Abstract

Crackles extracted from lung sounds recorded from pathological subjects were modelled using two different sets of parameters. The first set consisted of conventional parameters used widely by physicians. The second set consisted of Prony frequencies and damping coefficients obtained from the Prony model of order one. The crackles were clustered with no a priori information about the diseases using iterative partitional clustering. Clustering using either models shows that there is a relationship between crackles and lung diseases.
呼吸裂纹的聚类分析
从病理受试者记录的肺音中提取的噼啪声使用两组不同的参数进行建模。第一组由医生广泛使用的常规参数组成。第二组由一阶proony模型得到的proony频率和阻尼系数组成。采用迭代分段聚类方法,对无先验疾病信息的裂纹进行聚类。两种模型的聚类结果表明,裂纹与肺部疾病之间存在关联。
