This paper aims at estimating pathological subjects from a population through various physical information using genetic algorithm (GA). For comparison purposes, -Means (KM) clustering algorithm has also been used for the estimation. Dataset consisting of some physical factors (age, weight, and height) and tibial rotation values was provided from the literature. Tibial rotation types are four groups as RTER, RTIR, LTER, and LTIR. Each tibial rotation group is divided into three types. Narrow (Type 1) and wide (Type 3) angular values were called pathological and normal (Type 2) angular values were called nonpathological. Physical information was used to examine if the tibial rotations of the subjects were pathological. Since the GA starts randomly and walks all solution space, the GA is seen to produce far better results than the KM for clustering and optimizing the tibial rotation data assessments with large number of subjects even though the KM algorithm has similar effect with the GA in clustering with a small number of subjects. These findings are discovered to be very useful for all health workers such as physiotherapists and orthopedists, in which this consequence is expected to help clinicians in organizing proper treatment programs for patients.
本文旨在通过遗传算法(GA)利用各种身体信息从人群中估计病理受试者。为了进行比较,还使用了K均值(KM)聚类算法进行估计。文献提供了由一些身体因素(年龄、体重和身高)以及胫骨旋转值组成的数据集。胫骨旋转类型分为四组,即RTER、RTIR、LTER和LTIR。每个胫骨旋转组又分为三种类型。狭窄(类型1)和宽泛(类型3)的角度值被称为病理性的,而正常(类型2)的角度值被称为非病理性的。利用身体信息来检查受试者的胫骨旋转是否为病理性的。由于遗传算法是随机启动并遍历所有解空间,因此在对大量受试者的胫骨旋转数据评估进行聚类和优化时,遗传算法产生的结果远优于K均值算法,尽管在对少量受试者进行聚类时,K均值算法与遗传算法具有相似的效果。这些发现被证明对所有医护人员,如物理治疗师和骨科医生非常有用,预计这一结果将有助于临床医生为患者制定合适的治疗方案。
