Bayesian Inference in Astronomy & Astrophysics: A Short Course Five lectures on basic Bayesian inference with applications in astronomy and astrophysics, given by invitation at the Center for Interdisciplinary Plasma Science of the Max Planck Institute for Plasma Physics in Garching, Germany, October 2002. ...

- Software for Flexible Bayesian Modeling and Markov Chain Sampling.
- This software supports Bayesian regression and classification models based on neural networks and Gaussian processes, and Bayesian density estimation and clustering using mixture models and Dirichlet diffusion trees. It also supports a variety of Markov chain sampling methods, which may be applied to distributions specified by simple formulas, including simple Bayesian models defined by formulas for the prior and likelihood. ...

- The BUGS (Bayesian inference Using Gibbs Sampling) project is concerned with flexible software for the Bayesian analysis of complex statistical models using Markov chain Monte Carlo (MCMC) methods. ...
- A knowledge of Bayesian statistics is assumed, including recognition of the potential importance of prior distributions, and MCMC is inherently less robust than analytic statistical methods. ...
