Feature Scaling Beats Architecture Choice in Offline Respiratory Screening for Low-Resource Clinics
View original on arxiv.orgOverview
arXiv:2610.33030v1 Announce Type: new Abstract: Deep models are the usual choice for respiratory sound classification, but in clinics without GPUs or connectivity that choice carries a cost. We compare classical and deep classifiers on a five-class respiratory-sound corpus of 1,211 clips (asthma, COPD, pneumonia, Bronchial, healthy) from 201 patient groups, with a 3.86:1 class imbalance, using pre-registered patient-grouped cross-validation (25 runs per configuration). An SVM over 30 summary fea
