SVD for dummies

Hey Jake,

Was just going to ask for more insight into SVD when lo and behold, I checked my commits mail and saw http://cwiki.apache.org/confluence/display/MAHOUT/DimensionalReduction.  Very nice!

Thank you!

Sorry about that. My send button got it. And i forgot to turn undo on :(

What I was about to say was:

Its a great library Jake has given. I can't wait to test it by using the
reduced vectors in clustering

Here's another source of understanding about svd.  MIT Professor Gilbert
Strang's lecture on the subject.  Strang is a fine educator and gentleman
and wonderfully clear with his explanation of the underlying geometry of
SVD.  

http://videolectures.net/mit1806s05_strang_lec29/

you can also get find Strang's lecture and others by searching "singular
value decomposition" on YouTube.
