Hierarchical Clustering: Time and Space requirements

Hierarchical Clustering: Time and Space requirements. O(N 2 ) space since it uses the proximity matrix. N is the number of points. O(N 3 ) time in many cases There are N steps and at each step the size, N 2 , proximity matrix must be updated and searched
