Area of Science:

  • Neuroscience
  • Signal Processing
  • Bioinformatics

Background:

  • Emotional regulation is crucial during self-isolation to prevent mood swings.
  • Electroencephalography (EEG) signals offer a viable method for efficient emotion recognition.
  • Brain rhythm sequencing, inspired by bioinformatics, has been previously used for seizure detection.

Purpose of the Study:

  • To develop an efficient method for emotion recognition using EEG signals.
  • To identify optimal asymmetric features from brain rhythm sequences for accurate emotion classification.
  • To enable the development of portable emotion-aware devices for self-isolation scenarios.

Main Methods:

  • EEG data was analyzed using a brain rhythm sequencing approach.
  • Asymmetric features were extracted from sequences generated by different channel data using similarity measures.
  • The optimal feature was identified through evaluation for emotion recognition.
  • Classification was performed using a music emotion recognition experiment and the public DEAP dataset.

Main Results:

  • An optimal asymmetric feature was identified, yielding remarkable accuracy in emotion recognition.
  • Classification accuracies of approximately 80-85% were achieved using minimal channel data (one pair of symmetrical channels).
  • Emotion recognition demonstrated strong individual characteristics, suggesting the need for subject-dependent approaches.

Conclusions:

  • Brain rhythm sequencing with optimized feature extraction provides an efficient method for emotion recognition from EEG.
  • The approach allows for high accuracy with fewer resources, making it suitable for portable devices.
  • This novel method offers a promising pathway for future emotional applications, particularly during self-isolation.
