WebNov 3, 2024 · K-Means++: This is the default method for initializing clusters. The K-means++ algorithm was proposed in 2007 by David Arthur and Sergei Vassilvitskii to avoid poor clustering by the standard K-means algorithm. K-means++ improves upon standard K-means by using a different method for choosing the initial cluster centers. WebDec 6, 2016 · K-means clustering is a type of unsupervised learning, which is used when you have unlabeled data (i.e., data without defined categories or groups). The goal of this algorithm is to find groups in the data, with the number of groups represented by the variable K. The algorithm works iteratively to assign each data point to one of K groups …
