“…Researchers recruited a total of 19 adults (7 females, 12 males) from the University of Arizona in this study 20 , 21 . Participants were asked to monitor the distances travelled: short (100 virtual meters) vs long (200 virtual meters) distances while navigating in the virtual reality.…”

“…, A m ∈ P n along the geodesic that connects two points on the manifold, as illustrated in Figure 1 (B) with four data points as an example. The initial barycenter is set to be the first data point, S (1) := A 1 , and then the barycenter is updated as the middle point along the geodesic that connects S (1) and A 2 , i.e., S (2)…”

“…The core of BCI system is the classifier that classify the brain signals into one of the commands for the external devices. These brain signals are typically captured through multi-channel Electroencephalography (EEG) 1,2 , functional magnetic resonance imaging (fMRI) 3,4 , and other neuroimaging techniques, which leads to BCI data being mostly spatial and temporal. To capture the spatial and temporal pattern of BCI data, covariance matrices are extensively employed, and BCI classifiers are trained to directly classify covariance matrices in the Riemannian geometry based framework [5][6][7] .…”

“…Next are feature extraction methods such as principal component analysis (PCA) [12], fourier transform (FT) [13], [14], empirical mode decomposition (EMD) [15]- [18], wavelet transform (WT) [19]- [30] and tunable Q-factor wavelet decomposition (TQWT) [31]- [35]. Feature extraction from the raw EEG signal to train machine learning classification models can identify different states of epilepsy.…”

“…However, EMD is a time-frequency decomposition technique from a time domain perspective. The intrinsic oscillatory modes in EMD depend on the characteristics of the time scale, which is widely applied in nonstationary signal recognition [15]- [18]. To obtain sufficient information from different bands of wavelets, another method of EEG data analysis is the wavelet transform.…”
