Abstract (in Japanese) (See Japanese page) 
(in English) Motor imagery based brain computer interface is a technique to control some device (e.g., wheelchair) through motor imagery brain signals. In order to achieve this, supervised learning techniques, which use enough numbers of training samples, are often applied to learn the parameters of spacial filter. However, the recording process of the training samples of motor imagery brain signals requires great time and effort. Our goal is to reduce this load by proposing new parameter learning methods.
In this paper, we propose new algorithms to learn the parameters of common spatial pattern filter by using dataset of multiple subject for the motor imagery based brain computer interface, called the ``inter-subject common spatial pattern (ISCSP) filter''. Use of the ISCSP filter can reduce the load of user to record user's motor imagery brain signals, since it needs to use a few or no samples of user's motor imagery data. In experiments, we show the validities of our methods.
