Abstract
A system and method for generating a subscriber churn prediction includes receiving call detail records from a network operator detailing communication between subscribers of the network operator and determining tie-strengths between subscribers based on the call detail records. The system and method further includes generating a net churn influence accumulated at each subscriber from the tie-strengths by propagating churner influence between subscribers due to churn events.
Claims15
A system for generating a subscriber churn prediction comprising:
- a data input device adapted to receive call detail records from a network operator detailing communication for at least one subscriber of the network operator;
- and
- at least one processor connected to the data input device, the at least one processor adapted to execute a churn prediction program that determines tie-strengths between connected subscribers of the network operator based on a weighted sum of a plurality of normalized call attributes from the call detail records and derives at least one social metric with the tie-strengths;
- wherein the churn prediction program generates the subscriber churn prediction based at least on the at least one social metric.
A computerized method for generating a prediction of subscriber churn comprising the steps of:
- receiving, by a churn prediction program executing on a computer processor, call detail records from a network operator detailing communication for at least one subscriber of the network operator;
- determining, by the churn prediction program executing on the computer processor, tie-strengths between connected subscribers on the network operator based on a weighted sum of a plurality of normalized call attributes from the call detail records;
- deriving, by the churn prediction program executing on the computer processor, at least one social metric with the tie-strengths;
- and
- generating, by the churn prediction program executing on the computer processor, a subscriber churn prediction based at least on the at least one social metric.
A non-transitory, tangible computer-readable medium storing instructions adapted to be executed by a computer processor to perform a method for generating a subscriber churn prediction, said method comprising the steps of:
- receiving, by a churn prediction program executing on the computer processor, call detail records from a network operator detailing communication for at least one subscriber of the network operator;
- determining, by the churn prediction program executing on the computer processor, tie-strengths between connected subscribers on the network operator based on a weighted sum of a plurality of normalized call attributes from the call detail records;
- deriving, by the churn prediction program executing on the computer processor, at least one social metric with the tie-strengths;
- and
- generating, by the churn prediction program executing on the computer processor, a subscriber churn prediction based at least on the at least one social metric.
