Clustering_method参数来设定不同聚类方法
WebK-Means is the ‘go-to’ clustering algorithm for many simply because it is fast, easy to understand, and available everywhere (there’s an implementation in almost any statistical or machine learning tool you care to use). K-Means has a few problems however. The first is that it isn’t a clustering algorithm, it is a partitioning algorithm. WebAug 23, 2024 · Household income. Household size. Head of household Occupation. Distance from nearest urban area. They can then feed these variables into a clustering algorithm to perhaps identify the following clusters: Cluster 1: Small family, high spenders. Cluster 2: Larger family, high spenders. Cluster 3: Small family, low spenders.
