Your K-Means clustering algorithm is converging to a local minimum. What role might centroid initialization play in this, and how could you address it?

  • Increase the number of clusters
  • Initialize centroids based on labels
  • Poor initialization; Try multiple random initializations
  • Use a fixed number of centroids
Converging to a local minimum in K-Means is often due to poor initialization. Running the algorithm multiple times with different random initializations can help avoid local minima and lead to a more globally optimal solution.
