The test was carried out by dividing the ICT interference data and calculating the cluster One way to ensure that government programs and assistance for each province are right on target is to create a model of grouping or clustering provinces in Indonesia based on poverty levels. For some types of unsupervised learning analyses, machine learning practitioners have typically needed to examine a plot and make a somewhat subjective judgement call to tune the model (the so-called "elbow method"). The number of samples contained in each category decreasesand the samples are , The Elbow method is pretty far from the others, at only 13% (4 out of 30). In this paper, a mixed method comprising of nano topology, a modified k-means clustering and an interval superimposition technique is used for finding fuzzy periodic clusters in the subspace The elbow method provides a simple and intuitive visualization to choose the best k, and it often works well in practice to find a reasonable number of clusters if the data has a clear grouping. : The Clustering, a traditional machine learning method, plays a significant role in data analysis. 2. 3% accuracy, however it only works for separate humerus X-rays and do not work if the other bones are involved in elbow X-ray image.
