基于改进鱼鹰优化模糊C均值聚类的交通运行状态判别

Traffic Operation State Discrimination Based on Fuzzy C-means Clustering Optimized by Improved Osprey Optimization Algorithm

  • 摘要: 在对交通参数数据进行聚类分析的过程中,传统模糊C均值(FCM)存在聚类中心初始化过程随机性较大,以及由随机初始化而导致聚类中心波动、陷入局部最优解等问题。针对这些缺陷,提出了一种基于改进鱼鹰优化算法(IOOA)的FCM聚类方法,并应用于对交通运行状态的准确划分判别中。所提IOOA-FCM采用Logistic-Chebyshev混合混沌映射来增强种群多样性,并设计动态混合寄生共生策略平衡勘探与开发能力,同时结合记忆增强反向学习机制来提升全局寻优性能。利用标准测试函数对IOOA-FCM和同类其他先进OOA、SSA、GWO、MFO算法进行比较。结果表明,相较于其他算法,所提的IOOA-FCM在收敛速度和精度等方面表现较好。在PeMSD8公开交通数据集上进行算法验证,实验结果表明,相对于比较算法,提出的IOOA-FCM算法能够更快速、准确地划分交通运行状态。

     

    Abstract: In the process of clustering analysis of traffic parameter data, the traditional fuzzy C-means (FCM) algorithm suffers from problems such as high randomness in the initialization process of clustering centers, which can cause fluctuations in clustering centers and fall into local optimal solutions. We propose an FCM optimization method based on Improved Osprey Optimization Algorithm (IOOA) to address these shortcomings, and apply it to achieving accurate classification and discrimination of traffic operation state. the proposed IOOA-FCM uses Logistic-Chebyshev hybrid chaotic mapping to enhance population diversity, and designs a dynamic mixed parasitic symbiosis strategy to balance exploration and development capabilities, combined with a memory-enhanced reverse learning mechanism to improve global optimization performance. We use standard test functions to compare IOOA-FCM with other advanced algorithms, including OOA, SSA, GWO, and MFO. The results show that the proposed IOOA-FCM performs better in terms of convergence speed and accuracy than other algorithms. We then validate IOOA-FCM on the PeMSD8 public traffic dataset, and the experimental results show that compared to the comparative algorithms, the proposed IOOA-FCM algorithm can more quickly and accurately classify the traffic operation state.
