Summary
This study introduces a novel method using electroencephalogram (EEG) complexity to automatically detect gender from emotional states. The entropy-spatial descriptors (ESDs) framework significantly improved gender recognition accuracy, offering insights into brain activity and emotions.
Area of Science:
- Neuroscience
- Biomedical Engineering
- Computer Science
Background:
- Understanding gender differences in emotional responses via electroencephalogram (EEG) is crucial for human behavior analysis.
- Existing research lacks comprehensive investigation into gender-specific EEG patterns during emotional states.
Purpose of the Study:
- To propose an automated gender recognition system using EEG complexity.
- To develop an entropy-spatial descriptors (ESD) framework for identifying gender from emotional-based EEGs.
Main Methods:
- Investigated five entropy measures as entropy domain descriptors (EDDs) to quantify EEG complexity.
- Developed an ESD framework by combining EDDs for gender identification.
- Validated methods on EEG data from 30 participants exposed to emotional stimuli (anger, happiness, sadness, neutral).
- Evaluated performance using Support Vector Machine (SVM), k-nearest neighbors (kNN), random forest (RF), and long short-term memory (LSTM) classifiers.
Main Results:
- Individual EDD features showed significant potential as gender indicators during emotional states.
- The proposed ESD framework achieved enhanced classification accuracy, particularly with the SVM classifier.
- Statistical analysis (ANOVA) confirmed the role of specific entropies in brain emotions related to gender.
Conclusions:
- The ESD framework offers a promising approach for reliable gender detection from emotional-based EEGs.
- EEG complexity analysis, particularly through ESDs, provides valuable insights into gender differences in emotional processing.
- This research contributes to understanding the interplay between gender, emotion, and brain activity.
