Abstract
This article is about the comparison of subject-specific, cross-subject and adaptive classification. The project is based on the research of Alex Brandmeyer et al. who used subject-specific classification for event-related potential (ERPs). The comparison is done with the data from his researched. In the previous research participants had to fulfil an auditory oddball task with visual feedback. The brain responses were measured with an electroencephalography (EEG). The expectations were that cross-subject and adaptive classification would behave worse than subject-specific. In fact the results showed that cross-subject and adaptive classification behave equal and both had a similar accuracy as subject-specific classification. Summing up, we concluded that adaptive classification has the most potential in use; first the accuracy is high and second it can cover also brain specific responses in individuals.
