Nettet3. nov. 2016 · Hierarchical clustering can’t handle big data well, but K Means can. This is because the time complexity of K Means is linear, i.e., O(n), while that of hierarchical is quadratic, i.e., O(n2). Since we start … As listed above, clustering algorithms can be categorized based on their cluster model. The following overview will only list the most prominent examples of clustering algorithms, as there are possibly over 100 published clustering algorithms.
