Question 506
|
A clustering technique that permits a convenient graphical display is :
|
partition based clustering
|
|
|
probabilistic model based clustering
|
|
|
hierarchical clustering
|
|
|
agglomerative clustering
|
Question 506 Explanation:
→ Hierarchical methods of cluster analysis permit a convenient graphical display in which the entire sequence of merging(or splitting) because of its tree like nature, the display has the name of dendrogram.
Types:
1. Agglomerative: This is a “bottom-up” approach: each observation starts in its own cluster, and pairs of clusters are merged as one moves up the hierarchy.
2. Divisive: This is a “top-down” approach: all observations start in one cluster, and splits are performed recursively as one moves down the hierarchy.
Types:
1. Agglomerative: This is a “bottom-up” approach: each observation starts in its own cluster, and pairs of clusters are merged as one moves up the hierarchy.
2. Divisive: This is a “top-down” approach: all observations start in one cluster, and splits are performed recursively as one moves down the hierarchy.
