Abstract

fetched live from OpenAlex

A method based on support vector machines (SVMs) is proposed to detect rain from X-band marine radar images. First, each image is labeled as rain-free or rain-contaminated according to the simultaneous rain rate data provided by a rain gauge. Then, feature vector is extracted from each image, which consists of the normalized histogram bin values. The SVM-based rain detection model is trained and tested using radar data collected in a sea trial in the vicinity of the east coast of Canada. Compared to the zero pixel percentage (ZPP) based method, the detection accuracy are shown to be improved by the proposed method. In addition, the method is robust for a wide range of bin number values even with limited training samples.

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.
