Enhanced Performance by Time-Frequency-Phase Feature for EEG-Based BCI Systems
Figure 6
The comparison of three different feature extraction methods: the first one is no-scaled feature chosen by MIFS feature selection criterion; the second one is scaled feature chosen by MIFS feature selection criterion; the last one is scale feature chosen by mRMR feature selection criterion. (a) The comparison using ELMs. (b) The comparison using SVMs.
