| 英文摘要 |
| In the immunized neural network identification (INNI),the changeable neuro-system model (CNS),which is used to compensate the disturbance of system,is established by choosing building blocks chosen with the genetic algorithm (GA).When the number and category of the building blocks are great,the search space dimension of CNS is very high,and its search time is long.One of effective approaches to shorten search time is to reduce the dimension of search space.In immune system,the antibodies against certain antigens is searched under the ground of antibody recognization ball (RB).Because RB offers approximate antibodies at the beginning of antibody searching process,many useful genes neednot search.In this way the search space dimension of antibody is reduced drastically,and the search speed of antibody is very fast.With regard to this mechanism,an approach of reducing search space dimension is proposed based on artificial immune system(AIS):A kind of new AIS—antibody recognization ball network (ARBN) is constructed,and its training algorithm is presented.The ARBN is used to generalize,memorize the characteristics of building block combinations and create the effective initial group of GA.Simulation results show that with this approach the searching speed of CNS can be quickened effectively. |
