WebWe first built clusters using the K-Means Clustering algorithm, and the optimal number of clusters came out to be 4. This was obtained through the elbow method and Silhouette score analysis. Then clusters were built using the Agglomerative clustering algorithm, and the optimal number of clusters came out to be 8. WebAug 19, 2024 · The k-means algorithm uses an iterative approach to find the optimal cluster assignments by minimizing the sum of squared distances between data points and their assigned cluster centroid. So far, we have understood what clustering is and the different properties of clusters. But why do we even need clustering?
