A Multimodal Low Complexity Neural Network Approach for Emotion Recognition
Human Behavior and Emerging Technologies, Volume 2024, Issue 1, 2024.This paper introduces a neural network‐based model designed for classifying emotional states by leveraging multimodal physiological signals. The model utilizes data from the AMIGOS and SEED‐V databases. The AMIGOS database integrates inputs from electroencephalogram (EEG), electrocardiogram (ECG), and galvanic skin response (GSR) to analyze emotional ...
