WebExercise 2: K-means clustering on bill length and depth. The kmeans() function in R performs k-means clustering. Use the code below to run k-means for \(k = 3\) clusters. Why is it important to use set.seed()? (In practice, it’s best to run the algorithm for many values of the seed and compare results.)

WebK-means clustering is one of the most basic types of unsupervised learning algorithm. This algorithm finds natural groupings in accordance with a predefined similarity or distance measure. The distance measure can be any of the following: To understand what a distance measure does, take the example of a bunch of pens. 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 (cluster …
