Abstract
In this paper, a generalized polyphase (GP) structure based design method for Mth-band FIR filters is presented. Based on the ideal frequency response of Mth-band filters, a closed-form frequency specification for the constituent filters is derived. Thus, the design problem of an original large-tap FIR filter is simplified to that of the constituent filters of significantly reduced length. In the meantime, the time-domain interpolation constraint can easily be satisfied by leaving one constituent filter as a function of other constituent filters designed. Using the proposed approach, an interpolation filter is designed and applied to image interpolation. Simulation results show that the designed Mth-band filter gives a superior interpolation performance in comparison to the commonly used cubic spline interpolation scheme.

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
