This study introduces a new method using Regularized Linear Regression on electro-encephalography (EEG) signals to accurately identify brain states. The framework achieves over 90% accuracy in distinguishing between eyes open and closed states.

Area of Science:

  • Neuroscience
  • Signal Processing
  • Machine Learning

Background:

  • Inferring brain states is critical for Brain-Computer Interface (BCI) applications and neuroscience research.
  • Existing methods like Fourier Transform power analysis offer limited detail for brain state identification.

Purpose of the Study:

  • To present a novel classification framework for inferring brain states from electro-encephalography (EEG) signals.
  • To demonstrate a data-driven approach for BCI and neuroscience research.

Main Methods:

  • Developed a classification framework using Regularized Linear Regression on time-frequency decomposed EEG signals.
  • Employed cross-validation for optimal regularization parameter selection and feature selection.
  • Tested the framework on EEG data from 10 subjects performing an eyes open/closed task.
