+5 marksOne or more correct options

Consider the following code snippet:

Which of the following statements are true?

Consider the following code snippet:

Select all that apply.

  1. A

    If the model reaches convergence in under 20 iterations, it is guaranteed that every data point is mapped to its nearest centroid.

  2. B

    The value for number of clusters is a hyperparameter that can be validated using a silhouette score or the elbow method.

  3. C

    The algorithm will execute a total of 20 independent runs using different starting centroid seed

  4. D

    The initialization process will select 9 data points entirely at random to serve as the starting centroids.
