Abstract

fetched live from OpenAlex

This chapter talks about improving the performance of computational processes. It shows an example where we can time how long it takes to generate a set of random uniform numbers. Profiling is best used on calculations we have already discovered are “slow.” The chapter shows how it is done by wrapping a call to the Rvmmin minimizer in commands that ask for a profile to be saved. It analyzes the byte-code compiler for R. The compiler package is part of the distribution but needs to be loaded or invoked via appropriate instructions when packages are installed. The chapter demonstrates the use of the minimization of the Rayleigh quotient to find the largest eigenvalue of a symmetric matrix. One of the major parts of any iterative algorithm is deciding when it is finished, or rather when the approximation to the answer we have is “good enough.”.

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.
