Vowel Imagery Decoding toward Silent Speech BCI Using Extreme Learning Machine with Electroencephalogram

Figure 5

Averaged classification accuracies over all pairwise classification using a support vector machine with a radial basis function kernel (SVM-R), extreme learning machine (ELM), extreme learning machine with a linear kernel (ELM-L), and extreme learning machine with a radial basis function kernel (ELM-R) for all five subjects.
