Which of the Following Statements About the K-Means Clustering Algorithm

question 32

Multiple Choice

Which of the following statements about the k-means clustering algorithm is false?

• A) Each cluster of samples is grouped around a centroid-the cluster's center point.
• B) Initially, the algorithm chooses k centroids at random from the dataset's samples. Then the remaining samples are placed in the cluster whose centroid is the closest.
• C) The centroids are iteratively recalculated and the samples re-assigned to clusters until, for all clusters, the distances from a given centroid to the samples in its cluster are maximized.
• D) The algorithm's results are a one-dimensional array of labels indicating the cluster to which each sample belongs, and a two-dimensional array of centroids representing the center of each cluster.
