Probabilistic Latent Variable Models as Nonnegative Factorizations

Figure 6

Illustration of the latent variable model. Panel shows 3-dimensional data distributions as points within the Standard 2-Simplex given by . 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 ).
