SVD

This article was exciting to me, as I'm both a Macintosh geek and a mathematics/computer science enthusiast. O'Reilly discusses how Apple incorporates latent semantic indexing and the singular value decomposition into their junk mail filter. Considering I just wrote a paper all about modern applications of the SVD, I was intrigued. :) Too bad the paper has long since been turned in.

(If you'd like to read this paper, contact me -- I don't think the paper is good enough to share with the entire world, but I can make exceptions.)
