Calculates center coordinates of each cluster
calc_centers(X, centers, labels)
| X | array Data points of dimension (n,d) |
|---|---|
| centers | array Coordinates of previous cluster centers, dimension (k,d) (used only to determine number of centers k) |
| labels | array Cluster assignments for each point in X, dimension (n,1) |
array Center coordinate for each cluster, dimension (k,d)
