Webk-means clustering is a method of vector quantization, originally from signal processing, that aims to partition n observations into k clusters in which each observation belongs to the cluster with the nearest mean ... WebAug 14, 2024 · Easy to implement: K-means clustering is an iterable algorithm and a relatively simple algorithm. In fact, we can also perform k-means clustering manually as we did in the numerical example. Scalability: We can use k-means clustering for even 10 records or even 10 million records in a dataset. It will give us results in both cases.
