Center node: "proximal algorithms and temporal differences for large linear systems extrapolation approximation and simulation"
  Abstract: In this paper we consider large linear fixed point problems and solution with proximal algorithms. We show that, under certain assumptions, there is a close connection between proximal iterations, which are prominent in numerical analysis and optimization, and multistep methods of the temporal difference type such as TD(lambda), LSTD(lambda), and LSPE(lambda), which are central in simulation-based approximate dynamic programming. As an application of this connection, we show that we may accelerate the standard proximal algorithm by extrapolation towards the multistep iteration, which generically has a faster convergence rate. We also use the connection with multistep methods to integrate into the proximal algorithmic context several new ideas that have emerged in the approximate dynamic programming context. In particular, we consider algorithms that project each proximal iterate onto the subspace spanned by a small number of basis functions, using low-dimensional calculations and simulation, and we discuss various algorithmic options from approximate dynamic programming.
