Realization of nonlinear behaviors from organizing centers
Alessio Franci, Rodolphe Sepulchre
Borrowing the concept of organizing center from singularity theory, the paper proposes a methodology to realize nonlinear behaviors such as switches, relaxation oscillators, or bur…
Riemannian preconditioning
Bamdev Mishra, Rodolphe Sepulchre
This paper exploits a basic connection between sequential quadratic programming and Riemannian gradient optimization to address the general question of selecting a metric in Rieman…
AR Identification of Latent-variable Graphical Models
Mattia Zorzi, Rodolphe Sepulchre
The paper proposes an identification procedure for autoregressive gaussian stationary stochastic processes wherein the manifest (or observed) variables are mostly related through a…
Factor Analysis of Moving Average Processes
Mattia Zorzi, Rodolphe Sepulchre
The paper considers an extension of factor analysis to moving average processes. The problem is formulated as a rank minimization of a suitable spectral density. It is shown that i…
Reconstructing trajectories from the moments of occupation measures
Mathieu Claeys
Moment optimization techniques have been recently proposed to solve globally various classes of optimal control problems. As those methods return truncated moment sequences of occu…
