Abstract

fetched live from OpenAlex

The proposed fast transform is originated from the Haar wavelet. The N-point (N=2 power d) fast transform requires no multiplications in case d is even, and N real multiplications with constant in case d is odd, and it uses at least 33 percent less real additions than the Fast Fourier Transform. The proposed fast transform is developed to reduce complexity of Wavelet Packet Multiplexing (WPM). The same fast transform algorithm can be used for both multiplexing and demultiplexing of data streams. Simulations show that multi-carrier wireless communication systems can profit from use of WPM based on the proposed transform, because, in terms of complexity, WPM outperforms the most used now-a-days Orthogonal Frequency Division Multiplexing (OFDM).

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.

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.
