Abstract

fetched live from OpenAlex

.In this paper we study the stochastic control problem of a partially observed (multidimensional) stochastic system driven by both Brownian motions and fractional Brownian motions. In the absence of the powerful tool of Girsanov transformation, we introduce and study new stochastic processes which are used to transform the original problem to a "classical one". The adjoint backward stochastic differential equations and the necessary condition satisfied by the optimal control (maximum principle) are obtained.Keywordsfractional Brownian motionpartial observationmaximum principlebackward stochastic differential equationsYoung integralrough path integrationCampbell–Baker–Hausdorff–Dynkin formulaMSC codes60G1560H0760H1065C30

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.
