Abstract: The utility of supervised machine learning in neurological applications has been limited because of the lack of large, labeled datasets. This is particularly emphasized in the applications that involve physiological time-series data such as EEG or PSG. At present, the labeling process is predominantly manual, and the pace of manual expert labeling cannot match the amount of clinical and research data being collected. To address this limitation, there has been a recent shift in focus towards physiology-inspired/domain-guided machine learning methods. The key idea is to utilize domain knowledge and labeled data as complementary means of supervision when designing and training machine learning models. In this talk, I will present some real-world examples of domain-guided machine learning applied to neurological diseases and discuss models built on top of core machine learning concepts such as graphical models, deep learning, and self-supervised learning.
