Abstract

fetched live from OpenAlex

Runge-Kutta methods are one of the fundamental techniques in scientific computing.They are used to compute numerical solutions in a step-by-step fashion for ordinary differential equations (ODES) and also, via the method of lines, for partial differential equations (PDEs).By sharing information, embedded Runge-Kutta methods execute two Runge-Kutta schemes simultaneously while incurring minimal additional cost.Traditionally this is done for the purpose of actively selecting step-sizes for error control.However, in this thesis, we Contents ...

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.
