Estimating Sparse Sources from Data Mixtures using Maxima in Phase Space Plots
Malcolm Woolfson
In Blind Source Separation (BSS), one estimates sources from data mixtures where the mixing coefficients are unknown. In the particular case of Sparse Component Analysis (SCA), eac…

Comparison of Clustering Methods for Extraction of Uncorrelated Sparse Sources from Data Mixtures
Malcolm Woolfson
There is an extensive set of methods to determine sparse sources from mixtures where the mixing coefficients are unknown. Each method involves plotting N sets of mixed data against…

Extraction of Uncorrelated Sparse Sources from Signal Mixtures using a Clustering Method
Malcolm Woolfson
A blind source separation method is described to extract sources from data mixtures where the underlying sources are assumed to be sparse and uncorrelated. The approach used is to…
