Abstract
Summary We present an algorithm for simultaneous data deblending and source interpolation. The algorithm adopts the projected gradient descent method with a denoiser that acts as a projection to iteratively deblend and reconstruct shots onto a regular grid. We study two problems. Data are assumed to lie on a regular grid with missing shot positions in the first problem. These data were obtained by simple nearest neighbour interpolation (binning). The Multichannel Singular Spectrum Analysis (MSSA) filter is used as the denoiser. In the second case, we honour true spatial shot positions and adopt Interpolated MSSA (I-MSSA) as the denoiser. We show the superior performance of the deblending and reconstruction algorithm when the I-MSSA projection is adopted. In essence, we propose an algorithm that allows one to deblend and reconstruct shot positions. Hence, one can achieve extra acquisition savings by blending sources and source decimation.

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
