WebJan 16, 2015 · This doesn't ensure that k-means works. Scaling depends on the meaning of your data set. And if you have more than one cluster, you would want every cluster (independently) to have the same variance in every variable, too. Here is a classic counterexample of data sets that k-means cannot cluster. Both axes are i.i.d. in each … WebPrincipal Data Engineer. YUHIRO. Nov 2024 - Nov 20241 year 1 month. India.
