Abstract

fetched live from OpenAlex

Summary Multichannel Singular Spectrum Analysis reconstruction (also named Cadzow filter reconstruction) offers a solution to the seismic data completion problem. Unfortunately, the method requires data deployed on a regular grid. Then, to apply MSSA, one first assigns seismic traces to a regular geometry via binning. The resulting volume of data contains a large number of empty bins that are reconstructed via the MSSA. We propose a modification to MSSA to avoid having to deploy the input data into regular bins. The new algorithm, Interpolated MSSA (I-MSSA), honours the exact spatial position of the seismic traces and iteratively reconstruct the data into a regular grid. The algorithm also incorporates an anti-alias operator that is required by our examples for simultaneous regularization and interpolation of 3D data with aliased and irregular trace positions.

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.
