# K-means and maximum likelihood!

Is there any relation between k-means and the maximum-likelihood estimate in unsupervised learning? Any references would be appreciates!

• What have you tried? Have you tried interpreting k-means as EM algorithm already? Nov 9, 2014 at 21:53
• That was the idea.... I read about EM can be view as k-means generalization... But I can't find any proof. Can anyone help me? Nov 10, 2014 at 17:07
• It's actually rather straightforward... first, have a look at e.g. Mclust in R, which is the R implementation of EM, and understand the model parameter; in particular the E model. Nov 10, 2014 at 18:31
• Could you be more specific? Thank you so much! Nov 10, 2014 at 21:20
