what classifiers can I use if I am only given three columns one is the id of the person and other is the event and time of happening  and I have to predict the next 10 events that will happen with each id.should I just count the frequency of events and give the top 10? I am totally confused with the problem statement.should I use k nearest neighbor and go with the recency of events???in the dataset id  is patient_id and event is the treatment_he_had
confused with the classifier to pick
