  • How do you find the accuracy of k-means clustering?

    Accuracy for clustering
    For clustering, we have to find the best match between the class labels and the cluster labels, so accuracy is defined by: accuracy(y,ˆy)=maxperm?P1nn?1?i=01(perm(ˆyi)=yi)

  • What is accuracy in clustering?

    The k-means cluster analysis command is efficient primarily because it does not compute the distances between all pairs of cases, as do many clustering algorithms, including the algorithm that is used by the hierarchical clustering command.

  • Is k-means clustering efficient?

    The curve looks like an elbow. In the above plot, the elbow is at k=3 (i.e., the Sum of squared distances falls suddenly), indicating the optimal k for this dataset is 3.
