The Study of Learning System for Infant Cry Classification Using Discrete Wavelet Transform and Extreme Machine Learning
Bibliographic record
Abstract
The learning system of infant cry is presented. This system consists of characteristics attraction technique and classification technique. The characteristics attraction of infant cry are based on Discrete Wavelet Transform (DWT) methods. Whilst the sound classification of coefficients characteristics uses Single Layer Neural Feed Forward (SLNF) as an Extreme Learning Machine (ELM). The Dunstan Baby Language (DBL) is the sound database for the proposed system. The sound database was collected from infants between birth and 6 months of age. Where the baby language groups are categorized into 5 types: "Eh", "Eairh", "Neh", "Heh" and "Owh", respectively. The accuracy of sound classification was designated at the number of hidden nodes of 10 – 50 with a training and testing ratio of 70/30. The suitable results are based on the number of epochs, accuracy and performances. The results show that the average accuracy of all discrete wavelet functions on the baby language are over 80%. The average performance of Sym2 is suitable for all baby language groups. Moreover, the average number of epochs of Bior3.1 is suitable for all baby language groups.

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.
