Abstract

fetched live from OpenAlex

This paper proposes an improved classification strategy using misclassified training samples. It is shown that a subset of the misclassified training set forms isolated pockets. In the proposed approach, apart from providing the parameters derived out of the training samples to a classifier, the location of these misclassified pockets is also provided. The proposed strategy overcomes any weakness a given classifier may have by changing the classification decision for a given test sample based on the location of the test sample with respect to the misclassified pockets. Three diversely different classifiers and a simple composite classifier are used to test the strategy. The proposed strategy is implemented on both simulated and real data and it is shown that a reduced error rate can be obtained when this strategy is used.

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. 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.
