Researchers have developed MAPA, a novel self-supervised learning method for brain-computer interfaces (BCIs) that significantly reduces the need for labeled data. MAPA utilizes masked autoencoding with spatial and relative positional encodings to learn general neural representations from unlabeled intracranial electroencephalography (iEEG) recordings. This approach achieves state-of-the-art performance on the Neuroprobe benchmark across within-session, cross-session, and cross-subject transfer learning scenarios. Specifically, MAPA's features require only a fraction of the labeled trials to reach high accuracy in new subjects compared to traditional methods. AI
