A brain–computer interface (BCI) is a device that enables communication between the human brain and an external device. It aims to recognize the human’s intentions from spatiotemporal neural activity typically recorded by a large set of electroencephalogram (EEG) electrodes. What makes it particularly challenging, however, is its susceptibility to errors in the recognition of human intentions, especially during motor imagery (MI). The underlying reason is the high inter-subject variance, which makes it difficult to build one universal model for all subjects.

This project aims to find a global model using hyperdimensional superposition of model weights [1]. A preliminary study showed that we can find a global model for 9 subjects on a 4-class MI dataset. In this project, you apply hyperdimensional superposition on a much larger dataset with 109 subjects. Furthermore, you will apply the same methodology on different BCI paradigms at the same time, e.g. P300 and MI, aiming for a model able to process different brain signals simultaneously.
