Singer and music discrimination based threshold in polyphonic music
Bibliographic record
Abstract
Song and music discrimination play a significant role in multimedia applications such as genre classification and singer identification. Song and music discrimination play a significant role in multimedia applications such as genre classification and singer identification. The problem of identifying sections of singer voice and instrument signals is addressed in this paper. It must therefore be able to detect when a singer starts and stops singing. In addition, it must be efficient in all circumstances that the interpreter is a man or a woman or that he or she has a different register (soprano, alto, baritone, tenor or bass), different styles of music and independent of the number of instruments. Our approach does not assume a priori knowledge of song and music segments. We use simple and efficient threshold-based distance measurements for discrimination. Linde-Buzo-Gray vector quantization algorithm and Gaussian Mixture Models (GMMs) are used for comparison purposes. Our approach is validated on a large experimental dataset from the music genre database RWC that includes many styles (25 styles and 272 minutes of data).

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
