Abstract

fetched live from OpenAlex

We develop a variational inequality approach for the inverse problem of identifying a stochastic parameter in a stochastic partial differential equation. An iteratively regularized projected stochastic gradient scheme for variational inequalities posed in a Hilbert space is proposed. By employing the martingale theory, we give a complete convergence analysis for the iterative scheme under weaker conditions on the random noise than those commonly imposed in the available literature. Preliminary numerical results on the inverse problem demonstrate the efficacy of the developed framework.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
