Abstract

fetched live from OpenAlex

In this paper, we study the computation of Lyapunov exponents for deterministic dynamical systems via a general piecewise spline maximum entropy method. We present a comparison of computations of Lyapunov exponents between a piecewise linear, a piecewise quadratic and a piecewise cubic maximum entropy methods. In order to compute Lyapunov exponents for deterministic maps, we also compute density functions of their invariant measures via piecewise spline maximum entropy method.

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.
