Introduction to Clustering algorithms
Clustering (clustering) is a type of unsupervised learning (unsupervised learning) that divides a set of data into several categories, with the data in each class as similar as possible, while maximizing the differences between classes. By clustering, you can provide references for sample selection, root cause analysis, or as a preprocessing
