WebOct 24, 2024 · K-means aims to minimize the total squared error from a central position in each cluster. These central positions are called centroids. On the other hand, k-medoids attempts to minimize the sum of dissimilarities between objects labeled to be in a cluster and one of the objects designated as the representative of that cluster. WebIn K-medoids Clustering, instead of taking the centroid of the objects in a cluster as a reference point as in k-means clustering, we take the medoid as a reference point. A medoid is a most centrally located object in the Cluster or whose average dissimilarity to all the objects is minimum. Hence, the K-medoids algorithm is more robust to ...
