arXiv:2605.24921v1 Announce Type: new Abstract: A central challenge in electroencephalography (EEG) foundation modeling is learning transferable representations across recordings with diverse tasks, montages, references, and spectral characteristics. Existing masked modeling approaches often rely on broadband continuous patches or a single discrete representation, which may underrepresent frequency-specific activity. This paper proposes BandVQ, a band-wise vector-quantized EEG foundation model that decomposes EEG into delta, theta, alpha, beta, and gamma bands, trains an independent VQ-VAE tok
This development leverages recent advancements in large language models and vector quantization techniques, applying them to the complex domain of EEG data analysis, indicating a growing trend in multimodal AI.
Improving the transferability and specificity of EEG representations could unlock significant progress in brain-computer interfaces, neurological disorder diagnosis, and cognitive enhancement technologies.
The ability to independently model frequency-specific brain activity in EEG foundation models could lead to more nuanced and accurate interpretations of brain states compared to broadband approaches.
