Approximate Joint Diagonalization and Geometric Mean of Symmetric Positive Definite Matrices
Marco Congedo, Bijan Afsari, Alexandre Barachant +1
We explore the connection between two problems that have arisen independently in the signal processing and related fields: the estimation of the geometric mean of a set of symmetri…
Riemannian Consensus for Manifolds with Bounded Curvature
Roberto Tron, Bijan Afsari, René Vidal
Consensus algorithms are popular distributed algorithms for computing aggregate quantities, such as averages, in ad-hoc wireless networks. However, existing algorithms mostly addre…
On The Convergence of Gradient Descent for Finding the Riemannian Center of Mass
Bijan Afsari, Roberto Tron, René Vidal
We study the problem of finding the global Riemannian center of mass of a set of data points on a Riemannian manifold. Specifically, we investigate the convergence of constant step…
Exact Enumeration of Two-Dimensional Closed Random Paths Using a DSP Processor
B. Afsari, N. Sadeghi-Meybodi, S. Rouhani
The aim of this paper is to show that Digital Signal Processors (DSPs) can be used to efficiently implement complex algorithms. As an example we have chosen the problem of enumerat…
