The hype about all the futuristic applications that Bayesian classifiers wil usher in is getting rather aged. But bump the hype. There’s nothing like running code. Skip Montanaro shows how easy it was to write some Python codde to apply the SpamBayes project to a real life problem where he had a large database (of concert and event information) which he needed to cull for bad data. I think this is very promising stuff.
