EEG Based Emotion Analysis using Reinforced Spatio-Temporal Attentive Graph Neural and Context Net Techniques

Abstract

EEG-based emotion Classification is used to distinguish and observe the mental state or emotions. Emotion classification using EEG is used for medical, security, and various other purposes. There are several deep learning and machine learning techniques that are used to classify EEG emotion signals. They do not provide sufficient accuracy and have higher complexity and a high error rate. In this manuscript, a novel Reinforced Spatio-Temporal Attentive Graph Neural Networks (RSTAGNN)and ContextNet for emotion classification with EEG signals is proposed (RSTAGNN-ContextNet-GWOA-EEG-EA). Here the input EEG signals are taken from two benchmark datasets namely as DEAP and K-EmoCon datasets. Then the input EEG signals are pre-processed and the features are extracted using ContextNet with Global principal component Analysis (GPCA). After that, the EEG signal emotions are classified using Reinforced Spatio-Temporal Attentive Graph Neural Networks (RSTAGNN) method. Then the weight parameters of the RSTAGNN are optimized using Glowworm Swarm Optimization Algorithm (GWOA). The proposed model classifies the EEG signal emotions with high accuracy. The performance of the proposed method using DEAP dataset attains higher accuracy by 24.05%, 12.64%relatedto existing systems, like DWT-SVM-EEG-EA-DEAP and GCNN-LSTM-EEG-EA-DEAP respectively and the performance of the proposed system using K-EmoCon dataset attains higher accuracy 32.64%, 15.65% related to existing systems, like SigRep-EEG-EA-K- EEG Based Emotion Analysis using Reinforced Spatio-Temporal Attentive Graph Neural and Context Net Techniques on Deap and K- EmoCon Article and CAT-EEG-EA-K-EmoCon respectively.
