- Abstract:
-
Nonparametric modeling methods are widely used in modeling ship maneuvering motions. This study introduces a v-support vector regression (v-SVR) nonparametric modeling method based on a mixed kernel function (MK), optimized through a genetic algorithm (GA) called GA-MK-v-SVR. The MK aims to improve the performance of v-SVR by combining radial basis functions with polynomial kernel functions, thus capturing both global and local characteristics. A GA is employed to fine-tune the hyper-parameters. The performance of GA-MK-v-SVR was evaluated by using KVLCC2 free-running test data provided by SIMMAN 2008, and the results were compared with several maneuvering models. Experimental results show that the proposed GA-MK-v-SVR model delivers impressive prediction accuracy and robust generalization capabilities for ship maneuvering motion modeling.
