Implementing K-Means Clustering with K-Means
WebMar 30, 2024 · Indeed, k-means is a stochastic clustering technique, as the solution may depend on the initial conditions (cluster centers). There are several algorithms for choosing the initial cluster centers, but the most widely used is the K++ initialization, first described in 2007 by David Arthur and Sergei Vassilvitskii (5).
