SUMMARY:Séminaire de Jared Miller (ETH Zurich)
DESCRIPTION:\n 	Lien visio : Teams\n 	Titre : Structure\, Analysis\, and 
 Synthesis of First-Order Algorithms\n 	Résumé : Optimization algorithms
  can be interpreted through the lens of dynamical systems as the interconn
 ection of a linear system and a set of subgradient nonlinearities. This dy
 namical systems formulation allows for the analysis and synthesis of optim
 ization algorithms by solving robust control problems. In this work\, we u
 se the celebrated internal model principle in control theory to structural
 ly factorize convergent optimization algorithms into a suitable network-de
 pendent internal model and a core subcontroller. As the key benefit\, we r
 eveal that this permits us to synthesize optimization algorithms even if i
 nformation is transmitted over networks featuring phenomena such as time d
 elays or channel memory. Design of these certified-exponentially-convergen
 t networked algorithms is achieved under bisection in the convergence rate
  through either a nonconvex local search or by alternation of convex semid
 efinite programs. We demonstrate factorization of existing optimization al
 gorithms and the automated synthesis of new optimization algorithms in the
  networked setting.\n
