hi, Are there way to know if the algorithm of clustering give meaning or meaningless clusters?
thanks in advance
No products are associated with this question.
If you are doing k-means or other clustering that starts from random initial conditions, then you repeat the clustering a number of times with different conditions; the clusters that appear in more of the results are more probable.
If you are trying to determine the optimal number of clusters, then you have a Problem unless you can write down exactly what it means for a clustering to be optimal in your situation; there is no generally applicable definition of "optimal" that can be used.
