Abstract

fetched live from OpenAlex

We address problems resulting from the residuals obtained due to fitting models using the least squares procedures. The success of the least squares procedures depends on the assumption that the distribution of the errors resulting from fittingmodel to a set of data is Gaussian. For cases of non Gaussian errors, the least squares performance is far from being optimal. Efforts have been made to improve the performance of the least squares procedures for non Gaussian errors, and to enhance their performance for the Gaussian errors. Robust regression procedures appear to perform much better than the least squares procedures when the errors are non Gaussian and also have improved performances for Gaussian errors. We propose filters based on the Iteratively Reweighted Least Squares method, and offer computational results to illustrate the performance of the techniques.

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.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
