In this talk, we take the unifying view of systems interacting over communication networks as distributed computing systems and propose to study them as networked control systems. We first show that a popular algorithm for distributed averaging can generate a collective global complex behavior when the inter-agent communication happens over unre...

The graphical model formalism allows to describe multivariate probability distributions using a graph where random variables are represented by nodes, and the absence of an edge corresponds to conditional independence. While this formalism is very general, the corresponding maximum-likelihood problem is often challenging numerically. In addition...

We present a formulation for coupled solutions of fluid and body dynamics in problems of biolocomotion. This formulation unifies the treatmentat moderate to high Reynolds number with the corresponding inviscid problem. By a viscous splitting of the Navier€“Stokes equations, inertial forces from the fluid are distinguished from the viscous forces...

The problem of computing the best multilinear low-rank approximation of a tensor can be formulated as an opimization problem on a product of Grassmann manifolds (by multilinear low-rank approximation we understand an approximation in the sense of the Tucker model). In the Grassmann approach we want to find (bases of) subspaces that represent the...
