Abstract

fetched live from OpenAlex

Pattern reordering is proposed as an alternative to sequential and batch processing for online category learning.Upon detecting that the categorization of a new input is ambiguous, the input is postponed for a predefine time, after which it is reexamined and categorized for good.This approach is shown to improve the categorization performance over purely sequential processing, while yielding a shorter response time, or latency than batch processing.The latency of a typical implementation is derived and compared to lower bounds.Gaussian and softmax models are derived from reject option theory, and are considered for detecting ambiguity and triggering pattern postponement.The latency and Rand Adjusted score of reordered, sequential and batch processing are compared through computer simulation with Gaussian and Iris data sets.

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. 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.
