PPT-Hierarchical Clustering

Hierarchical Clustering Produces a set of nested clusters organized as a hierarchical tree Can be visualized as a dendrogram A treelike diagram that records the sequences of merges or splits. Hierarchical Clustering . Produces a set of . nested clusters . organized as a hierarchical tree. Can be visualized as a . dendrogram.

Cluster:. a collection of data objects that are “similar” to one another and thus can be treated collectively as one group. Pasring. Reporters: R98922004 . Yun-Nung. Chen,. R98922033 Yu-Cheng Liu.

Now, lets consider scenarios where it could be non-linear. We will discuss:. QDA. RDA. MDA. As before all these methods aim to MINIMIZE the probability of misclassification.. Lecture outline.

What is clustering?. Grouping set of documents into subsets or clusters.. The Goal of clustering algorithm is:. To create clusters that are coherent internally, but clearly different from each other.
