Questions & Step-by-Step Solutions

Which of the following algorithms is commonly used for clustering numerical data?
  • Step 1: Understand what clustering means. Clustering is a way to group similar data points together.
  • Step 2: Know that numerical data consists of numbers that can be measured or counted.
  • Step 3: Learn about K-Means, which is a method used to cluster numerical data.
  • Step 4: K-Means works by choosing a number 'K' which represents how many clusters you want to create.
  • Step 5: The algorithm then randomly selects 'K' points as the initial cluster centers.
  • Step 6: It assigns each data point to the nearest cluster center based on distance.
  • Step 7: After assigning all points, it recalculates the cluster centers by finding the average of the points in each cluster.
  • Step 8: Steps 6 and 7 are repeated until the cluster centers no longer change significantly.
