Questions & Step-by-Step Solutions

In hierarchical clustering, what is the result of the agglomerative approach?
Correct Answer: Larger clusters formed by merging individual data points.
  • Step 1: Start with each data point as its own individual cluster.
  • Step 2: Calculate the similarity or distance between each pair of clusters.
  • Step 3: Identify the two clusters that are the most similar (or closest together).
  • Step 4: Merge these two clusters into a single larger cluster.
  • Step 5: Repeat steps 2 to 4 until all data points are merged into one single cluster.
