Area of Science:

  • Neuroscience
  • Computer Science
  • Biomedical Engineering

Background:

  • Rapid serial visual presentation (RSVP)-based brain-computer interfaces (BCIs) detect event-related potentials (ERPs) for information detection.
  • Current BCI systems require time-consuming calibration for new users, hindering practical application.
  • Zero-calibration is a critical research area to improve BCI usability.

Purpose of the Study:

  • To develop a zero-calibration method for RSVP-based BCIs.
  • To address the challenge of lengthy calibration processes in BCI systems.
  • To enhance the efficiency and accessibility of BCI technology.

Main Methods:

  • Constructed an RSVP dataset with 31 subjects.
  • Proposed the ERP prototypical matching net (EPMN), a metric-based meta-learning approach.
  • Utilized prototype learning to create common ERP representations and a metric-learning loss function for distinguishing EEG and ERP prototypes.

Main Results:

  • The EPMN method achieved a balanced accuracy of 86.34%.
  • EPMN demonstrated superior performance compared to existing comparable methods.
  • The proposed method successfully realized zero-calibration for RSVP-based BCI systems.

Conclusions:

  • The EPMN method offers an effective solution for zero-calibration in RSVP-based BCIs.
  • This advancement significantly reduces the setup time and complexity for BCI users.
  • The findings pave the way for more practical and widespread adoption of BCI technology.
