Abstract
A method of designing a class of 2-D IIR (infinite-impulse-response) filters with a variable cutoff boundary is presented. The transfer function of this class of 2-D filters has a zero-phase two-variable polynomial in z/sub 1/ and z/sub 2/ in the numerator and two separable polynomials (D/sub 1/(z/sub 1/), D/sub 2/(z/sub 2/)) in the denominator. The transformations used for changing the cutoff boundary are A.V. Oppenheim's (1976) for the numerator and spectral transformations for the denominator of the transfer function. It is demonstrated that the proposed method results in 2-D filters having better circular contours than the existing techniques. This technique also allows one to perform circular-to-elliptic transformation.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

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
