Abstract

fetched live from OpenAlex

A spatio-temporal (ST) three dimensional (3D) polyphase-DFT cone filter bank is proposed for the selective filtering of 3D plane waves (PWs) in which a conventionally fully decimated temporal polyphase-DFT uniform-band structure is employed in the analysis and synthesis sections. Following temporal decimation in the analysis section, the 3D signal is filtered in each band with second-order uniform-bandwidth 3D IIR beam filters. The ST-domain input-output behavior of the proposed polyphase filter bank closely approximates that of a 3D cone filter, where the cone-shaped may correspond to either stop band or the pass band of the filter bank. Experimental results are presented that confirm the performance of the proposed 3D polyphase-DFT cone filter bank as a means of selectively filtering broad band 3D PWs on the basis of their direction of arrivals (DOAs).

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

Teacher imitation

Not 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.
