Assign each point to the nearest cluster.

Webb11 apr. 2024 · The algorithm calculates the pairwise distances between all sequences and uses these distances to determine the closest neighbors. Once the closest neighbors are identified, the algorithm consolidates them into a new node, effectively reforming the star tree. This process is repeated until all sequences are connected in a fully resolved tree. 2.
