We propose a new computationally efficient modeling method that captures existing translation symmetry in a system. To obtain a low order approximate system of ODEs prior to performing Karhunen Loeve expansion we process the available data set using a "centering" procedure. This approach has been shown to be efficient in nonlinear scalar wave equations.doi:10.1109/cdc.1998.758639 fatcat:pkzysp226fhhdlmqu7ppymuode
