The median is computed in each dimension (for each variable) with a Manhattan distance formula (think of walking or city-block distance, where you have to follow sidewalk paths). WebJul 24, 2024 · K-means Clustering Method: If k is given, the K-means algorithm can be executed in the following steps: Partition of objects into k non-empty subsets. Identifying the cluster centroids (mean point) of the current partition. Assigning each point to a specific cluster.
