| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In an EEG based Brain computer interface (BCI), a time-windowed signal having a fixed finite duration is classified into a class associated with a BCI task. The time window should be designed taking into account the duration when a user performs a task and a brain activity occurs. In order to find the appropriate length of the window that works well for BCI, this paper proposes a method for using a sparse time window being sparse in time domain. This method finds the optimal sparsification for the time window by a criterion based on a common spatial pattern method that is an effective method for feature extraction. By experiments, we show that the proposed method improves classification accuracy of BCI. |
