Abstract

fetched live from OpenAlex

This study first validates the ASGS algorithm developed in part I with an analytical solution in a simplified dynamical system and with a real storm surge event. It then assesses the computational efficiency by the ASGF method compared to the traditional method. By analyzing a realistic case, the ASGF method is shown to be three orders of magnitude more computationally efficient than the traditional method. Using the singular value decomposition (SVD) and the fast Fourier transform and its inverse (FFT/IFFT), this study further demonstrates how to compress atmospheric forcing data and how to cast the ASGF convolution as a simple and efficient regression model for data assimilation. When tested with the real storm surge event, the output from the regression model can account for 98 % of the observed variance.

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.
