Instead of reducing the Euclidean distance between cluster objects and cluster means (centroids) to reduce a cost function, K-modes replaces cluster means with modes and uses a “matching dissimilarity” measure to update cluster modes.

WebBy using k-means clustering, I clustered this data by using k=3. Now, I want to calculate the distance between each data point in a cluster to its respective cluster centroid. I have tried to calculate euclidean distance between each data point and centroid but somehow I am failed at it. My code is as follows:

WebThe following linkage methods are used to compute the distance d(s, t) between two clusters s and t. The algorithm begins with a forest of clusters that have yet to be used in the hierarchy being formed. When two clusters s and t from this forest are combined into a single cluster u, s and t are removed from the forest, and u is added to the ...
