Abstract

fetched live from OpenAlex

Abstract At the end of every academic session, institutions around the world need to schedule final examinations for students. This entails allocating sufficient space for each course that requires it in a manner that minimizes scheduling conflicts for students taking multiple courses. The primary goal is to minimize cost associated with administering these exams-driven by the cost of invigilation staff needed. This paper explores the implementation of an MIP solver (CPLEX) in addition to Sequential Model-based Algorithm Configuration (SMAC) that exhibits potential to replace the current methods-consisting of heuristics and greedy algorithms. The approach produced promising results for both schedule optimality and faster generation, particularly on larger instances. However, due to computational power constraints, there remains a need for further testing on realistically-sized instances.

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.
