Illustration of the geometric mixture model used in the present work. The image shows a hypothetical set of three mixture components (C1, C2, and C3) and two mixed samples (M1 and M2) produced from different mixtures of those components. The triangular simplex enclosed by the mixture components is shown with dashed lines. To the right are the matrices M, C, and F corresponding to the example data points.
