Abstract

fetched live from OpenAlex

We propose an ensemble of classification models formed using different assessment metrics. For a given metric, a classifier performs feature selection and combines models based on different subsets of feature variables which we call phalanxes. This first step, which employs the algorithm of phalanx formation, identifies strong and diverse subsets of feature variables. A second phase of ensembling aggregates classifiers across diverse assessment metrics. The proposed method is applied to protein homology data to mine homologous proteins, where the feature variables used for developing classifiers are various measures of similarity scores of proteins, and found robust for ranking both evolutionary close and distant homologous proteins.

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.
