Learning from other subjects helps reducing Brain-Computer Interface calibration time

Fabien Lotte, Cuntai Guan
2010 2010 IEEE International Conference on Acoustics, Speech and Signal Processing  
More precisely, we propose an algorithm to regularize the Common Spatial Patterns (CSP) and Linear Discriminant Analysis (LDA) algorithms based on the data from a subset of automatically selected subjects  ...  A major limitation of Brain-Computer Interfaces (BCI) is their long calibration time, as much data from the user must be collected in order to tune the BCI for this target user.  ...  Rather, we should select a subset of subjects whose data can be used to classify the target subject's data. To do so, we propose the subject selection algorithm described in Algorithm 1.  ...
