Abstract

fetched live from OpenAlex

<p>Despite several strong hypotheses on how rogue waves can be generated in idealized conditions, the real-world causes of these waves are still largely unknown. We credit this to insufficient amounts of observational data and a missing robust probabilistic framework to analyze the available data.</p><p>We address these issues by processing over 1 billion wave measurements from offshore buoys and organizing them into a comprehensive catalogue. Through a robust, machine-learning driven analysis, we then identify several characteristic sea conditions that lead to significantly higher risks to encounter a rogue wave. This yields quantitative evidence on the relative importance of the underlying physical mechanisms.</p><p>Specifically, we find that by far the most important factor is crest-trough correlation, a parameter related to spectral bandwidth, with other parameters acting as minor corrections. This has profound implications on the nature of "everyday" rogue waves, and suggests a path towards a more reliable extreme wave forecast.</p>

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.
