Researchers are exploring new methods for developing transformer-based foundation models for electroencephalography (EEG) data. One study benchmarks different positional encoding strategies, finding that task-specific approaches are necessary as no single method performs best across all tasks. Another paper proposes a multi-dimensional framework to evaluate EEG models under realistic low-resource conditions, revealing that while foundation models excel at long-context tasks, supervised models are competitive for short-window applications. A third investigation identifies a spectral bias in reconstruction-based EEG foundation models, showing they favor aperiodic and low-frequency components over oscillatory ones. Finally, a novel model called BandVQ is introduced, which quantizes EEG data into frequency bands to improve transfer learning performance. AI
