New framework reveals deep learning models' reliance on aperiodic signals

Researchers have developed a spectral audit framework to analyze deep learning models processing physiological time series like EEG and ECG data. This framework reveals that models often rely on an aperiodic signal component, which can be influenced by factors like age and pathology, rather than solely on domain-specific features. The study found this reliance to be task-dependent, impacting performance significantly in sleep-wake classification and clinical abnormality detection, and suggests that aperiodic controls should be standardized for more interpretable deep learning in this domain.

IMPACT Highlights potential confounds in physiological time-series deep learning, urging for standardized controls to improve model interpretability and reliability.

    A spectral audit framework reveals task-dependent aperiodic reliance across EEG and ECG deep learning

    Deep learning on physiological time series is interpreted through domain-specific features -- oscillatory rhythms in EEG, morphological complexes in ECG -- yet these signals sit atop a broadband aperiodic 1/f-like envelope that covaries with arousal, age, and pathology. We introd…
