Abstract

fetched live from OpenAlex

Abstract Differential equation systems are often a natural way of describing sets of variables changing over time or space. For example, in controlling industrial systems, engineers consider the time course of a set of inputs and outputs for a system such as a chemical reactor with a view to developing useful feedback processes. Principal differential analysis uses functional data to estimate a system of linear differential equations that fit the data. The estimate minimizes an integrated squared error criterion. The coefficient functions that define the linear differential equation are estimated by expansions in terms of basis functions such as Fourier series or B ‐splines, and the estimates are calculated rapidly and without iteration.

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.
