Summary

• CCA spatial filter becomes spatially smooth to give robustness in short signal length condition

Methods

• 2 targets, 8 Hz or 12 Hz in the flickering session for 3 seconds
• paid attention to the target stimulus either with a gaze (overt condition) or without (covert condition)
• total number of trials per overt/covert condition was 48 trials

Results

• better classification accuracy even if the signal length is short

Comments

• very short paper
