Abstract

fetched live from OpenAlex

Evaluation measures play an important role in machine learning because they are used not only to compare different learning algorithms, but also often as goals to optimize in constructing learning models. Both formal and empirical work has been published in comparing evaluation measures. In this paper, we propose a general approach to construct new measures based on the existing ones, and we prove that the new measures are consistent with, and finer than, the existing ones. We also show that the new measure is more correlated to RMS (Root Mean Square error) with artificial datasets. Finally, we demonstrate experimentally that the greedy-search based algorithm (such as artificial neural networks) trained with the new and finer measure usually can achieve better prediction performance. This provides a general approach to improve the predictive performance of existing learning algorithms based on greedy search.

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.
