Abstract

fetched live from OpenAlex

Abstract Different Jeziorski‐Monkhorst ansatz‐based methods are unified according to how to group terms to eliminate the redundancy problem. It is found that some seemingly different methods used to do MRCC are equivalent. It is argued that the various defining equations are not entirely proper, in the sense that the proper residual condition is not satisfied. This may partially rationalize the unsatisfactory performance of the various methods for single reference systems. In contrast, the MRexpT method satisfies the proper residual condition and it is expected that it will outperform other JM ansatz‐based methods in single‐reference cases. © 2008 Wiley Periodicals, Inc.

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.
