Abstract

fetched live from OpenAlex

The extraction of sea surface current from marine X-band radar data significantly affects subsequent oceanic parameter determination. Therefore, assessing the influence of diverse factors on the accuracy of current parameter estimation is critical. In this paper, motion compensation is used to optimize the current estimation results derived by the Polar Current Shell (PCS) and the normalized scalar product (NSP) algorithms. The data collected by Defence Research and Development Canada between November 24 and December 5, 2008 was used for analysis. Root Mean Square Deviation (RMSD) and correlation analysis results for both current speed and direction obtained by PCS and NSP are presented. This study explores the intricate relations between measurement errors and precipitation, wind speed, vessel speed, vessel speed change and heading change. Our analysis indicates that the accuracy of current measurement significantly decreases under precipitation and lower wind speed conditions.

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.
