if loglikelihood has increased the number of clusters is increased by 1 and the program continues at step 2. the loglikelihood is averaged over all 10 results.ĥ. EM is performed 10 times using the 10 folds the usual CV way.Ĥ. the training set is split randomly into 10 folds.ģ. The cross validation performed to determine the number of clusters is done in the following steps:Ģ. EM can decide how many clusters to create by cross validation, or you may specify apriori how many clusters to generate. Simple EM (expectation maximisation) class.ĮM assigns a probability distribution to each instance which indicates the probability of it belonging to each of the clusters.
