Abstract

fetched live from OpenAlex

Abstract Using a variety of quantitative implementations of Occam's razor we examine the low quadrupole, the ‘axis of evil’ effect and other detections recently made appealing to the excellent Wilkinson Microwave Anisotropy Probe (WMAP) data. We find that some razors fully demolish the much lauded claims for departures from scale-invariance. They all reduce to pathetic levels the evidence for a low quadrupole (or any other low ℓ cut-off), both in the first and third year WMAP releases. The ‘axis of evil’ effect is the only anomaly examined here that survives the humiliations of Occam's razor, and even then in the category of ‘strong’ rather than ‘decisive’ evidence. Statistical considerations aside, differences between the various renditions of the data sets remain worrying.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
