Vessel trajectory prediction based on improved multi-output support vector
In order to ensure the rapid,safe and reliable collision avoidance of intelligent vessel,this paper proposes a vessel track prediction model based on the improved salp swarm algorithm(SSA)multi output support vector is proposed.The multi output support vector model used in this paper can model the vessel as a whole,and the vessel model built can predict the changes of vessel track status at the same time.For the super parameters in the model,the improved SSA is used for optimization.The algorithm adds the characteristics of adaptive weight and outlier algorithm,avoiding the problem of premature algorithm and local optimization that is easy to get stuck in high-dimensional.Finally,the proposed method is validated by measured data and compared with other common models.The results show that the proposed method is feasible and effective.
