Ward’s Method: This approach of … In statistics, Ward's method is a criterion applied in hierarchical cluster analysis. Ward's minimum variance method is a special case of the objective function approach originally presented by Joe H. Ward, Jr. Ward suggested a general agglomerative hierarchical clustering procedure, where the criterion for choosing … Ver mais Ward's minimum variance criterion minimizes the total within-cluster variance. To implement this method, at each step find the pair of clusters that leads to minimum increase in total within-cluster variance after … Ver mais • Everitt, B. S., Landau, S. and Leese, M.

Ver mais Ward's minimum variance method can be defined and implemented recursively by a Lance–Williams algorithm. The Lance–Williams algorithms are an infinite family of … Ver mais The popularity of the Ward's method has led to variations of it. For instance, Wardp introduces the use of cluster specific feature weights, following the intuitive idea that features could have different degrees of relevance at different clusters. Ver mais
