Graph attention eeg emotion
The basic idea of SGA-LSTM is to adopt graph structure modeling EEG signals to enhance the discriminative ability of EEG channels carrying more emotion information while alleviate the importance of the EEG channels carrying less emotion information. To this end, we employ two graphic branches. See more Graph attention structure consists of two branches, i.e. trunk branch and attention branch, which are both based on graph convolution layers. The trunk branch is employed to extract … See more The loss function of SGA-LSTM is formulated as the following one: where \varPsi (I,I^p) denotes cross entropy of predicted label I^p with ground truth label I, \varTheta denotes all trainable parameters, and … See more The use of LSTM in the SGA-LSTM framework aims to capture the additional emotional features produced by the spatial topographic distribution of the EEG channels. Hence, we take the output of graph attention, i.e., … See more WebApr 13, 2024 · To solve this problem, we proposed an attention-enhanced graph convolutional network (AEGCN) for aspect-based sentiment classification with multi-head attention (MHA). ...
