Random ramblings

2001-07-16 16:08:06+00 by Dan Lyke 2 comments

I need to get a diary going so I can feel better about venting and spewing in self-indulgent ways. Spent the weekend trying to understand Principal Component Analysis, struggling through Eigenvalues and Eigenvectors, when I opened Numerical Recipes in C, looked at the Jacobi method for solving the Eigen* problem and realized that I could just combine several steps in the analysis and avoid a whole bunch of the math (although I'm probably doing all the same arithmetic). It's still going to be roughly O(n3), but I'll get the critical information out in the order that I care about it, and since the whole point of this is throwing away the low information axiis, that could reduce one of the terms from a few thousands to two or three.

And I need to work on my flirting skills, especially as a couple, 'cause Ahlia at Alfy's[Wiki] is cuuuuuute. And as always, dinner at Alfy's[Wiki] was very enjoyable.

And these two topics have no business in the same post! Unless, of course, Ahlia is studying at night to become a mathematician. Otherwise, math beyond 1 + 1 = 2 is completely out of place in flirting.

You know the one about the mathematicians and the waitress?
