Abstract
Recent research indicates that compressive sensing (CS) can be successfully applied to seismic data reconstruction. It also provides a powerful tool that reduces the acquisition cost, and allows for the exploration of new seismic acquisition designs. Most seismic data reconstruction methods require a predefined nominal grid for reconstruction, and the seismic survey must contain observations that fall on the corresponding nominal grid points. However, the optimal nominal grid depends on many factors, such as bandwidth of the seismic data, geology of the survey area, and noise level of the acquired data. It is understandably difficult to design an optimal nominal grid when sufficient prior information is not available. In addition, it may be that the acquired data contain positioning errors with respect to the planned nominal grid. We propose an interpolated compressive sensing method which is capable of reconstructing the observed data on an irregular grid to any specified nominal grid, provided that the principles of CS are satisfied. We first describe the theory and implementation of this interpolated CS method. Then we illustrate this approach using synthetic and real data examples, and make comparisons to the traditional CS method. We show that the interpolated CS method provides an improved data reconstruction compared to results obtained from the traditional CS method.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
