| Abstract: | The self-organizing state space model provides an efficient approach to estimating unknown parameters in a nonlinear non-Gaussian state space model. However, a difficult problem is how to determinate the initial distributions of parameters for a self-organizing state space model. To address this problem, this paper proposes an algorithm to seek the initial distribution of parameters for a self-organizing state space model. The proposed algorithm is based on an efficient evolutionary computation model which has global search capability. It makes the initial distribution of parameters close to the true parameter situation. The results of numerical experiments show the effectiveness of the proposed algorithm. |
