Abstract

fetched live from OpenAlex

In this paper we consider an inverse problem for a class of nonlinear stochastic differential equations whose drift and diffusion parameters are unknown. We introduce a class of function spaces and put a suitable topology on such spaces and prove existence of optimal drift and diffusion parameters. We present also necessary conditions of optimality including an algorithm and its convergence whereby one can construct the optimal drift and diffusion parameters.

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.
