We propose to map a dynamic Bayesian network (DBN) to an ordered family of -shapes to improve DBNs classification power. This mission is achieved by: 1) embedding a DBN into a topological manifold and 2) applying the -shape geometric constructor to build hierarchical structures assigned to the DBN. This continuous representation of traditional DBNs as -shapes allows more information...
The Stiefel manifold comprises sets of orthonormal vectors in Euclidean space, and as such arises in a variety of contemporary statistical signal processing contexts. Here we consider the problem of estimating the state of a hidden Markov process evolving on this manifold, given noisy observations in the embedding Euclidean space. We describe an approach using sequential Monte Carlo methods, and provide...
