| 为了克服传统群智能算法在求解盲源分离(BSS)问题时收敛速度慢和分离精度差的缺点,提出一种基于改进型象群优
化(IEHO)算法的 BSS 方法。 该方法利用独立性原则,融合分离信号的峭度和互信息来构建目标函数。 在氏族更新阶段,通过
改进算法比例因子并加入邻域搜索,提高了算法搜索方式的多样性;在分离阶段,引入量子粒子群优化策略,提高了算法的全局
搜索能力。 仿真结果表明,与传统的象群优化算法和粒子群优化算法相比,IEHO 算法的寻优效果较好,并成功实现了图像信号
和语音信号的盲源分离,分离精度更高,收敛速度更快。 |

| In order to overcome the disadvantages of slow convergence speed and poor separation accuracy when solving blind source
separation (BSS) problems in traditional swarm intelligence algorithms, a BSS method based on improved elephant herding optimization
(IEHO) is proposed. The method uses the principle of independence to construct the objective function, combining the kurtosis and the
mutual information of separating signals. In the clan update stage, the scale factor of algorithm is modified as well as exploiting the
neighborhood search to improve the diversity of the search. In the separation stage, the quantum-behaved particle swarm optimization
strategy is introduced to improve the global search ability of the algorithm. The simulation results show that the IEHO algorithm has a
better optimization effect compared with the traditional elephant herding optimization algorithm and the particle swarm optimization
algorithm. Meanwhile, the proposed algorithm can also realize blind source separation of images and speech successfully, with higher
separation accuracy and faster convergence speed. |
