Impress: A Machine Learning Approach To Soundscape Affect Classification For A Music Performance Environment
Bibliographic record
Abstract
Soundscape composition in improvisation and performance contexts involves manyprocesses that can become over- whelming for a performer, impacting on thequality of the composition. One important task is evaluating the mood of acomposition for evoking accurate associations and mem- ories of a soundscape. Anew system that uses supervised machine learning is presented for theacquisition and re- altime feedback of soundscape affect. A model of sound-scape mood is created by users entering evaluations of au- dio environmentsusing a mobile device. The same device then provides feedback to the user ofthe predicted mood of other audio environments. We used a features vector ofTotal Loudness and MFCC extracted from an audio signal to build a multipleregression models. The evaluation of the system shows the tool is effective inpredicting soundscape affect.

How this classification was reachedexpand
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; both teacher heads agree on what is shown here.
