Abstract

fetched live from OpenAlex

In a previous paper by the same authors in the current conference series [1], an interesting relation was derived which showed that the significant wave height Hsis linearly proportional to the standard deviation of the received time series from a monostatic HF radar. In the current paper we use this relation along with methods from the field of volatility modeling, which is often used in financial mathematics, to provide accurate estimates of significant wave height. We demonstrate on field data from Argentia, Newfoundland, Canada that the use of such methods gives slightly more accurate Hsestimates than using a simple windowed variance calculation.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
