Abstract

fetched live from OpenAlex

In a previous paper, the authors showed that up to first-order, the significant wave height from a patch of the ocean is linearly proportional to the standard deviation of the received electric field from that patch using a High-Frequency Surface-Wave radar. In previous work, this was demonstrated and verified, by using volatility estimation methods, e.g. from financial mathematics, to verify that indeed this linear proportionality relation roughly holds. In this paper, we show that estimation based on linear proportionality may also be used to improve estimates of significant wave height when measurements are missing from a high-frequency surface wave radar (HFSWR). This is demonstrated using field data from Argentia, Newfoundland, Canada, and thus may potentially be used to increase reliability of estimated ocean wave parameters from HFSWR systems which may not be continuously operational due to transmission or other technical issues.

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.
