Title: | Degeneracy of time series models : the best model is not always the correct model | Authors: | Judd, K Nakamura, T |
Issue Date: | Sep-2006 | Source: | Chaos, Sept. 2006, v. 16, no. 3, 033105, p. 1-3 | Abstract: | There are a number of good techniques for finding, in some sense, the best model of a deterministic system given a time series of observations. We examine a problem called model degeneracy, which has the consequence that even when a perfect model of a system exists, one does not find it using the best techniques currently available. The problem is illustrated using global polynomial models and the theory of Gröbner bases. | Keywords: | Times series Nonlinear dynamical systems Chaos Polynomials |
