Are the events for any particular user ordered from 'most interested' to 'least interested' as well? Or is it the case that the only information that we can get form the 'train.csv' is that whether\r\n a particular user was interested or not interested of an event?</p>\r\n<p>Bonus question :). When you evaluate our answers, don't you have to have the correct ordering (again, from 'most interested' to 'least interested') for every user in the 'train.csv'? Just curious, how did you get that info? Did you ask users to rank/order\r\n events?</p>\r\n<p>Thanks</p>\r\n<p>Cheers,</p>\r\n<p>Ayman</p>",
