New ML method achieves high fuzzy accuracy for skin tone classification using PPG signals

Researchers have developed a new method to classify skin tone using photoplethysmography (PPG) signals, achieving high "fuzzy accuracy" by allowing predictions to be off by one class. This approach addresses the subjectivity inherent in manual skin tone labeling, which typically results in standard accuracy rates between 40-55%. The study explored three machine learning techniques, with a fuzzy cross-entropy loss function applied to raw PPG signals yielding the best results, demonstrating that PPG signals can discern skin tone.

IMPACT This research could lead to more accurate and objective skin tone classification in wearable health devices, potentially improving health monitoring for diverse populations.

    Fuzzy Accuracy Compensates for Label Subjectivity in Classification of Skin Tone Using Wearable Photoplethysmography Signals

    arXiv:2608.18969v1 Announce Type: new Abstract: We consider the problem of classification of skin tone using photoplethysmography (PPG) signals with labels of the ordinal six-class Fitzpatrick skin tones. A typical accuracy for this task is a poor 40-55 %. However, the labels are…
