CLASSIFYING EEG RECORDINGS OF RHYTHM PERCEPTION
Bibliographic record
Abstract
Electroencephalography (EEG) recordings of rhythm percep-tion might contain enough information to distinguish different rhythm types/genres or even identify the rhythms themselves. In this paper, we present first classification results using deep learning techniques on EEG data recorded within a rhythm perception study in Kigali, Rwanda. We tested 13 adults, mean age 21, who performed three behavioral tasks using rhythmic tone sequences derived from either East African or Western music. For the EEG testing, 24 rhythms – half East African and half Western with identical tempo and based on a 2-bar 12/8 scheme – were each repeated for 32 sec-onds. During presentation, the participants ’ brain waves were recorded via 14 EEG channels. We applied stacked denois-ing autoencoders and convolutional neural networks on the collected data to distinguish African and Western rhythms on a group and individual participant level. Furthermore, we in-vestigated how far these techniques can be used to recognize the individual rhythms. 1.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
