Compare bases · Eigen Hacks

Two ways to compute the eigen-news

v0 takes the SVD of the centred TF-IDF term matrix (axes are word lists by construction). v1 takes the eigenvectors of the covariance of sentence embeddings and names them through the same vocabulary. Both are varimax-rotated into named axes. Stories, sections and z-scores below are computed identically for both.

Basis	axes	articles with coordinates	section purity
v0 · term-space LSA	60	4174048	0.0%
v1 · embedding eigenbasis	60	4174048	0.0%

Section purity: share of stories carrying a human-assigned Wikipedia Current Events section whose dominant axis's majority section is their own. Labels are never used to fit either basis.

Matched axes

Axes paired by correlation of story coordinates (Kuhn–Munkres on |corr|). A negative correlation means the axes point opposite ways.
