Classification: CPC G | IPC G

Claim 12:
13. An apparatus comprising:
a processor; and
a storage medium for tangibly storing thereon program logic for execution by the processor, the stored program logic causing the processor to perform the operations of:
receiving a record, the record including a plurality of fields;
selecting a value associated with a selected field in the plurality of fields;
querying a lookup table using the value, the lookup table comprising a mapping of values to aggregated statistics, wherein querying a lookup table includes determining that the lookup table is out of date by determining if a change in size of a unified dataset storing aggregated statistics exceeds a pre-configured size threshold and updating the lookup table in response;
receiving an aggregated statistic based on the querying;
generating a feature vector by annotating the record with the aggregated statistic; and
inputting the feature vector to a predictive model.
