Abstract

fetched live from OpenAlex

In this paper, an automatic system for crackles detection and classification is developed. The proposed system is preceded by a stationary-nonstationary filter based on the wavelet packet transform (WPSTNST) which isolates the crackles from the vesicular sounds. The crackle analysis consists of three major steps: Firstly, a denoising filter is applied to suppress the stationary residual noise in non-stationary signal. Secondly, a new version of crackles detection based on the fractal dimension is presented. The advantage of this method is to detect crackles even they are week or overlapped. Finally, the extracted crackles are classified into fine or coarse crackles. The time-frequency analysis, the Prony model and matched wavelet analysis techniques are tested and compared in this paper

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.
