Abstract
TES (Transform-Expand-Sample) is a versatile class of stationary stochastic processes which can model arbitrary marginals, a wide variety of autocorrelation functions, and a broad range of sample path behaviors. An algorithmic method replaces the previously relied upon heuristic search, thereby automating TES modeling for simulation analysis. The algorithm is solved in a nonlinear programming setting, which takes advantage of fast and accurate computation of TES autocorrelation functions and their partial derivatives to implement a steepest-descent technique, preferably based on Zoutendijk's Feasible Direction Method. The method has particular application to data compression and specifically compressed video.
