WebOct 10, 2016 · As mentioned GMM-EM clustering gives you a likelihood estimate of being in each cluster and is clearly an option. However, if you want to remain in the spherical construct of k-means you could probably use a simpler assumption/formulation if you wanted to assign some "goodness score" to each point's clustering. dial it investmentsWebA K-means klaszterezés a felügyelt gépi tanulási algoritmus, amely az adattudományok területén az adattechnikák és -műveletek mélyebb készletének része.
