Methods used for comparison

The results on healthy individuals based on our proposed techniques were compared to the results based on the following methods:

M1

Method 1 shows the results based on a tangent space-based transfer learning technique by Gaur et al ^[1].

M2

Method 2 shows the results obtained from the evaluation session from a study which uses a subject-specific multivariate empirical mode decomposition-based filtering method (SS-MEMDBF) for preprocessing and implements a Riemannian geometry (RG) framework designed separately for each subject for classification^[2]. It is also interesting to note that the implementation of M2 involves an overhead of an SS-MEMDBF for preprocessing, which increases the computational complexity and makes it challenging to perform online.

M3

Method 3 implements CSP and uses detection of the covariate shift and adaptive learning ^[3].

M4

Method 4 uses CSP on bandpass filtered EEG between 8 and 30 Hz before calculating the log variance from three pairs of filters for extraction of features and uses LDA for a binary classification problem ^[4].
