Abstract

fetched live from OpenAlex

Noise mitigation is critical in a myriad of scientific disciplines and applications, including spectroscopy, telecommunication, and sensing. The task is particularly difficult when working in the Fourier (frequency) domain. This study presents a methodology to redistribute the energy of a spectrally periodic wave along its frequency spectrum, in noiseless fashion, to obtain a new set of waveforms with higher spectral peak power over the input noise floor. The mechanism of passive amplification is based on an elegant, powerful generalization of the spectral Talbot effect, and it enables interesting capabilities for noise reduction in important applications.

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.
