Answer 1

Answer:

In addition, provide reasoning one example is BIRCH,a multi-phase clustering method that integrates hierarchical clustering( as a pre-processing steps) with other clustering techniques

Answer 2

Answer:

As per the data given in the above question.

BIRCH is an example of specific clustering methods can be integrated.

• One example is BIRCH, a multi-phase clustering method that integrates hierarchical clustering (as a pre-processing step) with other clustering techniques.It begins by partitioning objects hierarchically using treestructures, and then applies other clustering algorithms (such as iterative partitioning) to refine the clusters.
• BIRCH incrementally constructs a clustering feature tree (CF tree), which isaheight-balancedtreethatstores the clustering features (summarized statistics) for a hierarchical clustering.
• BIRCH consists of two phases .
• Phase 1 (microclustering) scans the database to build an initial in-memory CF tree, which can beviewed as a multilevel compression of the data that tries to preserve the inherent clustering structure of the data.
• Phase 2 (macroclustering) applies another type of clustering algorithm (such as iterative relocation)tocluster the leaf nodes of the CF-tree, which removes sparse clusters as outliers and groups dense clusters intolarger ones.Integrating different types of clustering methods may help overcome some of the weaknesses of the individualapproaches. For example, by integrating hierarchical clustering with other clustering techniques.
