Abstract
A three dimensional (3-D) spatio-temporal analog signal processing scheme is presented for the selective removal of off-dish interference and noise from focal plane array (FPA) received signals. The method exploits specific geometrical properties of the 3-D spatio-temporal frequency spectrum of FPA signals to perform the filtering operation. A 3-D infinite impulse response (IIR) filter having a cone-shaped filter passband in the 3-D spatio-temporal frequency space is employed to extract the spectra of desired FPA signals while rejecting the spectral components from undesired off-dish interference and coupled noise from front-end electronics. A proof-of-concept example is provided by considering the filtering operation in 3-D spatio-temporal frequency domain.

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
