Abstract

fetched live from OpenAlex

Higher order cumulant analysis is applied to the blind identification/equalization of linear moving average (MA) channels with QAM data. To identify the MA parameters of channels, a higher order cumulant fitting approach is adopted. The set of channel parameters is obtained by simulated annealing optimization, which overcomes the problem of a multimodal cost function in channel identification. The coefficients of a linear equalizer are obtained using the channel inversion algorithm. Batch type as well as batch recursive algorithms are investigated. The feasibility and convergence behavior of the proposed algorithms are examined by means of computer simulations.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>

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.
