Abstract

fetched live from OpenAlex

Many mathematical formulations of significant real-world technological or physical problems are based on optimization with objective functions being the sum of several functions, each with different properties. This structure allows to employ splitting methods in which the problem is split into parts that can be treated more efficiently than the full problem via gradients, projections, proximal evaluations, and resolvents. Different splitting methods-such as the alternating direction method of multipliers (ADMM), the Douglas-Rachford method, and forward-backward splitting-iteratively combine such evaluations in different ways to solve the original problem.

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.
