Abstract

fetched live from OpenAlex

In this paper, we propose a flexible architecture that performs the computation of the discrete wavelet transform, requiring a small memory space and is capable of operating at high sampling rate. The architecture employs two filtering blocks to compute the transform and one buffer to store the intermediate results. Each filtering block has two processing units that operate independently in parallel using a two-phase scheduling. An efficient scheme for the synchronization of the data flow among the three blocks is provided in order to minimize the buffer size and increase the speed of operation. Verilog and HSPICE simulation results are presented to show that the proposed architecture is more efficient for the computation of a fully decomposed discrete wavelet transform with high-tap filters than some other existing architectures in terms of their areas and speed of operations.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
