Labeling Emotion

231
Emotional labeling is a cognitive process that involves identifying and naming one's emotions, such as anger, fear, happiness, or sadness. It allows individuals to recognize and express their internal emotional states, a critical aspect of emotional regulation and communication. Labeling emotions requires more than mere recognition; it also involves drawing upon memory and contextual cues to understand the current situation and apply a corresponding emotional label. For instance, feeling...

Area of Science:

  • Neuroscience
  • Signal Processing
  • Machine Learning

Background:

  • Human emotions are complex, dynamic, and challenging to detect continuously from electroencephalogram (EEG) signals.
  • Existing methods often struggle with the non-stationary and high-dimensional nature of EEG data.

Purpose of the Study:

  • To propose an advanced signal processing mechanism for accurate emotion detection from one-dimensional EEG signals.
  • To develop a hybrid deep neural network model for robust feature extraction and dimensionality reduction.

Main Methods:

  • Continuous wavelet transform (CWT) to convert 1D EEG signals into 2D spectrograms.
  • Hybrid spatio-temporal deep neural network for feature extraction.
  • Differential-based entropy feature selection and Bag of Deep Features (BoDF) for dimensionality reduction.

Main Results:

  • The proposed method achieved high accuracy on the SJTU SEED dataset, with results reaching 96.7% for SVM, 96.2% for ensemble, 95.8% for tree, and 95.3% for KNN classifiers.
  • Demonstrated superior performance compared to state-of-the-art methods in emotion detection from EEG signals.

Conclusions:

  • The developed signal processing and deep learning approach offers a significant advancement in continuous emotion detection from EEG.
  • The method shows promise for real-world applications requiring accurate and real-time emotion recognition.
