Abstract

fetched live from OpenAlex

A neural network for the implementation of mean-gain-shape vector quantization is proposed. Mean-gain-shape vector quantization is a product vector quantization consisting of three codebooks. A counterpropagation network (CPN) is used to perform the vector quantizations. The CPN is a combination of two well-known algorithms: the self-organization map of Kohonen and the Grossberg outstar. The proposed approach is more efficient than the conventional LBG algorithm in terms of computational complexity. Moreover, the issue of optimal bit allocations is studied through extensive experimentation and interesting results are obtained.

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.
