Researchers have developed a new adaptation strategy called Stacked LoRA to improve the performance of electroencephalography (EEG) foundation models for brain-computer interfaces (BCIs). This method addresses the challenge of inter-subject variability by splitting low-rank adaptation layers into a global adapter trained across all subjects and subject-specific adapters for individual adaptation. Experiments on multiple benchmarks demonstrated that Stacked LoRA significantly enhances motor imagery classification accuracy by effectively mitigating inter-subject variability, with the optimal balance between global and subject-specific adaptation depending on the target population.
