Webbk-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 (cluster centers or cluster centroid), serving as a prototype of the cluster.This results in a partitioning of the data space into Voronoi cells. Webb1 aug. 2024 · v = 2 1 60 + 1 40. which happens to be what we call the harmonic mean. If the certain distance is something else, say k km, then you get. v = 2 k k 60 + k 40. which is the same number. If he instead had travelled a certain time t h at 60, then the same time at 40, you would get. v = 60 t + 40 t 2 t = 60 + 40 2.

Webb9 okt. 2024 · It’s often simply called the mean or the average. But there are some other types of means you can calculate depending on your research purposes: Weighted mean: some values contribute more to the mean than others.
