PRISM: Exploring Heterogeneous Pretrained EEG Foundation Model Transfer to Clinical Differential Diagnosis

Researchers introduce PRISM, an EEG foundation model that demonstrates how diverse pretraining data leads to better clinical performance than narrow-source datasets. The study shows that geographically diverse EEG data outperforms larger but homogeneous datasets in medical diagnosis tasks, particularly achieving 12.3% better accuracy in distinguishing epilepsy from similar conditions.
