Figure 6: Illustration of the latent variable model. Panel shows 3-dimensional data distributions as points within the Standard 2-Simplex given by { ( 0 0 1 ) , ( 0 1 0 ) , ( 1 0 0 ) } . The model approximates data distributions as points lying within the convex hull formed by the components (basis vectors). Also shown are two data points (marked by + and × ) and their approximations by the model (resp., shown by ◊ and □).
