Implementing K-Means Clustering using Python Let’s code! The first step is importing the required libraries. 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.
