20100185423 | METHOD FOR DESCRIBING RELATIONS IN SYSTEMS ON THE BASIS OF AN ALGEBRAIC MODEL - A method for describing one or more relations in a physical or other system on me oasis of an algebraic model of the system comprises the steps of: a) collecting data comprising measurements of different quantities relating to the system; b) interpreting the measurements of the different quantities as evaluations of different variables, which together comprise a polynomial ring; c) calculating an ideal of the ring, the generators of which substantially vanish on the collected data; d) interpreting the generators as polynomial relations between the variables of the system; e) reformulating at least one of the polynomial relations as an algebraic model for one of the variables in terms of the other variables involved in this relation; and f) the algebraic model is induced to generate one or more governing relations between parameters that govern the system using only measured data of the system. The algebraic model used in the method according to the invention is also identified as the Approximate Buchberger-Moeller algorithm, which computes a substantially or approximately vanishing ideal of a finite set of points and which remains numerically stable if the points are imprecise measured data. | 07-22-2010 |
