Quasi-Linear Transfer Function: A New Method for Frequency Domain Analysis of Nonlinear Systems
Hua-Liang Wei, S. A. Billings
A new concept, called quasi-linear transfer functions (QLTF), which can be used to characterize the output frequency behaviour of nonlinear systems, is introduced based on the well…
Characterising Linear Spatio-Temporal Dynamical Systems in the Frequency Domain
Hua-Liang Wei, Stephen A. Billings
A new concept, called the spatio-temporal transfer function (STTF), is introduced to characterise a class of linear time-invariant (LTI) spatio-temporal dynamical systems. The spat…
Boosted Convolutional Neural Networks for Motor Imagery EEG Decoding with Multiwavelet-based Time-Frequency Conditional Granger Causality Analysis
Yang Li, Mengying Lei, Xianrui Zhang +4
Decoding EEG signals of different mental states is a challenging task for brain-computer interfaces (BCIs) due to nonstationarity of perceptual decision processes. This paper prese…
A Parametric Time Frequency-Conditional Granger Causality Method Using Ultra-regularized Orthogonal Least Squares and Multiwavelets for Dynamic Connectivity Analysis in EEGs
Yang Li, Mengying Lei, Weigang Cui +2
Objective: This study proposes a new parametric TF (time frequency) CGC (conditional Granger causality) method for high precision connectivity analysis over time and frequency in m…
