Our study reveals that (a) postpaid customers are more active in terms of service usage and (b) there are strong structural correlations in the mobile phone call network as connections between customers of the same subscription type are much more frequent than those between customers of different subscription types. Based on these observations we provide methods to detect the subscription type of customers by using information about their personal call statistics, an","authors_text":"Carlos Sarraute, Eric Fleury, Martin Minnoni, M\\'arton Karsai, Wei Du, Yongjun Liao","cross_cats":["cs.LG","physics.soc-ph","stat.ML"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.SI","submitted_at":"2017-06-30T12:27:11Z","title":"Prepaid or Postpaid?
