ica-tutorial

Introduction

Tutorial on Blind Source Separation (BSS) and Independent Component Analysis (ICA).

The repository is structured as follows:

• the Tutorial on ICA.ipynb Jupyter notebook contains the actual tutorial;
• the ica_tutorial folder contains the utility code used in the notebook:
  • the ica package contains the implementation of ICA algorithms (i.e., FastICA and EFICA);
  • the preprocessing package contains common preprocessing steps (e.g., filtering and whitening);
  • the rls package contains the implementation of Recursive Least Squares (RLS) algorithms for ICA and whitneing;
  • the plotting package contains functions for plotting;
  • the utils package contains utility functions.

Environment setup

The code is compatible with Python 3.7+. To create and activate the Python environment, run the following commands:

python -m venv <ENV_NAME>
source <ENV_NAME>/bin/activate

Then, from within the virtual environment, the required packages can be installed with the following command:
