WebAs a fundamental unsupervised learning task, hierarchical clustering has been extensively studied in the past decade. In particular, standard metric formulations as hierarchical k-center, k-means, and k-median received a lot of attention and the problems have been studied extensively in different models of computation. WebHá 15 horas · In all the codes and images i am just showing the hierarchical clustering with the average linkage, but in general this phenomenon happens with all the other linkages (single and complete). The dataset i'm using is the retail dataset, made of 500k istances x 8 variables. It's on UCI machine learning dataset.
