Can the rica function return an estimate of the unmixing matrix?

9 views (last 30 days)
Hi, I am experimenting with MATLAB's rica algorithm and the conventional fastICA algorithm (open-source, MATLAB source code). I have 2 signals with mixed sine waves as input data and want to compare both algorithms' estimate of the unmixing matrix W given the input data. Essentially, this is the cocktail party problem with two sources and two mixed signals.
After reading the documentation on rica and the ReconstructionICA object, I am still very confused. Does the TransformWeights property of the ReconstructionICA object relate to W? If not, how can I calculate W with rica?

Yes, it does, if you have RICA reduce your original features to just 2, see this example in our doc: https://www.mathworks.com/help/stats/extract-mixed-signals.html
