A Novel Design of 4-Class BCI Using Two Binary Classifiers and Parallel Mental Tasks

Figure 4

The map between the positive output of the 4 one-versus-all LDA classifier and the 4 classes of the conventional BCI (also see Table 1) in paradigm A. For example, LDA 3 is a binary classifier discriminating class 3 against all remaining classes (1, 2, 4). If its positive output is the largest among all the four binary classifiers, the class of the conventional BCI will be regarded as 3.
