Abstract

fetched live from OpenAlex

This paper examines microphone-array-based, combined beamformer-noise canceller structures. The performance of the structures is evaluated using computer simulation as well as experimental measurements. The inter-operation of the beamformer and noise canceller is studied by measuring the SNR improvements offered by the respective components. An experimental procedure for evaluating output SNR is presented: the desired signal is captured from a set location in the recording environment. The noise signal is measured from a second (generally different) location. Results reveal an SNR improvement of up to 17 dB, and are compared to those stemming from conventional approaches

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.
