Outline

This paper systematically reviews the early studies of self-supervised learning-based EEG basic models (EEG-FMs) that process electroencephalography (EEG) data. By analyzing 10 early EEG-FMs, we find that most of them use Transformer-based sequence modeling and masked sequence reconstruction as self-supervised learning methods. However, we point out that it is difficult to evaluate the practical applicability due to the heterogeneity and limited aspects of model evaluation.

Takeaways, Limitations

Takeaways:
Presents the current status and future directions of EEG-FM research.
We present the main modeling approaches for EEG-FM and Limitations.
Emphasizes the need for standardized assessments and practical applicability assessments.
It highlights the importance of benchmarking and developing software tools through collaboration with domain experts.
Limitations:
Evaluation of EEG-FM is heterogeneous and limited.
There is a lack of validation of its practical applicability.
There is a lack of sufficient proof of the scalability of the model.
We point out the lack of principled and reliable selection throughout the EEG representation learning pipeline.
