Optimizing the number of electrodes and spatial filters for Brain–Computer Interfaces by means of an evolutionary multi-objective approach

作者:

Highlights:

• Optimization of channel selection and spatial filter for Brain Computer Interfaces.

• A multi-objective evolutionary algorithm simultaneously optimizes filter and channels.

• Multi-objective approach returns a set of solutions (channels vs. error tradeoffs).

• A simple threshold is encoded to select channels instead of a longer binary mask.

• Joint optimization of filter and channels performs better than only the channels.
