为提升长短期记忆网络(long short-term memory, LSTM)在船舶运动姿态领域的预测精度,同时简化参数调优的过程。针对船舶运动数据设计了双层模态分解策略,结合开普勒优化算法(Kepler optimization algorithm, KOA),提出一种船舶运动姿态多模态预测模型。采用改进的完全自适应噪声集合经验模态分解(improved complete ensemble empirical mode decomposition with adaptive noise, ICEEMDAN)和变分模态分解(variational mode decomposition, VMD)的双层模态分解(double-layer mode decomposition, DLMD)模式,对原始船舶运动姿态时序数据进行双层分解,解决了第一层分解存在的高频分量过度平滑问题,同时消除了高频噪声与有效信号在相同频带下的耦合干扰,提升了模型的预测效果;进一步在模型训练中引入KOA优化LSTM的超参数,解决了LSTM调参效率低、易陷入局部最优的问题。基于实船运动数据集开展消融实验和算法整体验证实验,消融实验验证了DLMD和KOA模块的独立贡献;算法整体验证实验结果验证了两个模块的共同作用,并表明了该模型能够对船舶横摇和纵摇姿态实现较高精度的预测及超参数组合的自动优化。
- Abstract:
-
To improve the prediction accuracy of the long short-term memory (LSTM) model in the field of ship motion attitude and simplify the parameter tuning process, a double-layer mode decomposition strategy is designed for ship motion data. Combined with the Kepler optimization algorithm (KOA), a multi-modal prediction model for ship motion attitude is proposed. This model adopts a double-layer mode decomposition (DLMD) scheme integrating improved complete ensemble empirical mode decomposition with adaptive noise (ICEEMDAN) and variational mode decomposition (VMD) to perform double-layer decomposition on the original time-series data of ship motion attitude. This decomposition resolves the over-smoothing issue of high-frequency components in the first-layer decomposition, while eliminating the coupling interference between high-frequency noise and effective signals in the same frequency band, thus improving the prediction performance of the model. Furthermore, KOA is introduced to optimize the hyperparameters of LSTM during model training, which addresses the problems of low efficiency and easy trapping in local optima in LSTM parameter tuning. Ablation experiments and overall algorithm verification experiments are conducted based on a real ship motion dataset. The ablation experiments verify the independent contributions of the DLMD and KOA modules; the results of the algorithm verification experiments confirm the synergistic effect of the two modules, and demonstrate that the proposed model can achieve high-precision prediction of ship roll and pitch attitudes as well as automatic optimization of hyperparameter combinations.
