Abstract
Abstract Seismic data spatial trace interpolation is one of the most important issues in seismic data processing. In this paper, a novel Fourier transform based algorithm is proposed, which can reconstruct both uneven and aliased seismic data. We formulate band‐limited data reconstruction as a minimum norm least squares inverse problem where an adaptive DFT‐weighted norm regularization term is used. The inverse problem is solved by the preconditioned conjugate gradient algorithm, which makes the solutions stable and convergence quick. Based on the assumption that local seismic data are consisted of finite linear events, from the sampling theorem, aliased events can be attenuated via LS weighting prediction linearly from low frequency. Three application cases are discussed on even gap trace interpolation, uneven gap filling and high frequency trace reconstruction from low frequency data traces constrained by a few high frequency traces. Both synthetic and real data numerical examples show that the proposed method is valid, efficient and applicable. This research is valuable to seismic data regularization and cross well seismic exploration.

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
