Large-scale pretraining and adaptive EEG decoding target calibration bottlenecks

A reported 50,000-hour self-supervised EEG effort achieved weeklong decoder stability without recalibration and an 11.32-BPS result, while a 31-participant closed-loop study reached 77.5% 2D and 86% 1D cursor accuracy after joint user-decoder adaptation. Mixture-of-experts P300 decoding, unsupervised functional-stage detection, and emerging clinical EEG classifiers reinforce the robustness agenda, but the largest pretraining claim and inaccessible adaptation-framework reports still need primary-study details and independent replication.
