Abstract

fetched live from OpenAlex

This chapter defines various factors and measures in order to provide ways to reliably evaluate the quality of pattern recognition without and with rejection mechanisms. It illustrates several experimental studies in which the authors present how to evaluate the quality of native pattern recognition with foreign pattern rejection. For better understanding of how quality of classification with rejection should be measured, parameters and quality measures are adopted that are used in signal detection theory and in statistics. Classification with rejection is aimed at the maximization of all mentioned measures. Those measures complete discrimination between native and foreign patterns and classification of native patterns into respective classes. The chapter presents a confusion matrix, which serves as a way to visually present the results. It presents an evaluation for two pattern processing schemes: pure classification (without rejection) and classification with rejection applied to native patterns only.

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.
