Following on the cluster analysis of the last post, I pairwise crossed (as in cross-multiply) the resulting cluster centers, and got three reasonably-close vectors after normalization. These were:
0 x 1: (-0.36, 0.93, -0.10) 0 x 2: (-0.23, 0.97, -0.06) 1 x 2: (-0.20, 0.97, -0.14)
While satisfyingly close, I wanted to do better.

[Read More...]Once upon a time, I was a math major. I shunned engineering as not pure enough — I wanted to be a scientist. And I didn’t see that most of the really good mathematics is developed in support of other sciences, particularly physics, and engineering. Fourier analysis. Eigenfunctions. Complex numbers. And linear algebra.
