julia - How to identify standalone spheres in Julia?

Question

How is it possible to get rid of standalone spheres? Or how can I manipulate the data set, that I don't plot spheres, which are not connected together? (Means the surface of a sphere does't touch another sphere) In the example there are some spheres which aren't connected to the main pile. The data set includes x-,y-,z-coordinates and the volume of each sphere.

Thank you, Tom

您要求的东西称为异常检测，它不是绘制图形的问题，而是用于分析多维数据的一系列算法。

有很多方法可以解决这个问题，但也许你可以先看看：https ://github.com/milanflach/MultivariateAnomalies.jl

另一种方法是使用聚类方法（参见https://github.com/JuliaStats/Clustering.jl），例如 DBSCAN，然后解释小集群和异常，讨论参见https://towardsdatascience.com/best -聚类算法用于异常检测-d5b7412537c8。
