This review systematically evaluates Uncertainty Quantification (UQ) methods applied to machine learning models for critical biosignals like EEG and ECG, addressing the specific challenges of low signal-to-noise ratios in medical contexts. By analyzing 53 existing studies, the paper highlights current theoretical frameworks while identifying significant gaps in how clinicians and systems interact with uncertainty models in real-world diagnostic environments. The findings offer essential guidance for researchers aiming to improve the robustness and interpretability of AI-driven medical devices and brain-computer interfaces.
Uncertainty Quantification in Machine Learning for Biosignal Applications -- A Review
arXiv:2312.09454v3 Announce Type: replace-cross Abstract: Purpose: Uncertainty Quantification (UQ) has gained traction in an attempt to improve the interpretability and robustness of machine learning predictions. Specifically (medical) biosignals such as electroencephalography (EEG), electrocardiography (ECG), electrooculography (EOG), and electromyography (EMG) could benefit from good UQ, since these suffer from a poor signal-to-noise ratio, and good human interpretability is pivotal for medical applications. To determine how uncertainty estimation can be used for biosignal tasks, we investigate current methods, use cases, applications, evaluations, and uncertainty measures. Methods: In this paper, we systematically review the state of the art of applying Uncertainty Quantification to Machine Learning tasks in the biosignal domain. All works from Web of Science, Scopus, IEEE XPlore and PsycINFO that discuss uncertainty in Machine Learning on one of the aforementioned biosignals is included. Results: We present various methods, shortcomings, uncertainty measures and theoretical frameworks that currently exist in this application domain based on the 53 reviewed papers and related literature. We address misconceptions in the field, provide recommendations for future work, and discuss gaps in the literature in relation to diagnostic implementations as well as control for prostheses or brain-computer interfaces. Conclusion: Overall it can be concluded that promising UQ methods are available, but that research is needed on how people and systems may interact with an uncertainty-model in a (clinical) environment.
