WebSep 22, 2024 · K-means clustering is an unsupervised learning algorithm, which groups an unlabeled dataset into different clusters. The "K" refers to the number of pre-defined clusters the dataset is grouped into. We'll implement the algorithm using Python and NumPy to understand the concepts more clearly. Given: K = number of clusters WebJul 13, 2024 · K-mean++: To overcome the above-mentioned drawback we use K-means++. This algorithm ensures a smarter initialization of the centroids and improves the quality of the clustering. Apart from initialization, the rest of the algorithm is the same as the standard K-means algorithm.
