Abstract

fetched live from OpenAlex

Summary Multicomponent technology is likely to become the standard in future towed streamer surveys. Among reasons to acquire multicomponent data is to increase efficiency (deep tow) in acquisition, increase resolution (deghost) of pressure data, interpolate to a fine grid (using crossline directional measurements). One of the challenges of working with towed streamer multicomponent data is the fact that the measured low frequencies in the directional components are rather noisy mostly due to practical aspects/limitations. We present a formalism based on Green’s theorem that provides tools to reconstruct, redatum, and/or denoise these components, and/or for deghosting.

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.

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.
