This study introduces an online infomax algorithm for artifact removal in electroencephalogram (EEG) signals. The proposed algorithm demonstrates effective performance in artifact removal and convergence, even in complex, time-varying systems.

Area of Science:

  • Signal Processing
  • Biomedical Engineering
  • Machine Learning

Background:

  • Electroencephalogram (EEG) signals are crucial for neurological studies but are often contaminated by artifacts.
  • Artifact removal is essential for accurate EEG data analysis.
  • Existing methods, like batch infomax, may not be optimal for real-time applications.

Purpose of the Study:

  • To propose and investigate a novel online infomax algorithm.
  • To evaluate the performance and properties of the online infomax algorithm.
  • To compare the online infomax algorithm with the batch version for artifact removal in real-life EEG signals.

Main Methods:

  • Development of an online infomax algorithm.
  • Application and comparison of both online and batch infomax algorithms.

Related Experiment Videos
