  • independent component analysis (ICA);
  • maximum likelihood estimation;
  • algorithms;
  • infomax principle


In this chapter, the authors show how to apply maximum likelihood (ML) estimation to independent component analysis (ICA) estimation. They also show its close connection to the neural network principle of maximization of information flow (infomax).
