摘要:
针对Cole-Cole参数的提取，本文提出自适应免疫-最小一乘算法。首先，通过制定自适应策略，并增设记忆单元，设计本算法对Cole-Cole参数的提取流程；其次，在标准生物阻抗数据集基础上分别添加3种不同噪声，并设置评价指标，对比分析自适应免疫-最小一乘算法与另外3种算法对Cole-Cole圆弧的拟合精度及Cole-Cole参数的提取结果；最后，基于自适应免疫-最小一乘算法，对其在噪声数据集下提取Cole-Cole参数的耗时长短及初值依赖性做出考量。实验结果表明，该算法相较于另外3种算法能够精准、快速地提取Cole-Cole参数，且对初值的依赖性不高。 【关键词】生物阻抗；自适应免疫算法；最小一乘法；Cole-Cole参数
Abstract:
Abstract: An adaptive immune-least absolute deviation algorithm is proposed for extracting Cole-Cole parameters. The extraction of Cole-Cole parameters by the proposed algorithm is realized by formulating adaptive policies and adding memory units. Then, 3 different kinds of noises are added to the standard data sets of the bioimpedance, and related evaluation indicators were set. Based on the fitting accuracy of Cole-Cole arcs and the extraction results of Cole-Cole parameters, the proposed adaptive immune-least absolute deviation algorithm is compared with other 3 algorithms. Finally, the time-consuming and dependence on the initial values of the proposed algorithm for extracting Cole-Cole parameters from the noise data sets are analyzed. Experimental results show that the Cole-Cole parameters can be extracted accurately and quickly by the proposed algorithm compared with other 3 algorithms, and that the dependence on the initial values is relatively low.
