agglomerative clustering method

What is the agglomeration method?
Agglomerative Hierarchical Clustering (AHC) is a clustering (or classification) method which has the following advantages: It works from the dissimilarities between the objects to be grouped together.
A type of dissimilarity can be suited to the subject studied and the nature of the data.
What is agglomerative hierarchical clustering linkage methods?
Let's summarize the steps involved in Agglomerative Clustering:
Create n cluster for n data point ,one cluster for each data point.Compute proximity matrix i.e create a n×n matrix containing distance between each data point to each other.Merge the two closest cluster.Update the Matrix.
What are the steps for agglomerative clustering?
Steps for Agglomerative clustering can be summarized as follows:
1Step 1: Compute the proximity matrix using a particular distance metric.
2) Step 2: Each data point is assigned to a cluster.
3) Step 3: Merge the clusters based on a metric for the similarity between clusters.
4) Step 4: Update the distance matrix.
A Hierarchical clustering method works via grouping data into a tree of clusters.
Hierarchical clustering begins by treating every data point as a separate cluster.
Then, it repeatedly executes the subsequent steps: Identify the 2 clusters which can be closest together, and.

Agglomerative Clustering is a bottom-up approach, initially, each data point is a cluster of its own, further pairs of clusters are merged as one moves up the hierarchy.
