From confidence to caution: conformal gating for cross-session motor imagery brain-computer interfaces.

OBJECTIVE Erroneous motor imagery brain-computer interface (MI-BCI) commands can cause unintended device actions, yet standard classifiers provide no mechanism to withhold uncertain predictions. We evaluate whether conformal prediction (CP) can serve as a command gate under cross-session EEG shift, where exchangeabilit...

NEXUS-MI: Communication-Aware Federated Personalization for Gateway-Coordinated Motor-Imagery Brain-Computer Interfaces

NEXUS-MI is introduced, a gateway-coordinated federated personalization framework that treats synchronization as an explicit design variable in federated MI personalization and is motivated by joint evaluation of personalized accuracy, communication cost, update freshness, and subject-level reliability.

Slow-Fast Brain-Computer Interfaces: Preventing Neuroadaptive Overfitting in AI-Mediated Neural Interfaces

This Perspective argues that AI-mediated BCIs should be evaluated not only by decoding accuracy and task performance, but also by how AI assistance is deployed: when systems act autonomously, seek confirmation, preserve user effort or return control to the user.
