Abstract
We present recent results on the scattering of plane waves in piecewise constant layered media, introducing a new geometric perspective. It turns out that the classical inverse scattering problem generically decouples into two separate problems. One problem is to recover a line from the magnitudes of the projections onto the line of a set of lattice points. The second problem is to determine which function best interpolates a given set of data points on the integer lattice, where the interpolating function is chosen from among the translates of a known, highly oscillatory function. In applications such as acoustic imaging it is required that this interpolation problem be solved numerically, necessitating that a solution be both stable and computationally efficient.

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
