Web30 de jan. de 2024 · The very first step of the algorithm is to take every data point as a separate cluster. If there are N data points, the number of clusters will be N. The next step of this algorithm is to take the two closest data points or clusters and merge them to form a bigger cluster. The total number of clusters becomes N-1. WebK-means. K-means is an unsupervised learning method for clustering data points. The algorithm iteratively divides data points into K clusters by minimizing the variance in each cluster. Here, we will show you how to estimate the best value for K using the elbow method, then use K-means clustering to group the data points into clusters. WebX = dataset.iloc [:, [3,4]].values.
