The study of point cloud data sampled from a stratification, a collection of manifolds withpossible different dimensions, is pursued in this paper. We present a technique for simultaneously soft clustering and estimating the mixed dimensionality anddensity of such structures. The framework is based on a maximum likelihood estimationof a Poisson mixture model. The presentation of the approach is completed with artificial and real examples demonstrating the importance of extending manifold learning to stratification learning.
